Selecting the Best Capacitors for Power Supply Filtering
The trick in selecting a rectifier output capacitor, EMI filter capacitor, or power regulator output capacitor is to balance the required capacitance value with the other important specifications. The block diagram shows some spots where you will need to select different types of capacitors for your design.

Capacitor Basics and Their Uses in Power Applications
Capacitors play key roles in the design of filters, amplifiers, power supplies and many additional circuits. Here''s a brief guide to the different types and the …
transformerless
An ideal capacitor never converts any power to heat -- all of the electrical energy that flows into an ideal capacitor eventually flows out of the capacitor as electrical energy. A real capacitor has small amounts of parasitic series resistance (ESR) and parasitic parallel resistance, so a small amount of the input power is converted to heat.
