Soldering  
1.1  
Leaded NTC thermistors  
Leaded thermistors comply with the solderability requirements specified by CECC.  
When soldering, care must be taken that the NTC thermistors are not damaged by excessive  
heat. The following maximum temperatures, maximum time spans and minimum distances have  
to be observed:  
Dip soldering  
max. 260 °C  
max. 4 s  
Iron soldering  
max. 360 °C  
max. 2 s  
Bath temperature  
Soldering time  
Distance from thermistor  
min. 6 mm  
min. 6 mm  
Under more severe soldering conditions the resistance may change.  
1.2 Leadless NTC thermistors  
In case of NTC thermistors without leads, soldering is restricted to devices which are provided  
with a solderable metallization. The temperature shock caused by the application of hot solder  
may produce fine cracks in the ceramic, resulting in changes in resistance.  
To prevent leaching of the metallization, solder with silver additives or with a low tin content  
should be used. In addition, soldering methods should be employed which permit short soldering  
times.  
1.3  
SMD NTC thermistors  
SMD NTC thermistors can be provided with a nickel barrier termination or on special request with  
silver-palladium termination. The usage of mild, non-activated fluxes for soldering is recommend-  
ed as well as a proper cleaning of the PCB.  
Nickel barrier termination  
The nickel barrier layer of the silver/nickel/tin termination (see figure 1) prevents leaching of the  
silver base metalization layer. This allows great flexibility in the selection of soldering parameters.  
The tin prevents the nickel layer from oxidizing and thus ensures better wetting by the solder. The  
nickel barrier termination is suitable for all commonly-used soldering methods.  
Note: SMD NTCs with AgPd termination are not approved for lead-free soldering.

Conductive adhesion  
An alternative to soldering is the gluing of thermistors with conductive adhesives. The benefit of  
this method is that it involves no thermal stress. The adhesives used must be chemically inert.  
3
Clamp contacting  
Pressure contacting by means of clamps is particularly suitable for applications involving frequent  
switching and high turn-on powers.  
4
Robustness of terminations (leaded types)  
The leads meet the requirements of IEC 60068-2-21. They may not be bent closer than 4 mm  
from the solder joint on the thermistor body or from the point at which they leave the feed-  
throughs. During bending, any mechanical stress at the outlet of the leads must be removed. The  
bending radius should be at least 0.75 mm.  
Tensile strength: Test Ua1:

0.25 <  
0.35 <  
0.50 <  
0.80 <  
Bending strength: Test Ub:  
Two 90°-bends in opposite directions at a weight of 0.25 kg.  
Torsional strength: Test Uc: severity 2  
The lead is bent by 90° at a distance of 6 to 6.5 mm from the thermistor body.  
The bending radius of the leads should be approx. 0.75 mm. Two torsions of  
180° each (severity 2).  
When subjecting leads to mechanical stress, the following should be observed:  
Tensile stress on leads  
During mounting and operation tensile forces on the leads are to be avoided.  
Bending of leads  
Bending of the leads directly on the thermistor body is not permissible.  
A lead may be bent at a minimum distance of twice the wire's diameter +2 mm from the solder  
joint on the thermistor body. During bending the wire must be mechanically relieved at its outlet.  
The bending radius should be at least 0.75 mm.

Sealing and potting  
When thermistors are sealed, potted or overmolded, there must be no mechanical stress caused  
by thermal expansion during the production process (curing / overmolding process) and during  
later operation. The upper category temperature of the thermistor must not be exceeded. Ensure  
that the materials used (sealing / potting compound and plastic material) are chemically neutral.  
6
Cleaning  
Washing processes may damage the product due to the possible static or cyclic mechanical  
loads (e.g. ultrasonic cleaning). They may cause cracks to develop on the product and its parts,  
which might lead to reduced reliability or lifetime.  
7
Storage  
In order to maintain their solderability, thermistors must be stored in a non-corrosive atmosphere.  
Humidity, temperature and container materials are critical factors.  
Do not store SMDs where they are exposed to heat or direct sunlight. Otherwise, the packing ma-  
terial may be deformed or SMDs may stick together, causing problems during mounting. After  
opening the factory seals, such as polyvinyl-sealed packages, use the SMDs as soon as possible.  
The components should be left in the original packing. Touching the metallization of unsoldered  
thermistors may change their soldering properties.  
Storage temperature:  
25 °C up to 45 °C  
Relative humidity (without condensation):  
75% annual mean  
<95%, maximum 30 days per annum  
Solder the thermistors listed in this data book after shipment from EPCOS within the time speci-  
fied:  
SMDs with nickel barrier termination: 12 months  
SMDs with AgPd termination:  
Leaded components:  
6 months  
24 months

Placement and orientation of SMD NTC thermistors on PCB  
a) Component placement  
It is recommended that the PC board  
should be held by means of some  
adequate supporting pins such as  
shown left to prevent the SMDs from  
being damaged or cracked.  
b) Cracks  
When placing a component near an  
area which is apt to bend or a grid  
groove on the PC board, it is advisable  
to have both electrodes subjected to  
uniform stress, or to position the  
component's electrodes at right angles  
to the grid groove or bending line (see  
c) Component orientation).  
c) Component orientation  
Choose a mounting position that  
minimizes the stress imposed on the  
chip during flexing or bending of the  
board.

