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.
40/070/21
Cleaning with solvents is not advised.
