■ Notice (Soldering and Mounting)
1. Soldering
2. Mounting
(1) TZ03 series can be soldered by flow soldering
method and soldering iron. Do not use reflow
soldering method.
(1) Do not apply excessive force (preferably 5.0 N
[Ref: 500gf] max.), when the trimmer capacitor
is mounted on the PCB.
(2) Soldering condition
(2) 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.
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.
(3) The dimension of mounting hole should be Murata's
standard mounting hole used at flow soldering.
The amount of solder is critical. 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.
(4) 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 the 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.
(5) Our recommended chlorine content of string
solder is 0.5wt% max.
(3) Do not apply bending stress more than 10.0N
(Ref: 1kgf) after the trimmer capacitor has
been mounted on the PCB.
(4) Mount trimmer capacitor in contact with PCB.
(5) 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.
3. Cleaning
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.)
(6) Do not use water-soluble flux (for water cleaning).
To prevent the deterioration of trimmer
capacitor characteristics, apply flux only to
terminals.
■ Notice (Handling)
1. Use suitable screwdrivers that fit comfortably in
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.
driver slot.
(1) Recommended screwdriver for manual adjustment
MURATA: KMDR010
(2) Recommended screwdriver bit for automatic
adjustment
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.

■ Notice (Other)
Before using trimmer capacitor, please test after
assembly in your particular mass production system.
