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.
When it comes to electrolytic caps, since they are hugely affected by increased temperatures caused by heat build-up at the PSU's internals (but mostly by current ripple), the caps made by Japanese manufacturers are the safest and highest-quality choice. This is also why Japanese capacitors are always preferred.
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.
This is also why Japanese capacitors are always preferred. However, there are two problems with using Japanese-made caps: their cost is higher and sometimes there are availability problems. Most PSU factories are located in China, so they have to import the capacitors from Japan, requiring additional time and shipping costs.
They also make high quality polymer SMT capacitors that are used as bulk capacitors on the power distribution circuitry on laptops and other devices. In the case of polymer caps, all types are considered good for PSU usage due to their ability to withstand higher operating temperatures than their electrolytic counterparts.
