■ Notice (Operating and Storage Conditions)

1. Store that the temperature is -10 to +40deg. C and

the relative humidity is 30-85%RH.

using.

(1) Corrosive gaseous atmosphere.

(Ex. Chlorine gas, Hydrogen sulfide gas, Ammonia

gas, Sulfuric acid gas, Nitric oxie gas, etc.)

(2) In liquid.

2. Do not store in or near corrosive gases.

3. Use within six months after delivery.

4. Open the package just before using.

5. Do not store under direct sunlight.

(Ex. Oil, Medical liquid, Organic solvent, etc.)

(3) Dusty/dirty atmosphere.

6. The trimmer potentiometer should not be used under

the following environmental conditions:

(4) Direct sunlight.

If you use the trimmer potentiometer in an

environment other these listed below, please

consult with Murata factory representative prior to

(5) Static voltage nor electric/magnetic fields.

(6) Direct sea breeze.

(7) Other variations of the above.

■ Notice (Rating)

1. When using with partial load (rheostat), minimize

the power depend on the resistance value.

2. The maximum input voltage to a trimmer

potentiometer should not exceed (P•R)^1/2 or the

maximum operating voltage, whichever is smaller.

3. The maximum input current to a trimmer

potentiometer should not exceed (P/R)^1/2 or the

allowable wiper current, whichever is smaller.

■ Notice (Soldering and Mounting)

1. Soldering

Insufficient amounts of solder can lead to

insufficient soldering strength on PCB.

Excessive amounts of solder may cause the

bridging between the terminals.

(1) Can be soldered by reflow soldering method, flow

soldering method, and soldering iron. (Incase

of flow soldering, it is necessary to clean

after soldering.)

(5) The soldering iron should not come in contact

with the case of the trimmer potentiometer. If

such contact does occur, the trimmer

potentiometer may be damaged.

(2) Use our standard land dimension. Excessive land

area causes displacement due to effect of the

surface tension of the solder. Insufficient

land area leads to insufficient soldering

strength of the chip.

2. Mounting

(1) Do not apply excessive force (preferable 9.8N

(Ref.; 1kgf) max.), when the trimmer

potentiometer is mounted to the PCB.

(2) Do not warp and/or bend PC board to prevent

trimmer potentiometer from breakage.

(3) In chip placers, the recommended size of the

cylindrical pick-up nozzle should be outer

dimension 4.0mm dia. and inner dimension 2.0mm

dia..

(3) Standard soldering condition

(a) Reflow and flow soldering :

Refer to the standard temperature profile.

(b) Soldering iron:

>Temperature of tip 260deg.C max.

>Soldering time

>Diameter

3sec. max.

2mm dia. max.

30W max.

>Wattage of iron

Before using other soldering conditions than

those listed above, please consult with Murata

factory representative prior to using. If the

soldering conditions are not suitable, e. g.,

excessive time and/or excessive temperature,

the trimmer potentiometer may deviate from the

specified characteristics.

3. Cleaning

(1) Isopropyl alcohol and Ethyl alcohol are

available material for cleaning.

For other materials, please consult with Murata

factory representative prior to using.

(2) The total cleaning time by cold dipping method

shall be less than 5 minutes.

(4) Apply the appropriate amount of solder paste.

The thickness of solder paste should be printed

from 100micro m to 150micro m and the dimension

of land pattern should be used Murata's

wise limit of mechanical travel and measure the resistance between the contact arm and the corresponding end ter-

minal. During this test, take suitable precautions to ensure that the rated current of the resistance element is not

exceeded.
