PVG3 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
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
to using.
(5) Static voltage or electric/magnetic ?elds
(6) Direct sea breeze
3
(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) 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.
(2) This product cannot be soldered using the ?ow
soldering method. If you use the ?ow soldering
method, the trimmer potentiometer may not
function.
(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.
(4) Apply the appropriate amount of solder paste.
If the amount of solder paste applied to the
land is insuf?cient, the required adhesive
strength cannot be obtained. If an excessive
amount of solder paste is applied, solder
2. Mounting
(1) 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.
(2) Do not apply excessive force, preferably 4.9N
max. (Ref. 500gf) when the trimmer potentiometer
is mounted to the PCB.
(3) Do not warp and/or bend the PC board to protect
trimmer potentiometer from breakage.
(4) In chip placers, the size of the cylindrical
pick-up nozzle should be outer dimension
2.5-3.0mm dia. and inner dimension
2.0-2.5mm dia.
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.
bridging or ?ux over?ow to the resistive
element surface can occur.
