Difference between electrolytic and non-electrolytic capacitors?

Electrolytic Capacitors:

1. It provides high capacitance in small volume.

2. It has got polarity.

3. It is not suitable for high frequencies due to losses in dielectrics.

4. It is generally available in 1-100 µF range

Non-Electrolytic Capacitors:

1. Its capacitance depends on dielctric constant of the bulk.

2. It doesn't have polarity.

3. It is widely used at all frequencies.

4. It ranges from pico Farads to fractions of µF.
