Notice for Soldering and Adjusting

Technical Note of Trimmer Capacitor

- The points of soldering

(1) Please use Murata’s standard land pattern.

TZC3 Land Pattern

By bigger land pattern, it will be excessive amount of solder and
may cause contact failure due to flux wicking up.
In case of TZC3 type, when solder flows into the staking part of center axis in a bottom,
the center axis might be fixed and there is a possibility of trouble for capacitance adjustment.

(2) Please solder by the appropriate solder amount. 
      When you solder or rework with iron, please be careful of solder amount.

(3) Please do not solder by heated air blower. 
      There is a possibility that resin part is deformed especially TZC3 type use resin material.

When deviating from the above, the following defect might be caused.
(Trouble case of TZC3 type.)

TZC3 Trouble Case

The points of adjusting

(1)Please use suitable screwdrivers that fit comfortably in driver slot.
If you use uncomfortable screwdriver that does not fit in driver slot or
the tip of screwdriver is broken or tip-worn, adjustment may be difficult.
Also, using a metal-tip screwdriver makes capacitance adjustment difficult due to stray capacitance.  
Please use a ceramic-tipped screwdriver.

(2)The force applied by the screwdriver should be 1.0N or less to reduce drift after capacitance adjustment. 
If a force of 5.0N or more is applied, the product may be damaged or fail to function properly.
