■ 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.
8. Do not use the trimmer capacitor under the
conditions listed below.
(1) Corrosive gasses atmosphere
(Ex. Chlorine gas, Hydrogen sulfide gas,
2. Before using trimmer capacitor, please store under
the condition of -10 to +40 C. and 30 to 85%RH.
3. Do not store in or near corrosive gasses.
4. Use within 6 months of deliverly.
Ammonia gas, Sulfuric acid gas, Nitric oxie gas,
etc.)
(2) In liquid (Ex. water, oil, medical liquid,
organic solvent, etc.)
5. Open the package just before using.
6. Prior to storing previously opened packages, the
packaging should be heat-sealed. Avoid using
rubber bands for repackage.
(3) Dusty / dirty atmosphere
(4) Direct sunlight
(5) Static voltage nor electric/magnetic fields
(6) Direct sea breeze
7. Do not store under direct sunlight.
(7) Other variations of the above
■ Notice (Soldering)
1. Soldering
capacitor characteristics, apply flux only to
terminals.
(1) TZ03 series can be soldered by flow soldering
method and soldering iron. Do not use reflow
soldering method.
2. Mounting
(1) Do not apply excessive force (preferable 5.0N
(Ref.; 500gf)max.), when the trimmer capacitor is
mounted on the PCB.
(2) Standard soldering condition
(a) Flow soldering : Refer to the standard
temperature profile.
(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.
(b) Soldering iron :
> Temperature of tip 260+-10 C.
> Soldering time
> Diameter
3 sec. max.
3mm max.
30W max.
> Wattage of iron
Before using other soldering conditions than those
listed above, please consult with Murata factory
representative prior to using. 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) 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 [with cover film type]
(3) The dimension of mounting hole should be used
Murata's standard mounting hole at flow
soldering. The amount of solder is critical.
Insufficient amounts of solder can lead to
insufficient soldering strength on PCB.
(1) Isopropyl alcohol and Ethyl alcohol are available
material for cleaning. Water group material like
Pinealpha, Cleanthru can not be used. For other
materials, please consult with Murata factory
representative prior to using.

Excessive amounts of solder may cause the
bridging between the terminals or the contact
failure due to flux wicking up.
(2) The total cleaning time by dipping, vapor and
ultra-sonic method shall be less than 2 minutes.
For ultra-sonic cleaning, the available condition
is as follows.
(4) When using soldering iron, 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 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 recommendable chlorine content of string
solder is 0.5wt% max.
> Cleaning time
> Power
: 30 sec. max.
: 20W/liter max.
: 20 - 60kHz
> Frequency
> Temperature
: Ambient temperature
Due to the ultra-sonic cleaning equipment
peculiar self resonance point and 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
conditions. If the trimmer capacitor is cleaned
by other conditions, the trimmer capacitor may
deviate from the specified characteristics.
(6) Do not use water-soluble flux (for water cleaning).
To prevent the deterioration of trimmer
