Replacing Capacitors in Old Radios and TVs
Types of Capacitors. Before getting to work, let''s make sure you know what to replace. Some kinds of capacitors—paper, molded paper, and electrolytics—are failure-prone and need to be replaced. Other kinds, such as mica and ceramic, rarely need replacement. To avoid wasting time and money, you must be able to tell them apart.

Ripple current of MLCC (2): Why do MLCCs (Multilayer Ceramic …
An ideal capacitor does not self-heat with the charge and discharge current (ripple current) that enters and leaves. However, actual multi-layer ceramic capacitors (MLCCs) have very low equivalent series resistance (ESR) and therefore will experience a small loss. This loss generates a small amount of heat, sometimes called Joule heating.
