■ N o t i c e ( S torage and operat i n g cond i t i o n)
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,
Ammonia gas, Sulfuric acid gas, Nitric oxie gas,
etc.)
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.
(2) In liquid (Ex. water, oil, medical liquid,
organic solvent, etc.)
5. Open the package just before using.
(3) Dusty / dirty atmosphere
6. Prior to storing previously opened packages, the
packaging should be heat-sealed. Avoid using
rubber bands for repackage.
(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
■ N o t i c e ( S o l d e r ing)
1. Soldering
cleaning).
(1) TZ03 series can be soldered by flow soldering
method and soldering iron. Do not use reflow
soldering method.
To prevent the deterioration of trimmer
capacitor characteristics, apply flux only to
terminals.
(2) Standard soldering condition
(a) Flow soldering : Refer to the standard
temperature profile.
2. Mounting
(1) Do not apply excessive force (preferable 5.0N
(Ref.; 500gf)max.), when the trimmer capacitor
is mounted on the PCB.
(b) Soldering iron :
> Temperature of tip 260+-10 C.
(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.
> 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.
Excessive amounts of solder may cause the
bridging between the terminals or the contact
failure due to flux wicking up.

(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.
(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.

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
(5) Our recommendable chlorine content of string
solder is 0.5wt% max.
(6) Do not use water-soluble flux (for water
