!Note • Please read rating and !CAUTION (for storage, operating, rating, soldering, mounting and handling) in this catalog to prevent smoking and/or burning, etc.
• This catalog has only typical specifications because there is no space for detailed specifications. Therefore, please approve our product specifications or transact the approval sheet for product specifications before ordering.
■ 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.
2. Before using trimmer capacitor, please store under
the condition of -10 to +40 degree C and 30 to
85%RH.
3. Do not store in or near corrosive gasses.
4. Use within 6 months of deliverly.
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 repackaging.
7. Do not store under direct sunlight.
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 oxide gas,
etc.)
(2) In liquid (ex. water, oil, medical liquid,
organic solvent, etc.)
(3) Dusty / dirty atmosphere
(4) Direct sunlight
(5) Static voltage nor electric/magnetic fields
(6) Direct sea breeze
(7) Other variations of the above
■ Notice (Soldering and mounting)
1. Soldering
(1) TZ03 series can be soldered by flow soldering
method and soldering iron. Do not use reflow
soldering method.
(2) Standard soldering condition
(a) Flow soldering: Refer to the standard
temperature profile.
(b) Soldering iron:
> Temperature of tip 260+-10 degree C
> Soldering time 3 sec. max.
> Diameter 3mm max.
> Wattage of iron 30W max.
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 Murata's
standard mounting hole used 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 bridging between the terminals
or 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. Do not apply flux except to 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.
(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
(1) Do not apply excessive force (preferable 5.0N
(Ref.; 500gf) max.), when the trimmer capacitor
is mounted on the PCB.
(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.
(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
(1) Isopropyl alcohol and Ethyl alcohol are available
material for cleaning. Water group materials like
Pinealpha, Cleanthru cannot 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.
> Cleaning time: 30 sec. max.
> Power: 20W/liter max.
> Frequency: 20 - 60kHz
> Temperature: Ambient temperature
Due to the ultra-sonic cleaning equipment's
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
