DESCRIPTION:
The vanes of the trimmer are stacked on a sturdy plastic
base. The color of the base indicates the maximum
capacitance (see Electrical Data Tables). The dielectric is a
film of polypropylene (PP) or polytetrafluorethylene (PTFE)
for the standard versions and polycarbonate (PC) for the
economic and hexagonal head versions. The dielectric
supports the vanes in such a way that good stability is
ensured and no microphony can occur.
Flux absorption between the vanes is prevented.
Cleaning with solvents is not advised.
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:
0.35/1.5 to 4/27 pF
RATED VOLTAGE (DC):
150 V
TEST VOLTAGE (DC) FOR 1 MINUTE:
300 V
LIFE OF TRIMMER:
Maximum 10 cycles: Rotation in 180° only (the electrical and
mechanical performance is not guaranteed if rotated beyond
10 cycles)
