CATEGORY TEMPERATURE RANGE:
PP
- 40 to + 70 °C
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.
