Finding a Replacement Electrolytic Capacitor | DigiKey
While there are many types, shapes, sizes, and specifications, this article will focus on aluminum electrolytic capacitors and how to properly cross them. The first step to finding a cross is identifying the bad capacitor, and correctly reading the specifications printed on the top or side of the capacitor.
