Polystyrene Capacitors

Thu, 12/08/2005 - 6:11am

EXFS is a new range of precision polystyrene capacitors that are available from Saelig and manufactured by LCR Capacitors. EXFS capacitors are suited for audio and telephone equipment or any application where low loss, excellent stability and high reliability are required. Vertically-mounted for a high packing density, these capacitors are extended foil polystyrene capacitors sealed in a fluid- and temperature-resistant case. Values from 47 pF to 8200 pF are available with a tolerance of 1% and working voltage of 63 VDC. Insulation resistance is > 500 GΩ with a loss factor of 0.0003 and a tempco of 110 ppm/C (IEC40/070/56). Polystyrene is the dielectric of choice for capacitors with low leakage and low dielectric absorption. Even though raw polystyrene material is now no longer available, LCR Capacitors has acquired sufficient stock to manufacture at the present rate for a minimum of 15 more years.
