PVG3 Series Notice

!Note

• Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.

• This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please approve our product specifications or transact the approval sheet for product specifications before ordering.

■ 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.

■ Notice (Soldering and Mounting)

1. Soldering

(1) Standard soldering condition

(a) Reflow soldering :

Refer to the standard temperature profile.

(b) Soldering iron

Temperature of tip : 400 deg. C max.

Soldering time : 3 sec. max.

Diameter of tip : 2mm dia. max.

Wattage of iron : 30W max.

Before using other soldering conditions more

than those listed above, please consult with a

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) Cannot 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) Apply the appropriate amount of solder paste.

If the amount of solder paste applied to the

land is insufficient, the required adhesive

strength cannot be obtained. If an excessive

amount of solder paste is applied, solder

bridging or flux overflow to the resistive

element surface can occur.

2. Mounting

(1) 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.

(2) Do not apply excessive force (preferably 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 size of the cylindrical

pick-up nozzle should be outer dimension

2.5-3.0mm dia. and inner dimension

2.0-2.5mm dia..

3. Cleaning

(1) Isopropyl-alcohol and Ethyl-alcohol are

applicable solvents for cleaning. If you use any

other types of solvents, please consult with a

Murata factory representative prior to using.

(2) Less than 3 minutes of total cleaning time by

dipping, vapor and ultra-sonic method.

(3) In case of ultra-sonic cleaning method, cleaning

conditions should be as follows.

(a) Power: 600W (67lit.) max.

(b) Frequency: 28kHz

Due to ultra-sonic cleaning equipment's peculiar

self-resonance point and that cleaning

compatibility usually depends on the jig

as the depth of immersion, please check the

cleaning equipment to determine the suitable

conditions. If the condition is not suitable,

■ Notice (Handling)

1. Use suitable screwdrivers that fit comfortably in

driver slot.

* Recommended screwdriver for manual adjustment

(Murata P/N : KMDR070)

* Recommended screwdriver bit for automatic

adjustment

TORAY INDUSTRIES, INC. : JB-2225

(Mutata P/N : KMBT070)

We can supply the screwdrivers above.

If you place order, please specify the Murata P/N.

2. Don't apply more than 9.8N (Ref.; 1kgf) of twist

and stress after mounting onto PCB to prevent

contact intermittence.

3. When adjusting with an adjustment tool, the applied

force to the adjustment screw should not exceed

4.9N (Ref.; 500gf). If excessive force is applied,

the trimmer potentiometer may not function due to

damage.

4. When using a lock paint to fix slot position,

please use adhesive resin without chlorine or

sulfur (Three-bond "1401 series").

■ 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.

Item Test Methods

Total Resistance1

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 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 for all subsequent total resistance measurements.

Specifications and Test Methods

Residual Resistance2

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.

Figure 1: CRV measuring circuit

Contact resistance variation should be measured with the measuring circuit shown in Figure 1, or its equivalent. The

adjustment rotor (screw) should 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 should 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) should be such that the adjustment rotor (screw) completes 1 cycle for 5 seconds minimum

to 2 minutes maximum. The test current used should follow the value given in Table 2 unless otherwise limited by

power rating.

The wiper should be set at approximately 40% of the actual effective-electrical rotational angle (number of turns). An

adequate DC test potential should be applied between terminal #1 and terminal #3. The voltage between terminal #1

and terminal #3, and the voltage between terminal #1 and terminal #2, should be measured and applied to the

following formula.
