PVG5/PV01 Series Notice
■ 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.
■ 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
(1) Standard soldering condition
(a) Reflow and flow soldering :
Refer to the standard temperature profile.
(b) Soldering iron :
>Temperature of tip 260 deg.C max.
>Soldering time
3sec. max.
>Diameter
2mm dia. max.
>Wattage of iron
30W max.
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 capacitor 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) Insufficient amounts of solder can lead to
insufficient soldering strength on PCB.
Excessive amounts of solder may cause the
bridging between the terminals.
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 9.8N
(Ref.; 1kgf) 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 recommended size of the
cylindrical pick-up nozzle should be outer
dimension 4.0mm dia. and inner dimension 2.0mm
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) The total cleaning time by cold dipping, vaper
and ultrasonic washing (conditions as below)
method shall be less than 3 minutes.
(3) For ultra-sonic cleaning, the available
condition is as follows.
>Power
: 600W (67liter) max.
>Frequency
: 28kHz
>Temperature : Ambient temperature
Due to the ultra-sonic cleaning equipment
peculiar self resonance point and the cleaning
compatibility usually depends on the jig
construction and/or the cleaning condition such
as the depth of immersion, please check the

We can supply above screwdrivers.
If you place order, please nominate Murata P/N.
■ Notice (Other)
1. Please make sure that your product has been
evaluated and confirmed against your
specifications when our product is mounted to your
product.
2. Murata connot guarantee trimmer potentiometer
integrity when used under conditions other than
those specified in this document.
38
2. Don't apply more than 9.8N (Ref.; 1kgf) of twist
and stress after mounted onto PCB to prevent
contact intermittence. If excessive force is
applied, the trimmer potentiometer may not
function.
3. When adjusting with a screwdriver, do not apply
excessive force (preferable 4.9N (Ref; 500gf) max.)
4. When using a lock paint to fix slot position,
please use adhesive resin without chlorine or
sulfur (Three-bond "1401series").

Methods
The following describes trimmer potentiometer testing conducted by Murata Manufacturing Co., Ltd. in accordance with MIL-R-22097 (Military specification
for variable resistors, non-wirewound) and MIL-STD-202 (Test methods for electronic and electrical component parts).

Item
Test Methods
Measure total resistance between the resistance element and terminals (#1 and #3) with the contact arm positioned
against a stop. The positioning of the contact arm and terminal shall be the same for subsequent total resistance
measurements on the same device. Use the test voltage specified in Table-1 for total resistance measurements.
This voltage shall be used for all subsequent total resistance measurements.

Residual Resistance
Position the contact arm at the extreme counterclockwise limit of mechanical travel and measure the resistance
between the contact arm and the corresponding end terminal. Then, position the contact arm at the extreme clockwise limit of mechanical travel and measure the resistance between the contact arm and the corresponding end terminal. During this test, take suitable precautions to ensure that the rated current of the resistance element is not
exceeded.
Contact resistance variation shall be measured with the measuring circuit shown in Figure-1, or its equivalent. The
adjustment rotor (screw) shall be rotated in both directions through 90% of the actual effective-electrical rotational
angle(number of turns) for a total of 6 cycles. Only the last 3 cycles shall count in determining whether or not a contact resistance variation is observed at least twice in the same location, exclusive of the roll-on or roll-off points
where the contact arm moves from the termination, on or off, the resistance element. The rate of rotation of the
adjustment rotor (screw) shall be such that the adjustment rotor (screw) completes 1 cycle for 5 seconds minimum to
2 minutes maximum. The test current used shall follow the value given in Table-2 unless otherwise limited by power
rating.
