1. Store that the temperature is -10 to +40deg. C and
the relative humidity is 30-85%RH.

(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
