Capacitor Types | Capacitor Guide
Electrolytic Capacitor This is the type of capacitor that uses an electrolyte to achieve a larger capacitance than other types of capacitor. An electrolyte is a liquid/gel that contains a high concentration of ions. Almost all electrolytic capacitor are polarized making the voltage at the positive terminal always greater than the negative terminal.

Sequential power-up can be easily implemented in iP1201/2 designs by tuning the soft start capacitors. Use the following formula for setting the value of the soft start capacitors: . …
The ESR (Equivalent Series Resistance) of Capacitors
If you want to improve a power supply with mediocre capacitors, by replacing its capacitors with high quality capacitors, you will have improved it significantly. When repairing switch-mode power supplies, you must also be careful in selecting the capacitors you will use, and strike the right balance between price and availability and the result of …
