How to select capacitance quickly in switching power supply (I)

1.Understanding of capacitance types.

Approximate understanding of capacitance types helps to quickly filter capacitor types when selecting capacitance.

There are many kinds of capacitors according to the structure situation according to the structure situation which includes ceramic capacitor tantalum capacitor electrolytic capacitor mica capacitor film capacitance according to dielectric capacitor and capacitor.

There are fixed capacitance semi-fixed capacitance variable capacitance.

There are many kinds of capacitors which make people fall into difficulty problems easily but without worry we use ceramic capacitors electrolytic capacitors and tantalum capacitors most commonly used in switching power supply.

So what we're going to learn today is the capacitance performance parameters.

2. Understanding of key parameters of capacitance.

Understanding the intrinsic key parameters of capacitance can quickly select reliable use all capacitance key parameters are identical.

Including capacitance voltage value capacitance ESR capacitance accuracy capacitance allowable working temperature range.
