CONSTRUCTION DETAILS OF 4 x 4.5 mm GKG MODELS
Model GKG __ __ __ 27 Shown
• Special “drive assembly” with
pointed spring fingers to engage rotor
upper sur face contour. Spring fingers
also provide proper tension for smooth
torque and low resistance.
• Special rotor with die-formed “drive”
contour on upper sur face.
• Flat-lapped and lubricated sur faces
join for reliable capacitance settings.
• Special ceramic stator insert
with metalized electrode.
• Solid one-piece housing with integrally
molded terminals and contact areas.
Central tubular column is spun-out
into a flare after assembly to maintain
built-in spring tension.

SPECIFICATION NOTES
1. Parts are 100% tested for capacitance range,
dielectric withstanding voltage, insulation resis-
tance, and torque.
2. Capacitance range specified is that which is guar-
anteed, and is measured at 1 MHz and 25°C.
3. For soldering SURFTRIM®sur face mounting models,
pre-heat at 140°C ±10°C for 2 minutes maximum,
and reflow solder at 240°C ±5°C for 20 seconds
maximum.
4. For soldering printed circuit board mounting mod-
els, solder at 260°C ±10°C for 5 seconds maximum,
except 3 seconds maximum for Miniature Models
(page 10).
5. Q factor is measured at maximum rated capaci-
tance and at room temperature. Frequency of
measurement is as listed for each model.
6. Dielectric strength is measured at maximum rated
capacitance and room temperature, with test volt-
age as listed for each model applied for 5 seconds.
7. Insulation resistance is measured at maximum rated
capacitance and room temperature and at rated
voltage, unless otherwise specified.
8. Temperature coefficient of capacitance (TCC) is
measured at 100 kHz or 1 MHz, over a temperature
range of –20°C to +70°C with capacitor set at maxi-
mum rated capacitance.
9. Axial load during tuning should not exceed 250
grams.
10. Capacitors should not be operated outside of
rated capacitance range and working voltage.
11. Angular orientation of adjusting slot is random.
APPLICATION NOTES
Soldering and Cleaning
of Ceramic Trimmer Capacitors
Soldering temperatures and times are specified in
Notes 3 and 4 above. If using an iron for manual sol-
dering (for prototyping or repairs, for example) use
an appropriate size and temperature so that the
high temperature exposure of the trimmer is less
than 3 seconds.
We strongly recommend the use of water soluble
fluxes for soldering, followed by cleaning in water
containing detergents, and then a clear water
rinse.
Some operations still use Freon or similar fluorinated
or chlorinated hydrocarbon solvents. These solvents
have a tendency to remove the lubricant, which in
turn makes for bumpy adjustment, and will degrade
the tuning torque, adjustment life, and other
mechanical specifications.
In general, the minimum exposure to cleaning solu-
tions is recommended. The gentlest would be the
detergent and water rinses at fairly low tempera-
tures. When chlorinated or fluorinated hydrocarbons
are used, the boards should never be plunged into
the solvent solution, but rather maintained in the
vapor area of the defluxing equipment, and for the
minimum possible time. Most desirable would be to
clean only the bottom of the printed circuit board,
as with board scrubbers.
The unsealed GKG models are usually specified for
consumer applications where cleaning after soldering
is nor mally not required. Should cleaning be required,
the method to use would be to clean the bottom of
the board, as with board scrubbers. If a solvent is used
when cleaning the GKG series, sealed versions should
be specified to prevent the solvent from being
trapped in the housing and degrading per for mance.
Other precautions for using ceramic trimmer capaci-
tors include:
• Beware of excessive handling with bare hands
as, “finger oil” and dirt can bring down Q and
insulation resistance values.
• Ter minals should not be cut or reformed, as this
could cause defor mation of the spring or break-
ing of the rotor.
