(4)The thickness of solder paste should be printed
from 100µm to 150µm and the dimension of land
pattern should be used Murata's standard land
pattern at reflow soldering. Insufficient amounts
of solder can lead to insufficient soldering
as follows.
(a)Solder paste: 0.2wt% max.
(b)String solder: 0.5wt% max.
(7)Do not use water-soluble flux (for water cleaning).
To prevent the deterioration of trimmer capacitor
characteristics, apply flux only to terminals.
2. Mounting
strength on PCB. Excessive amounts of solder may
cause the bridging between the terminals or the
contact failure due to flux wicking up.
(1)Do not apply excessive force (preferable 5.0N
(Ref.; 500gf)max.), when the trimmer capacitor is
mounted on the PCB.
(5)When using soldering iron, the diameter of the
string solder shall be less than 0.5mm. The string
solder shall be applied to the lower part of the
terminal only and do not apply flux except the
terminals. Excessive amounts of solder and/or
applying solder to the upper part of the terminal
may cause fixed metal 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 monolithic stator of the
trimmer capacitor. If such contact does occur, the
trimmer capacitor may be damaged.
(2)Do not warp and/or bend PCB to prevent trimmer
capacitor from breakage.
(3)Use the suitable dimension of the pick-up nozzle.
(1.8mm external diameter and 1.3mm bore diameter.)
3. Cleaning

Can not be cleaned because of open construction.
4. Other
Note the polarity of the trimmer capacitor to
minimize influence by stray capacitance.
(Refer to the dimensions concerning the polarity.)
(6)Our recommendable chlorine content of solder is
■ Notice (Handling)
1. Use suitable screwdrivers that fit comfortably in
excessive force(preferable 1.0N(Ref;100gf) max.) to
minimize capacitance drift. If excessive force
applied to the screwdriver slot, it may cause
deformation of the products.
driver slot.

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)
1. Before using trimmer capacitor, please test after
assembly in your particular mass production system.
2. MURATA cannot guarantee trimmer capacitor integrity
when used under conditions other than those
specified in this document.
3. We have an application manual for trimmer capacitor.
