To start selecting the best capacitors for power supply filtering, you need to get into a capacitor datasheet and delve through some specifications. Some of the important specifications are as follows: Capacitor material: Your capacitor might be a ceramic, electrolytic, tantalum, polyester, or other material.
The filter capacitor should be chosen with low ESR value while also providing high capacitance; ceramics are a good choice here as they tend to have very low ESR. When designing an EMI filter, the important point is the topology of the circuit and the exact capacitance value.
With the right capacitor (or capacitor bank), you’ll be able to dampen voltage ripple from your rectifier while ensuring a long lifetime. Although most subjects involving “filter capacitors” simply refer to the output capacitor on a rectifier, it can also refer to the capacitor on the output of a voltage regulator.
in capacitor and filtering technologies. Some of these developments include:− The intro uction of low voltage dry capacitor technology using metallized plastic film. This technique had the advantage over rival technologies at the time by providing capacitors that wer
Polarization: Filter capacitors for DC circuits have some specified polarization, which states the direction the electric field should point across the capacitor. Excessively large AC voltage across a polarized capacitor can destroy the component prematurely.
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.
