Trimmer Potentiometers
SMD Open Type 3mm Size PVZ3/PVS3/PVA3 Series
PVZ3 Series
s Features
1. Excellent solderability characteristics are
achieved via special plating techniques on each
termination.
2. Specially designed substrate prevents wicking of
flux onto the top of the part body.
3. Enlarged bottom termination enhance soldering
strength while reducing the nocessary land area
required promoting high-density PCB mounting.
4. Funnel shaped adjustment slot allows for in-process
automatic adjustment.
5. Flat surface is provided for smooth pick and place.
(PVZ3K only)
6. Heat-Resistant type is available. (PVZ3AxxxB01)
7. The standard position of driver plate is adjusted
at the center normally, but another position is
also available.
8. This product meets Pb-free.
s Applications
1. Optical pick up
3. CD players
5. Motor
7. Car stereos
9. Headphone stereos
2. Cordless telephones
4. FDD

PVZ3/PVS3/PVA3 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.
2 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.
4. If the trimmer potentiometer is used in DC and high
humidity condition, please connect wiper (#2) for
plus and resistive element (#1 or #3) for minus.
s Notice (Soldering and Mounting)
1. Soldering
(1) Standard soldering condition
(a)Reflow soldering :
Refer to the standard temperature profile.
(b)Soldering iron:
*PVZ3AxxxA01, PVZ3KxxxA01, PVA3, PVS3 series
>Temperature of tip 260deg. C max.
>Soldering time 3sec. max.
>Diameter
1mm max.
>Wattage of iron 30W max.
*PVZ3AxxxB01, PVZ3KxxxB01 series
>Temperature of tip 310deg. C max.
>Soldering time 5sec. 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.
(2) Flow slodering is available for PVA3 series.
For PVZ3A, PVZ3K and PVS3, do not use flow
soldering method (dipping).
If you use the flow soldering method, the
trimmer potentiometer may not function.
16
(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.
The thickness of solder paste should be printed
from 150micro m to 200micro m (PVZ3K series
should be printed from 100micro m to 150micro m)
and the dimension of land pattern should be
used 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 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 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 recommended size of the
cylindrical pick-up nozzle should be outer

3. Cleaning
(1) In case there is flux on the resistive element,
clean sufficiently by cleaning solvents and
remove all residual flux perfectly.
(2) 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.
