A Complete Guide to Capacitors
The three-digit code printed on their body is used to identify the capacitor''s value in the picofarad. Letter codes are used to indicate their tolerance value such as the following: J = 5%, K = 10% or M = 20%. For example, the ceramic disc capacitor above with a ...
Capacitors Basics
What are capacitors? In the realm of electrical engineering, a capacitor is a two-terminal electrical device that stores electrical energy by collecting electric charges on two closely spaced surfaces, which are insulated from each other. The area between the conductors can be filled with either a vacuum or an insulating material called a dielectric. …
