PVZ2 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. 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.

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.

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.

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.

No.

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.
