Film Dielectric Trimmers
FEATURES
•High temperature type
•Housing dimensions:
11mmx14mmx9mm
•For a basic grid of 2.54 mm
•Top adjustment
•Vertical version
APPLICATIONS
•For fine adjustment in professional applications
DESCRIPTION:
The trimmers consist of a glass reinforced polysulphone
frame with a polysulphone dust cover, brass rotor and stator
with PTFE or polycarbonate film as the dielectric. The stator
plates are stacked on pins and separated by rings, so that it
is possible to produce a single stator or a differential type.
The rotor contact surfaces are plated to ensure a long life
and a stable contact even under severe climatic conditions.
QUALITY LEVEL:
Sampling and data evaluation for quality level in accordance
with “MIL-STD-105D” and “IEC 60 410”:
< 0.15 % major defects
< 0.65 % minor defects
Each capacitor is tested for minimum Cmax and is also
subjected to the full test voltage.
Cmin/Cmax:
SINGLE STATOR TYPE
2.5/20 to 7/100 pF
DIFFERENTIAL TYPE
2/12 to 7/150 pF
RATED VOLTAGE (DC):
200 V
LIFE OF TRIMMER:
Maximum 10 cycles: rotation in 180° only (the electrical and
mechanical performance is not guaranteed if rotated beyond
10 cycles)
TEST VOLTAGE (DC) FOR 1 MINUTE:
400 V
MAXIMUM CONTACT RESISTANCE:
5 mΩ
MINIMUM INSULATION RESISTANCE BETWEEN
STATOR AND ROTOR:
10 000 MΩ
CATEGORY TEMPERATURE RANGE:
- 40 to + 125 °C
CLIMATIC CATEGORY (IEC 60068):
40/125/21
MINIMUM STORAGE TEMPERATURE:
- 55 °C
RELATED SPECIFICATION:
IEC 60418-1 and 4
EFFECTIVE ANGLE OF ROTATION:
180° (rotation in 180° only, see “Life of Trimmer”)
OPERATING TORQUE:
1.5 to 25 mNm
MAXIMUM AXIAL THRUST:
2 N

R = rotor, S = stator
Dimensions in millimeters
ADJUSTMENT:
The trimmers can be adjusted with a screwdriver or trimming
key. Capacitance increase is obtained with clockwise
rotation
MARKING:
The trimmers are marked with the capacitance value in pF,
followed by the letter ‘E’ (single-stator type) or the letter ‘D’
(differential type).
MOUNTING:
The trimmer can be mounted on printed-circuit boards with a
grid of 2.54 mm and a minimum hole diameter of 1.25 mm.
PACKAGING:
Blister packs of 70 units each. For smallest packaging
quantity (SPQ) see Electrical Data Table.
