Standard Capacitor Values & Color Codes

Over time, a series of standard capacitor values have evolved, just as with resistors and inductors. Capacitors are available in a huge range of package styles, voltage and current handling capacities, dielectric types, quality factors, and many other parameters. Still, they largely hold to this range of values.

Capacitors are one of the four fundamental types of passive electronic components; the other three are the inductor, the resistor, and the memristor. The basic unit of capacitance is the Farad (F).

In order to obtain other values of capacitance, it is necessary to use parallel and/or series combinations. Often, complex combinations are used in order to satisfy multiple requirements such as handling large voltages while still providing the correct amount of capacitance.

If it is necessary to provide occasional tuning of a circuit, then it is necessary to use a variable capacitor. That can take the form of a manually adjusted capacitor, or an electrically tuned capacitor like a varactor diode (varicap).

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
