Replacing Capacitors in Old Radios and TVs
Electrolytic capacitors are polarized, meaning that they have positive (+) and negative (-) leads. Electrolytics are the largest capacitors in the radio, with values from about 5 mfd (microfarads) to as much as 80 or even 200 mfd. Common values are 20 mfd and 40 mfd. Electrolytic capacitors are very failure-prone and are usually replaced.

Electrolytic capacitor
OverviewGeneral informationTypes and features of electrolytic capacitorsHistoryElectrical characteristicsOperational characteristicsCauses of explosionAdditional information
An electrolytic capacitor is a polarized capacitor whose anode or positive plate is made of a metal that forms an insulating oxide layer through anodization. This oxide layer acts as the dielectric of the capacitor. A solid, liquid, or gel electrolyte covers the surface of this oxide layer, serving as the cathode or negative plate of the capacitor. Because of their very thin dielectric oxide layer and enlarged an…
