!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 delivery.
5. Do not store under direct sunlight.
6. 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) TZC3 series can be soldered by reflow soldering
method and soldering iron. Do not use flow
soldering method (dipping).
(2) Soldering condition
Refer to the temperature profile.
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 amount of solder is critical.
(4) The thickness of solder paste should be printed
from 150 micro m to 200 micro m and the dimension
of land pattern should be Murata's standard land
pattern used at reflow soldering.
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.
(5) When using soldering iron, the diameter of the
string solder shall be less than 0.5mm. 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 metal rotor or
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 stator
of the trimmer capacitor. If such contact does occur, the
trimmer capacitor may be damaged.
(6) Our recommended chlorine content of solder is as follows.
(a) Solder paste: 0.2wt% max.
(b) String solder: 0.5wt% max.
(7) Do not use water-soluble flux (for water cleaning).
To prevent the deterioration of trimmer capacitor
characteristics, apply flux only to terminals.
(8) When soldering the TZC3 series, the solder
should not flow into the staking part of the
substrate. If such flow does occur, driver slot
rotation will be damaged.
2. Mounting
(1) Do not apply excessive force (preferably 5.0 N
[Ref: 500gf] max.), when the trimmer capacitor
is mounted on the PCB.
(2) Do not warp and/or bend PCB to prevent trimmer
capacitor from breakage.
(3) Use the suitable dimension of the pick-up nozzle
(2.5mm external diameter and 1.5mm bore diameter).
3. Cleaning
Cannot be cleaned because of open construction.
4. Other
Note the polarity of the trimmer capacitor to
minimize influence by stray capacitance.
(Refer to the dimensions concerning the polarity.)
■ Notice (Handling)
1. Use suitable screwdrivers that fit comfortably in
driver slot.
(1) Recommended screwdriver for manual adjustment
Standard type --> MURATA: KMDR010
Cross slot type --> TORAY: SA-1825
(Murata P/N is KMDR040)
(2) Recommended screwdriver bit for automatic
adjustment
Standard type --> MURATA: KMBT010
Cross slot type --> TORAY: JB-1825
(Murata P/N is KMBT040)
2. When adjusting with a screwdriver, do not apply
excessive force (preferably 1.0 N [Ref: 100gf] max.)
to minimize capacitance drift. If excessive force
is applied to the screwdriver slot, it may cause
deformation of the products.
3. Do not apply adhesive, lock paints, or any other
substances to the trimmer capacitor to secure the
rotor position. They may cause corrosion or
electrical contact problems.
■ Notice (Other)
Before using trimmer capacitor, please test after
assembly in your particular mass production system.
