■ 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.
•Corrosive gasses atmosphere
(Ex. Chlorine gas, Hydrogen sulfide gas, Ammonia
gas, Sulfuric acid gas, Nitric oxie gas, etc.)
•In liquid (Ex. water, oil, medical liquid, organic
solvent, 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.
•Dusty / dirty atmosphere
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.
•Direct sunlight
•Static voltage nor electric/magnetic fields
•Direct sea breeze
•Other variations of the above
7. Do not store under direct sunlight.
■ Notice (Soldering)
1. Soldering
(Ref.; 500gf)max.), when the trimmer capacitor is
mounted on the PCB.
(1)TZ03 series can be soldered by flow soldering
method and soldering iron. Do not use reflow
soldering method.
(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.
(2)Standard soldering condition
(a)Flow soldering : Refer to the standard
temperature profile.
(b)Soldering iron :
>Temperature of tip 260+-10 C.
(3)Do not apply bending stress more than 10.0N
(Ref.; 1kgf) after the trimmer capacitor has been
mounted on the PCB.
>Soldering time
>Diameter
3 sec. max.
3mm max.
30W max.
>Wattage of iron
(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]
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)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.
(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.
(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.
7
>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 such contact does occur, the trimmer capacitor
may be damaged.
If the trimmer capacitor is cleaned by other
conditions, the trimmer capacitor may deviate from
the specified characteristics.
(5)Our recommendable chlorine content of string solder
is 0.5wt% max.
(6)Do not use water-soluble flux (for water cleaning).
To prevent the deterioration of trimmer capacitor
characteristics, apply flux only to terminals.
2. Mounting
4. Other
Note the polarity of the trimmer capacitor to
minimize influence by stray capacitance.
(Refer to the dimensions concerning the polarity.)
(1)Do not apply excessive force (preferable 5.0N
