PVG3 Series Notice
s
Notice (Operating and Storage Conditions)
1. Store that the temperature is -10 to +40deg. C and
the relative humidity is 30-85%RH.
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. The trimmer potentiometer should not be used under
the following environmental conditions:
If you use the trimmer potentiometer in an
environment other these listed below, please
consult with Murata factory representative prior to
using.
(1) Corrosive gaseous atmosphere.
(Ex. Chlorine gas, Hydrogen sulfide gas, Ammonia
gas, Sulfuric acid gas, Nitric oxie gas, etc.)
(2) In liquid.
(Ex. Oil, Medical liquid, Organic solvent, etc.)
(3) Dusty/dirty atmosphere.
(4) Direct sunlight.
(5) Static voltage nor electric/magnetic fields.
(6) Direct sea breeze.
(7) Other variations of the above.
s
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.

s
Notice (Soldering and Mounting)
1. Soldering
(1) Standard soldering condition
(a) Reflow soldering :
Refer to the standard temperature profile.
(b) Soldering iron
Temperature of tip : 260deg. C max.
Soldering time
: 3sec. max.
Diameter of tip
: 2mm dia. max.
Wattage of iron
: 30W max.
Before using other soldering conditions more
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.
(2) Can not be soldered using the flow soldering
method. If you use the flow 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 insufficient, the required adhesive
strength cannot be obtained. If an excessive
amount of solder paste is applied, solder
bridging or flux overflow to the resistive
element surface can occur.
2. Mounting
(1) 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) Do not apply excessive force (preferable 4.9N
(Ref.; 500gf) max.), when the trimmer
potentiometer is mounted to the PCB.
(3) Do not warp and/or bend PC board to prevent
trimmer potentiometer from breakage.
(4) In chip placers, the size of the cylindrical
pick-up nozzle should be outer dimension
2.5-2.8mm dia. and inner dimension
2.0-2.5mm dia..
3. Cleaning
(1) Isopropyl-alcohol and Ethyl-alcohol are
applicable solvent for cleaning. If you use any
other types of solvents, please consult with
Murata factory representative prior to using.
(2) Less than 3 minutes of total cleaning time by
dipping, vapor and ultra-sonic method.
(3) In case of ultra-sonic cleaning method, cleaning
condition should be as follows.
(a) Power
: 600W (67lit.) max.
(b) Frequency : 28kHz
(c) Temperature : Ambient temperature
Due to ultra-sonic cleaning equipment peculiar
self resonance point and cleaning compatibility
usually depends on the jig construction and/or

* Recommended screwdriver bit for automatic
adjustment

We can supply above screwdrivers.
If you place order, please nominate Murata P/N.
2. Don't apply more than 9.8N (Ref.; 1kgf) of twist
and stress after mounted onto PCB to prevent
contact intermittence.
3. When adjusting with an adjustment tool, the applied
force to the adjustment screw should not exceed
4.9N (Ref.; 500gf). If excessive force is applied,
the trimmer potentiometer may not function due to
damage.
4. When using a lock paint to fix slot position,
please use adhesive resin without chlorine or
sulfur (Three-bond "1401series").
