■ Notice (Storage and Operating Condition)
1. Do not use the trimmer capacitor under atmosphere
of RTV silicone rubber (Room Temperature
Vulcanizing Silicone Rubber) except Acetone
liberating silicone sealant.
6. Do not use the trimmer capacitor under the
conditions listed below.
(1) Corrosive gasses atmosphere
(ex. Chlorine gas, Hydrogen sulfide gas,
Ammonia gas, Sulfuric acid gas, Nitric oxide gas,
etc.)
2. Before using trimmer capacitor, please store under
the condition of -10 to +40 degree C and 30 to
85%RH.
(2) In liquid (ex. water, oil, medical liquid,
organic solvent, etc.)
3. Do not store in or near corrosive gasses.
4. Use within 6 months of delivery.
(3) Dusty / dirty atmosphere
5. Do not store under direct sunlight.
(4) Direct sunlight
(5) Static voltage nor electric/magnetic fields
(6) Direct sea breeze
(7) Other variations of the above
■ Notice (Soldering and Mounting)
1. Soldering
(3) Use the suitable PCB holes which are the same
pitch as the terminal of the trimmer capacitor.
If it would not fit with the terminal, the
excessive stress would be applied to the
terminal and the trimmer capacitor may deviate
from the specified characteristics (Terminal
shape C and D).
(1) Can be soldered by reflow soldering method, flow
soldering method, and soldering iron.
(2) Soldering condition
Refer to the temperature profile.
If the soldering conditions are not suitable, e.g.,
excessive time and/or excessive temperature, the
trimmer capacitor may deviate from the specified
characteristics.
(4) Do not apply bending stress more than 10.0N
(Ref: 1kgf) after the trimmer capacitor has
been mounted on the PCB (Terminal shape C and D).
(5) Mount trimmer capacitor in contact with PCB
(Terminal shape C and D).
(3) The amount of solder is critical.
(4) The thickness of solder paste should be printed
from 150 micro m to 200 micro m and the dimension
of land pattern should be Murata's standard land
pattern used 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
or contact failure due to flux wicking up.
(5) When using soldering iron, the string solder
shall be applied to the lower part of the
terminal only. Do not apply flux except to the
terminals. Excessive amounts of solder and/or
applying solder to the upper part of the
terminal may cause fixed rotor or contact failure
due to flux invasion into the movable part and/or
the contact point. The soldering iron should not
come in contact with the plastic case of the
trimmer capacitor. If such contact does occur,
the trimmer capacitor may be damaged.
(6) Our recommended chlorine content of solder is
as follows.
(6) In case of bending the terminals, do not apply
excessive force to the body of the product and
prevent the terminal fixing part from damaging.
(7) Use the suitable dimension of the pick-up nozzle.
> Without cover film type
- External dimensions of 4.5x4.0mm and
2.5mm bore diameter.
> With cover film type
- 4.0mm external diameter and 2.0mm bore
diameter.
3. Cleaning [with cover film type]
7
(1) Isopropyl alcohol and Ethyl alcohol are
available material for cleaning. Water group
material like Pinealpha, Cleanthru cannot be
used. For other materials, please consult with
Murata factory representative prior to using.
(2) The total cleaning time by dipping, vapor and
ultra-sonic method should be less than 2 minutes.
For ultra-sonic cleaning, the available
condition is as follows.
(a) Solder paste: 0.2wt% max.
(b) String solder: 0.5wt% max.
> Cleaning time: 1 min. max.
(7) Do not use water-soluble flux (for water
cleaning). To prevent the deterioration of
trimmer capacitor characteristics, apply flux
only to terminals.
> Power: 20W/liter max.
> Frequency: 20 - 60kHz
> 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
2. Mounting
(1) Do not apply excessive force (preferably 5.0N
[Ref: 500gf] max.), when the trimmer capacitor
is mounted on the PCB.
(2) Do not warp and/or bend PCB to prevent trimmer
capacitor from breakage.
