!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) Flow soldering :
>Pre-heating temp. 80-100 deg. C
>Soldering temp. 260 deg. C max.
>Soldering time 3 sec. max.
(b) Soldering iron :
>Temperature of tip 300 deg. C max.
>Soldering time 3 sec. max.
>Wattage of iron 40W 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) To minimize mechanical stress when adjusting,
the trimmer potentiometer should be mounted onto
PCB without gap.
(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.
2. Mounting
(1) Use PCB hole to meet the pin of the trimmer
potentiometer. If the trimmer potentiometer
installs into insufficient PCB hole, the
trimmer potentimeter may be damaged by
mechanical stress.
(2) Do not apply excessive force (preferably 9.8N
(Ref.; 1kgf) max.), when the trimmer
potentiometer is mounted to the PCB.
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) The total cleaning time by cold dipping, vapor
and ultrasonic washing (conditions as below)
method should be less than 3 minutes.
(3) For ultra-sonic cleaning, the available
condition is as follows.
>Power: 600W (67 liter) max.
>Frequency: 28kHz
>Temperature: Ambient temperature
Due to the ultra-sonic cleaning equipment's
peculiar self-resonance point and that the
cleaning compatibility usually depends on the jig
construction and/or the cleaning condition such
as the depth of immersion, please check the
cleaning equipment to determine the suitable
conditions.
If the trimmer potentiometer is cleaned by
other conditions, the trimmer potentiometer may
be damaged.
