1419-K

The General Radio 1419-K Decade Capacitor was introduced in Catalog P (1959) and remained available through Catalog 1978.

The Type 1419-K is a three decade capacitance standard based on the Type 505 capacitor. Its comprised of the Types 980-F, 980-G, and 980-H decade units which in turn are comprised of four Type 505 silver mica capacitors. The mica dielectric permits operation at higher temperatures than possible with polystyrene 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-K include, elements in resonant circuits, bridge measurements, filters, and experimental laboratory use.
