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 applications they ...

The diagram above shows two op-amp circuits, both using a non-polarized capacitor that will affect the circuit if it receives external interference.

What he came up with is a non-polarized capacitor in series followed by a pair of PIN diodes shunted to ground. The diodes are in opposite polarities and serve to limit how much voltage passes out ...

As polarized aluminum electrolytic capacitors with a non-solid electrolyte, the RoHS-compliant devices are ideally suited for smoothing, filtering, and buffering in switch mode power supplies and ...
