Aluminum electrolytic capacitors show various failure modes in different applications.

Capacitor Life

2021-04-22T13:56:34+00:00April 13, 2021|

The life of aluminum electrolytic capacitors is very dependent on environmental and electrical factors. Environmental factors include temperature, humidity, atmospheric pressure and vibration.

Capacitor Applications

2021-04-22T13:56:39+00:00April 6, 2021|

Aluminum electrolytic capacitors are used in virtually all types of circuit designs. However, they are commonly used as filtering devices in power supplies.

Guidelines for Using Aluminum Electrolytic Capacitors

2021-04-22T13:56:48+00:00March 29, 2021|

In DC applications, confirm the polarity. If the polarity is reversed, the circuit life will be shortened or the capacitor may be damaged. Generally, an intermittent reverse voltage of 1 volt DC is allowed. Capacitors used in circuits whose polarity is occasionally reversed or whose polarity is unknown requires the use of a bi-polar capacitor.
