Thick Film Chip Resistor

Chip resistors, which are available for surface mounting, are general passive

component which is useful for voltage drop, current controlling in circuit and

surface mounting is available.

Samsung electro-mechanics also manufactures a wide range of chip resistors

such as general, precision, trimmable and low ohms and so on.

Production is increasing with demand for small size & light weight of set product.

We provide ultra-small, high-reliability, high-stability resistors. We have

obtained ISO-9002/QS-9000 and ISO-14001 certification.

General Features

- Very small, thin, and light weight.

- Both flow and reflow soldering are applicable.

- Owing to the reduced lead inductance, the high frequency characteristic is excellent.

- Suitable size and packaging for surface mount assembly.

- Reel type and Bulk type Packaging are applicable.

Applications

- General purpose.

- Home Appliances

(DVD, Digital TV, Camcorder, VTR, Digital Camera, Audio, Tuner)

- For Computers & Communication Device.

(Notebook, Memory Module, Mobile, Network Equipment, etc)

● PACKAGING METHOD

Packaging protects the resistor from damage during the shipping or storage.

There are two types of packaging method ; one is "Reel" type, and the other is "Bulk" type.

APPLICATION MANUAL

● APPLICATIONS

Chip resistors are designed for general electronic devices such as home appliances, computer,

mobile communications, digital circuit, etc.

If you require our products with high reliability-performing at more than 125C or below -55C

for medical equipments, aircraft, high speed machines, military usage, and items that can

affect human life or if you need to use in specific conditions (corrosive gas atmosphere),

please contact us beforehand.

▶ Normal Operation temperature ranges(℃) as follows.

- 1608, 2012, 3216(general, precision) : -55℃ ~ + 155℃

- Others (rectangular, array, trimmable) : -55℃ ~ + 125℃

▶ Although resistor body is coated, sharp excessive impact should be avoided to prevent

damages and adverse effects on characteristics(resistor value, open circuited, T.C.R.).

● STORAGE

To maintain proper quality of chip components, the following precautions are required for

storage environment, method and period.

▶ Storage Environment

- Chip components may be deformed, if the temperature of packaged components exceeds

40℃.

- Do not store where the soldering properties can be deteriorated by harmful gas such as

sulphurous gas, chlorine gas, etc.

- Bulk packed chip components should be used as soon as the seal is opened, thus

preventing the solderability from deteriorating.

- The remaining unused chips should be put in the original bag and sealed again or store in

a desiccator containing a desiccating agent.

▶ Storage Time Period

- Stored chip components should be used within 6 months after receiving the components.

If 6 months or more have elapsed, please check the solderability before actually using.

● MOUNTING

Proper nozzle height must be given attention so as not to give excessive pressure on the

chip during mounting on the PCB.

(Excessive pressure may cause exterior damage, change in resistance, circuit open, etc.)

● SOLDERING

Our products have Ag electrodes protected by double layer.

▶ 1st Ni Coating

- This prevents Ag electrode from leaching and enhance the bonding with Sn

▶ 2nd Sn Coating

- This is made of Sn 100% with melting point 232℃ to prevent it from melting when solder

cream melts, and to enhance the bonding.

- Commercial solder creams are made of Sn-3.0Ag-0.5Cu with melting point 217℃.

● CLEANING

If rosin flux is used, cleaning usually is unnecessary. When strongly activated flux is used, chlorine in the

flux may dissolve into some types of cleaning fluids, thereby affecting the chip capacitors.

This means that the cleaning fluid must be carefully selected, and should always be new.

● CAUTION FOR CHIP RESISTOR SEPERATION FROM PCB

Chip resistor installation on PCB is similar phenomenon as chocolate chip on top of cake.

PCB has enough flexibility on outer force but Chip resistor can be defected without any bending.

(By chip resistor use of Ceramic, solder, metal)

Therefore, when separate from Chip resistor on PCB, be ware of any crack of chip

● OTHERS

▶ Manual work

Manual soldering can pose a great risk of creating thermal cracks in chip resistors.

The hot soldering iron tip comes into direct contact with the end terminations, an operator's

carelessness may cause the tip of the soldering iron to come into direct contact with the

ceramic body of the resistors.

Therefore the soldering iron must be handled carefully, and close attention must be paid

to the selection of the soldering iron tip and to temperature control of the tip.

▶ Do not use more than rated voltage.(check the contents on the file)

NOTICE

● RECOMMENDED USAGE OF THE RESISTOR

▶ Flow Soldering

After mounting the resistor to PCB with paste, dip the PCB into solder bath. <Fig 15>

▶Reflow Soldering

After printing solder creams on PCB, place the resistor on the solder cream.

Then heat the PCB. <Fig 16>

● CAUTION

▶ Storage condition

Please make sure to keep the storage conditions.

* Temperature : 5℃∼40℃, * Humidity : 20%RH ∼ 70%RH

▶ Damage control

Please handle with care to prevent damaging the resistor.

Specially, the excessive nozzle height of SMD or the extreme pressure with tweezers.

▶ Leaching prevention

It is important to keep the soldering conditions to prevent Ag leaching in Flow soldering.
