PVZ2/PVA2 Series Notice
■
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
■
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. 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.
(PVZ Series only)
■
Notice (Soldering and Mounting)
1. Soldering
(1) Reflow soldering method and soldering iron are
available. Cannot be soldered using the flow
soldering method (dipping). 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) Soldering condition
Refer to the temperature profile.
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
applicable solvents for cleaning. If you use any
other types of solvents, please evaluate
performance by your product.

Notice (Handling)
1. Use suitable screwdrivers that fit comfortably in
driver slot. We recommend the screwdriver below.
* Recommended screwdriver for manual adjustment
Murata P/N: KMDR190
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 trimmer 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 or
cover the rotor, please evaluate performance by
your product. Lock paint may cause corrosion or
electrical contact problems.
■
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 cannot guarantee trimmer potentiometer
integrity when used under conditions other than
those specified in this document.