Cautions and warnings  
See "Important notes".  
Storage  
Store thermistors only in original packaging. Do not open the package prior to processing.  
Storage conditions in original packaging: storage temperature 25 °C ... +45 °C, relative  
humidity 75% annual mean, <95% maximum 30 days per annum, dew precipitation is  
inadmissible.  
Do not store thermistors where they are exposed to heat or direct sunlight. Otherwise, the  
packing material may be deformed or components may stick together, causing problems during  
mounting.  
Avoid contamination of thermistor surface during storage, handling and processing.  
Avoid storage of thermistors in harmful environments like corrosive gases (SOx, Cl etc).  
Use the components as soon as possible after opening the factory seals, i.e. the  
polyvinyl-sealed packages.  
Solder thermistors within the time specified after shipment from EPCOS.  
For leaded components this is 24 months, for SMD components with nickel barrier termination  
12 months, for SMD components with AgPd termination 6 months.  
Handling  
NTC thermistors must not be dropped. Chip-offs or any other damage must not be caused  
during handling of NTCs.  
Do not touch components with bare hands. Gloves are recommended.  
Avoid contamination of thermistor surface during handling.  
Washing processes may damage the product due to the possible static or cyclic mechanical  
loads (e.g. ultrasonic cleaning). They may cause cracks to develop on the product and its parts,  
which might lead to reduced reliability or lifetime.  
Bending / twisting leads  
A lead (wire) may be bent at a minimum distance of twice the wire’s diameter plus 4 mm from  
the component head or housing. When bending ensure the wire is mechanically relieved at the  
component head or housing. The bending radius should be at least 0.75 mm.  
Soldering  
Use resin-type flux or non-activated flux.  
Insufficient preheating may cause ceramic cracks.  
Rapid cooling by dipping in solvent is not recommended.  
Complete removal of flux is recommended.

Mounting  
Ensure that no thermo-mechanical stress occurs due to production processes (curing or  
overmolding processes) when thermistors are sealed, potted or overmolded or during their  
subsequent operation. The maximum temperature of the thermistor must not be exceeded.  
Ensure that the materials used (sealing/potting compound and plastic material) are chemically  
neutral.  
Electrodes/contacts must not be scratched or damaged before/during/after the mounting  
process.  
Contacts and housing used for assembly with the thermistor must be clean before mounting.  
Ensure that adjacent materials are designed for operation at temperatures comparable to the  
surface temperature of the thermistor. Be sure that surrounding parts and materials can  
withstand the temperature.  
Avoid contamination of the thermistor surface during processing.  
The connections of sensors (e.g. cable end, wire end, plug terminal) may only be exposed to  
an environment with normal atmospheric conditions.  
Tensile forces on cables or leads must be avoided during mounting and operation.  
Bending or twisting of cables or leads directly on the thermistor body is not permissible.  
Avoid using chemical substances as mounting aids. It must be ensured that no water or other  
liquids enter the NTC thermistors (e.g. through plug terminals). In particular, water based  
substances (e.g. soap suds) must not be used as mounting aids for sensors.  
Operation  
Use thermistors only within the specified operating temperature range.  
Use thermistors only within the specified power range.  
Environmental conditions must not harm the thermistors. Only use the thermistors under  
normal atmospheric conditions or within the specified conditions.  
Contact of NTC thermistors with any liquids and solvents shall be prevented. It must be  
ensured that no water enters the NTC thermistors (e.g. through plug terminals). For  
measurement purposes (checking the specified resistance vs. temperature), the component  
must not be immersed in water but in suitable liquids (e.g. perfluoropolyethers such as Galden).  
Avoid dewing and condensation unless thermistor is specified for these conditions.  
Bending or twisting of cables and/or wires is not permissible during operation of the sensor in  
the application.  
Be sure to provide an appropriate fail-safe function to prevent secondary product damage  
caused by malfunction.  
This listing does not claim to be complete, but merely reflects the experience of EPCOS AG.

Important notes  
The following applies to all products named in this publication:  
1. Some parts of this publication contain statements about the suitability of our products for  
certain areas of application. These statements are based on our knowledge of typical re-  
quirements that are often placed on our products in the areas of application concerned. We  
nevertheless expressly point out that such statements cannot be regarded as binding  
statements about the suitability of our products for a particular customer application.  
As a rule, EPCOS is either unfamiliar with individual customer applications or less familiar  
with them than the customers themselves. For these reasons, it is always ultimately incum-  
bent on the customer to check and decide whether an EPCOS product with the properties de-  
scribed in the product specification is suitable for use in a particular customer application.  
2. We also point out that in individual cases, a malfunction of electronic components or  
failure before the end of their usual service life cannot be completely ruled out in the  
current state of the art, even if they are operated as specified. In customer applications  
requiring a very high level of operational safety and especially in customer applications in  
which the malfunction or failure of an electronic component could endanger human life or  
health (e.g. in accident prevention or lifesaving systems), it must therefore be ensured by  
means of suitable design of the customer application or other action taken by the customer  
(e.g. installation of protective circuitry or redundancy) that no injury or damage is sustained by  
third parties in the event of malfunction or failure of an electronic component.  
3. The warnings, cautions and product-specific notes must be observed.  
4. In order to satisfy certain technical requirements, some of the products described in this  
publication may contain substances subject to restrictions in certain jurisdictions (e.g.  
because they are classed as hazardous). Useful information on this will be found in our Ma-  
terial Data Sheets on the Internet (www.epcos.com/material). Should you have any more de-  
tailed questions, please contact our sales offices.  
5. We constantly strive to improve our products. Consequently, the products described in this  
publication may change from time to time. The same is true of the corresponding product  
specifications. Please check therefore to what extent product descriptions and specifications  
contained in this publication are still applicable before or when you place an order. We also  
reserve the right to discontinue production and delivery of products. Consequently, we  
cannot guarantee that all products named in this publication will always be available. The  
aforementioned does not apply in the case of individual agreements deviating from the fore-  
going for customer-specific products.  
6. Unless otherwise agreed in individual contracts, all orders are subject to the current ver-  
sion of the "General Terms of Delivery for Products and Services in the Electrical In-  
dustry" published by the German Electrical and Electronics Industry Association  
(ZVEI).
