Electrolytic Capacitors
Electrolytic capacitors have higher capacitance than
other capacitor types, and store large amounts of
energy in a small size. The large capacitance makes
them particularly suitable for DC power supply circuits,
where they attenuate ripple voltage, as well as for
coupling and decoupling applications. Electrolytic
capacitors are generally used in DC power supplies,
batteries and power filters.
The materials used to protect electrolytic capacitors
must be capable of withstanding stresses from voltage,
temperature and humidity, while at the same time
exhibiting excellent mechanical properties. A potting
compound is often added for additional protection.
By this way, a better stability and endurance is
guaranteed. Materials for the potting can be chosen
from very soft to rigid to meet the different demands.
