PVM4 Series Notice
c Notice (Operating and Storage Conditions)
1. Store in temperatures of -10 to +40°C and
relative humidity of 30-85%.
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.
6. If you use the trimmer potentiometer in an
environment other than listed at right, please
consult with a Murata factory representative prior
to using.
The trimmer potentiometer should not be used under
the following environmental conditions:
(1) Corrosive gaseous atmosphere
(Ex. Chlorine gas, Hydrogen sul?de gas, Ammonia
gas, Sulfuric acid gas, Nitric oxide gas, etc.)
(2) In liquid
(Ex. Oil, Medical liquid, Organic solvent, etc.)
(3) Dusty/dirty atmosphere
(4) Direct sunlight
(5) Static voltage or electric/magnetic ?elds
(6) Direct sea breeze
(7) Other variations of the above
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)
1. Soldering
(1) Can be soldered by re?ow soldering method, ?ow
soldering method, and soldering iron.
(2) Use our standard land dimension. Excessive land
area causes displacement due to the effect of
the surface tension of the solder. Insuf?cient
land area leads to insuf?cient soldering
strength of the chip.
(3) Soldering conditions
Refer to the temperature pro?le.
If the soldering conditions are not suitable,
e.g., excessive time and/or excessive temperature,
the trimmer potentiometer may deviate from the
speci?ed characteristics.
(4) Apply the appropriate amount of solder paste.
The thickness of solder paste should be printed
from 100 micro m to 150 micro m and the
dimension of land pattern used should be Murata's
standard land pattern at re?ow 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. Mounting
(1) Do not apply excessive force, preferably 9.8N
max. (Ref. 1kgf) when the trimmer potentiometer
is mounted to the PCB.
(2) Do not warp and/or bend the PC board to protect
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. Cleaning
Isopropyl alcohol and ethyl alcohol are available
materials for cleaning.
For other materials, please consult with a Murata
factory representative prior to using.
4
Insuf?cient amounts of solder can lead to
insuf?cient soldering strength on PCB.
Excessive amounts of solder may cause bridging
between the terminals.
