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 Table). The dielectric is a
film of polypropylene (PP), polycarbonate (PC) or
polytetrafluorethylene (PTFE), which 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.
Versions are available with either a vertical spindle, or a
horizontal spindle.
Both versions have top adjustment by means of a
screwdriver or trimming key and bottom adjustment by
means of a key.
MINIMUM STORAGE TEMPERATURE:
- 55 °C
RELATED SPECIFICATION:
IEC 60418-1 and 4
EFFECTIVE ANGLE OF ROTATION:

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
subjected to the full test voltage.
