Capacitors are passive devices that are used in almost all electrical circuits for rectification, coupling and tuning. Also known as condensers, a capacitor is simply two electrical conductors separated by an insulating layer called a dielectric. The conductors are usually thin layers of aluminum foil, while the dielectric can be made up of many materials including paper, mylar, polypropylene, ceramic, mica, and even air. Electrolytic capacitors have a dielectric of aluminum oxide which is formed through the application of voltage after the capacitor is assembled. Characteristics of different capacitors are determined by not only the material used for the conductors and dielectric, but also by the thickness and physical spacing of the components.
Capacitor - 500V, Silver Mica, ± 5%
± 5% tolerance radial lead capacitor, dipped in epoxy coating. 1000pF = 1nF = 0.001µF
Starting at $0.45
Capacitor - CDE, 500V, Silver Mica, Radial Lead, ±5%
High quality silver mica capacitors rated at 500V. These epoxy dipped capacitors made by Cornell Dubilier have a ±5% tolerance. The terminals are made of copper clad steel with a nickel undercoat and a 100% tin finish. Stability and mica go hand-in-hand when you need to count on stable capacitance over a wide temperature range. CDE’s standard dipped silvered mica capacitors are the first choice for timing and close tolerance applications.
Starting at $1.95
Capacitor - Vishay BC, Ceramic Disc, D Series, Radial Lead
High quality radial-leaded ceramic disc capacitors. These D Series capacitors are produced by Vishay BC, formerly known as Philips / BC. These capacitors have been produced for many years and can be found in a wide variety of vintage equipment. Suggested applications include general purpose use, temperature compensation, coupling, decoupling, and bypassing. Features
