■ Notice (Soldering and Mounting)
1. Soldering
(7) Do not use water-soluble flux (for water
cleaning). To prevent the deterioration of
trimmer capacitor characteristics, apply flux
only to terminals.
(1) Can be soldered by reflow soldering method, flow
soldering method, and soldering iron.
(2) Soldering condition
Refer to the temperature profile.
2. Mounting
If the soldering conditions are not suitable, e.g.,
excessive time and/or excessive temperature, the
trimmer capacitor may deviate from the specified
characteristics.
(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.
(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
should 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.
(3) 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.
(4) 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]
Isopropyl alcohol and Ethyl alcohol are available
material for cleaning. If you use any other types
of solvents, please evaluate performance by
your set. Moreover, please confirm no damage for
trimmer capacitor after cleaning by your conditions.
4. Other
Note the polarity of the trimmer capacitor to
minimize influence by stray capacitance.
(Refer to the dimensions concerning the polarity.)
(a) Solder paste: 0.2wt% max.
(b) String solder: 0.5wt% max.
■ Notice (Handling)
1. Use suitable screwdrivers that fit comfortably in
3. Do not apply adhesive, lock paints, or any other
substances to the trimmer capacitor to secure the
rotor position. They may cause corrosion or
electrical contact problems.
driver slot.

(1) Recommended screwdriver for manual adjustment
MURATA: KMDR010
(2) Recommended screwdriver bit for automatic
adjustment
4. Do not break the cover film before the completion
of PCB mounting, soldering, and cleaning.
5. Do not clean the trimmer capacitor after the cover
film has been broken.
MURATA: KMBT010
2. When adjusting with a screwdriver, do not apply
excessive force (preferably 1.0 N [Ref: 100gf] max.)
to minimize capacitance drift. If excessive force
is applied to the screwdriver slot, it may cause
deformation of the products.
6. To break the cover film, first turn the screwdriver
more than 360 deg., and set the capacitance value.
(Only inserting the screwdriver cannot break the
cover film.)
■ Notice (Other)
Before using trimmer capacitor, please test after
assembly in your particular mass production system.
