PVZ2 Series Notice
s
Notice (Operating and Storage Conditions)
1. Store in temperatures of -10 to +40 deg. C and
relative humidity of 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. If you use the trimmer potentiometer in an
environment other than listed below, 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 sulfide 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 nor electric/magnetic fields
(6) Direct sea breeze
(7) Other variations of the above
1
s
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.
3. The maximum input current to a trimmer
potentiometer should not exceed (P/R)^1/2 or the
allowable wiper current, whichever is smaller.
4. If the trimmer potentiometer is used in DC and high
humidity conditions, please connect wiper (#2) for
plus and resistive element (#1 or #3) for minus.
s
Notice (Soldering and Mounting)
1. Soldering
(1) Reflow soldering and Soldering Iron are
available. Cannot be soldered using the flow
soldering method. If you use the flow soldering
method, the trimmer potentiometer may not
function.
(2) Use our standard land dimension. Excessive land
area causes displacement due to the effect of the
surface tension of the solder. Insufficient
land area leads to insufficient soldering
strength of the chip.
(3) Standard soldering condition
(a) Reflow soldering :
Refer to the standard temperature profile.
(b) Soldering iron:
>Temperature of tip 360 deg. C max.
>Soldering time
3 sec. max.
>Diameter
1mm 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 potentiometer may deviate from the
specified 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 reflow soldering.
Insufficient amounts of solder can lead to
insufficient soldering strength on PCB.
Excessive amounts of solder may cause bridging
between the terminals.
(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 4.9N
(Ref.; 500gf) max.), when the trimmer
potentiometer is mounted to the PCB.
(2) Do not warp and/or bend PC board to prevent
trimmer potentiometer from breakage.
(3) In chip placers, the recommended size of the
cylindrical pick-up nozzle should be outer
dimension 1.5-1.8mm dia. and inner dimension
1.3mm dia.
3. Cleaning
(1) In case there is flux on the resistive element,
clean sufficiently with cleaning solvents and
completely remove all residual flux.
(2) Isopropyl-alcohol and Ethyl-alcohol are

2. Don't apply more than 4.9N (Ref.; 500gf) of twist
and stress after mounting onto PCB to prevent
contact intermittence. If excessive force is
applied, the trimmer potentiometer may not
function.
3. Please use within the effective rotational angle.
The potentiometer does not have a mechanical stop
for over rotation. In cases out of effective
rotational angle, the trimmer potentiometer may
not function.
4. When using a lock paint to fix slot position,
please consult with a Murata factory representative
prior to using to prevent corrosion and contact
intermittence.

SMD Open Type and Test Methods
Specifications and SMD Sealed Type PVM4A_C01 Series Specifications and Test Methods
The tests and measurements should be conducted under the condition of 15 to 35°C of temperature, 25 to 75% of relative humidity and 86 to 106 kpa of
atmospheric pressure unless otherwise specified. If questionable results occur that have been measured in accordance with the above mentioned
conditions, the tests and measurements should be conducted under the condition of 25±2°C of temperature and, 45 to 55% of relative humidity and 86 to
106 kpa of atmospheric pressure.

Item
Test Methods
Measure total resistance between the resistance element and terminals (terminals #1 and #3) with the contact arm
positioned against a stop. The positioning of the contact arm and terminal should 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 should be used whenever a
subsequent total resistance measurement is made.

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 clock-
wise limit of mechanical travel and measure the resistance between the contact arm and the corresponding end ter-
minal. During this test, take suitable precautions to ensure that the rated current of the resistance element is not
exceeded.
Contact resistance variation should be measured with the measuring circuit shown below, or its equivalent. The
operating wiper should be rotated in both directions through 90% of the actual effective-electrical travel for a total of
6 cycles.
The rate of rotation of the operating wiper should be such that the wiper completes 1 count in determining whether or
not a contact resistance variation is observed at least twice in the same location. The test current should follow the
value given in Table-2 unless otherwise limited by the power rating.
