The General Radio 1419-B Decade Capacitor was introduced in Catalog Q (1961) and remained available through Catalog 1978.

The Type 1419-B is a four decade capacitance standard based on the Type 980 series of polystyrene decade capacitors. Its comprised of the Types 980-A, 980-B, 980-C, and 980-D decade units. Polystyrene types offer lower dissipation factor and dielectric absorption than silver mica types. The entire assembly enclosed in a shielded enclosure. Binding post connections are provided for two or three terminal connections using a shorting link. Applications for the 1419-B include, elements in resonant circuits, bridge measurements, filters, and experiment laboratory use.


  • Total Capacitance: 1.1110 μF
  • Capacitance Per Step: .0001 μF
  • Accuracy: two terminal ±1% ; three terminal ±1%, ±1.5% at the third decade, ±1% to (-2% + 4 pF) smallest decade
  • Dissipation Factor: less than 0.0002 at 1 kHz
  • Maximum Voltage: 500 V
