Note
The self-heating of a thermistor during operation depends on the load applied and the
applicable dissipation factor.
When loaded with maximum allowable current/power and the specified dissipation factor is
taken as a basis, the NTC thermistor may reach a mean temperature of up to 250 °C.
The heat developed during operation will also be dissipated through the lead wires. So the
contact areas, too, may become quite hot at maximum load.
When mounting NTC thermistors you have to ensure that there is an adequate distance
between the thermistor and all parts which are sensitive to heat or combustible.

Application notes
The following two important aspects for determining the right NTC inrush current limiter are
excerpted from the chapter "Application notes" in the "NTC Inrush Current Limiters,
Data book 2012". The complete application note can be downloaded from
www.epcos.com/ntcicl_appnotes.
1.4 Load derating
The power handling capability of an NTC thermistor cannot be fully utilized over the entire temper-
ature range. For circuit dimensioning the derating curve given below provides information on the
extent to which the current must be reduced at a certain ambient temperature (TA).
Derating curve for types S237, P11 and P13

TA = Ambient temperature > 65 °C
Tmax = 170 °C
The Imax values specified in the data sheets denote the maximum permissible continuous current
(DC or RMS values for sine-shaped AC) in the temperature range 0 °C to 65 °C.
1.6 Maximum permissible capacitance
The currents during turn-on are much higher than the rated currents during continuous operation.
To test the effects of these current surges EPCOS uses the following standard procedure accord-
ing to IEC 60539-1:

VNTC
The capacitor Ctest is discharged via the series resistor RS and the NTC inrush current limiter. The
load voltage is chosen such that the voltage applied to the thermistor at the start of discharge is
VNTC = 375 V (corresponds to (230 V + ∆V) ꢁ ꢂ2).

Robustness of terminations
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.

P13
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.
Twisting of leads
The twisting (torsion) by 180° of a lead bent by 90° is permissible at 6 mm from the bottom of the
thermistor body.
3
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.
4
Cleaning
If cleaning is necessary, mild cleaning agents such as ethyl alcohol and cleaning gasoline are
recommended. Cleaning agents based on water are not allowed. Ultrasonic cleaning methods are
permissible.
5
Storage
In order to maintain their solderability, thermistors must be stored in a non-corrosive atmosphere.
Humidity, temperature and container materials are critical factors.
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
Max. relative humidity (without condensation):
<95%, maximum 30 days per annum
Solder the thermistors listed in this data book after shipment from EPCOS within the time speci-
fied:
Leaded components:
24 months

Cautions and warnings
General
See "Important notes" on page 2.
Storage
Store thermistors only in original packaging. Do not open the package before storage.
Storage conditions in original packaging: storage temperature ꢀ25 °C ... +45 °C, relative
humidity ≤75% annual mean, maximum 95%, dew precipitation is inadmissible.
Avoid contamination of thermistors surface during storage, handling and processing.
Avoid storage of thermistor in harmful environments like corrosive gases (SOx, Cl etc).
Solder thermistors after shipment from EPCOS within the time specified:
ꢀ
Leaded components: 24 months
Handling
NTC inrush current limiters must not be dropped. Chip-offs must not be caused during handling
of NTC inrush current limiters.
Components must not be touched with bare hands. Gloves are recommended.
Avoid contamination of thermistor surface during handling.
In case of exposure of the NTC inrush current limiters to water, electrolytes or other aggressive
media, these media can penetrate the coating and reach the surface of the ceramic. Low-ohmic
or high-ohmic behavior may occur due to the formation of an electrolyte with metals
(silver/lead/tin from metallization or solder). Low-ohmic behavior is caused by electrochemical
migration, high-ohmic behavior by dissolving of the electrode. In either case, the functionality of
the NTC inrush current limiters can not be assured.
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.
Twisting (torsion) by 180° of a lead bent by 90° is permissible at 6 mm from the bottom of the
thermistor body.
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.

P13
Mounting
When NTC inrush current limiters are encapsulated with sealing material or overmolded with
plastic material, the precautions given in chapter “Mounting instructions”, “Sealing and potting”
must be observed.
Electrode must not be scratched before/during/after the mounting process.
Contacts and housings used for assembly with thermistor have to be clean before mounting.
During operation, the inrush current limiters surface temperature can be very high. Ensure that
adjacent components are placed at a sufficient distance from the thermistor to allow for proper
cooling of the NTC inrush current limiters.
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 this temperature.
Make sure that inrush current limiters are adequately ventilated to avoid overheating.
Avoid contamination of thermistor surface during processing.
Operation
Use NTC inrush current limiters only within the specified operating temperature range.
Use NTC inrush current limiters only within the specified voltage and current ranges.
Environmental conditions must not harm the NTC inrush current limiters. Use NTC inrush
current limiters only in normal atmospheric conditions.
Contact of NTC inrush current limiters with any liquids and solvents should be prevented. It
must be ensured that no water enters the NTC inrush current limiters (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. Galden).
In case of exposure of the NTC inrush current limiters to water, electrolytes or other aggressive
media, these media can penetrate the coating and reach the surface of the ceramic. Low-ohmic
or high-ohmic behavior may occur due to the formation of an electrolyte with metals
(silver/lead/tin from metallization or solder). Low-ohmic behavior is caused by electrochemical
migration, high-ohmic behavior by dissolving of the electrode. In either case, the functionality of
the NTC inrush current limiters can not be assured.
Be sure to provide an appropriate fail-safe function to prevent secondary product damage
caused by malfunction (e.g. use a metal oxide varistor for limitation of overvoltage condition).
This listing does not claim to be complete, but merely reflects the experience of EPCOS AG.
Display of ordering codes for EPCOS products
The ordering code for one and the same EPCOS product can be represented differently in data
sheets, data books, other publications, on the EPCOS website, or in order-related documents
such as shipping notes, order confirmations and product labels. The varying representations of
the ordering codes are due to different processes employed and do not affect the
specifications of the respective products. Detailed information can be found on the Internet

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-
