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 60410”:
< 0.15 % major defects
< 0.65 % minor defects
Each capacitor is tested for minimum C_max and is also
subjected to the full test voltage.
C_min/C_max:
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)
