■ 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.
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 oxie gas,
etc.)
2. Before using trimmer capacitor, please store under
the condition of -10 to +40 degrees C and 30
to 85%RH.
(2) In liquid (Ex. water, oil, medical liquid,
organic solvent, etc.)
3. Do not store in or near corrosive gasses.
4. Use within 6 months of delivery.
(3) Dusty/dirty atmosphere
5. Do not store under direct sunlight.
(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
of the terminal may cause fixed metal 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 monolithic stator of the trimmer capacitor.
If such contact does occur, the trimmer
capacitor may be damaged.
(1) TZW4 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.
(6) Our recommended chlorine content of solder is
as follows.
(a) Solder paste: 0.2wt% max.
(3) The amount of solder is critical.
(b) String solder: 0.5wt% max.
(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.
(7) Do not use water-soluble flux (for water
cleaning). To prevent the deterioration of
trimmer capacitor characteristics, apply flux
only to terminals.
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.
2. Mounting
(1) Do not apply excessive force (preferably 5.0 N
[Ref: 500gf] max.), when the trimmer capacitor
is mounted on the PCB.
6
(2) Do not warp and/or bend PCB to prevent trimmer
capacitor from breaking.
(5) When using soldering iron, the diameter of the
string solder should be less than 0.5mm. The
string solder should 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
(3) Use the suitable dimension of the pick-up nozzle
(1.8mm external diameter and 1.1mm bore
diameter).
3. Cleaning
Cannot be cleaned because of open construction.
■ Notice (Handling)
1. Use suitable screwdrivers that fit comfortably in
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.
driver slot.
-Recommended screwdriver for manual adjustment
VESSEL: No.9000 -1.3x30
(Murata: KMDR130)
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
applied to the screwdriver slot, it may cause
deformation of the products.
■ Notice (Other)
Before using trimmer capacitor, please test after
assembly in your particular mass production system.
