PV12/PV37/PV36 Series Notice

c Notice (Operating and Storage Conditions)

c Notice (Rating)

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

the power depending 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.

c Notice (Soldering and Mounting)

Continued on the following page.

1. Soldering

(1) Soldering conditions

Refer to the temperature profile.

If the soldering conditions are not suitable,

e.g., excessive time and/or excessive

temperature, the trimmer potentiometer may

deviate from the specified characteristics.

(2) To minimize mechanical stress when adjusting,

the trimmer potentiometer should be mounted onto

the PCB without a gap.

(3) 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. Mounting

(1) Use the PCB hole to meet the pin of the trimmer

potentiometer. If the trimmer potentiometer

is installed into an insufficient PCB hole, the

trimmer potentimeter may be damaged by

mechanical stress.

(2) Do not apply excessive force, preferably 9.8N

max. (Ref. 1kgf) when the trimmer potentiometer

is mounted to the PCB.

3. Cleaning

Isopropyl alcohol and ethyl alcohol are applicable

solvents for cleaning. If you use any other types

of solvents, please consult with a Murata factory

representative prior to using.
