FSC - DATASHEET
These capacitors are particularly suitable for telephone equipment where low loss, excellent stability and high reliability are required.

The 'high-rise' shape facilitates high packing density.

They consist of extended foil polystyrene capacitors sealed into a case with epoxy resin, both materials being resistant to cleaning fluids.

Considerable detailed data is available on specific components, for example :-

Loss factor at 120Hz, 1000Hz, 10KHz, 100KHz and 1MHz.

Self resonant frequencies.

The capacitance range can be extended up to 120,000pf with polypropylene dielectric ( see MKP/HP data sheet).
