(All manuals in PDF format unless noted otherwise)

The General Radio 505 Capacitor was introduced in Bulletin 936 (1935) and remained available through Catalog S (1965).

The Type 505 is a secondrary standard capacitor using a silvered-mica dielectric. The capacitor is installed in a low-loss phenolic case along with Silica gel desiccant then sealed with wax. The Type 505 has almost as equally high stability as the 1409 Standard Capacitor at one quarter the cost. The Type 505 is found in many General Radio instruments as a capacitance standard. It is supplied in two case sizes, the small and large.


The 505 series of standard capacitors comprises

Specifications

  • Accuracy: at 1 kHz, ±0.5% or ±3 pf, whichever is the larger
  • Dielectric: Silvered-Mica
  • Temperature Coefficient: Approximately +35 ppm per degree Centigrade between 10 and 50 C. Calibration is made at 23 C, at a frequency of 1 kHz
