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

and is also
subjected to the full test voltage.
