The oldest capacitor companies were founded over 100 years ago. Most older companies were founded during the AM radio era, which includes the World War II era and post war era. As the demand for advanced electronics continues to grow, the role of capacitor manufacturers becomes increasingly vital, supporting crucial domains like consumer ...
Capacitors for AC applications are primarily film capacitors, metallized paper capacitors, ceramic capacitors and bipolar electrolytic capacitors. The rated AC load for an AC capacitor is the maximum sinusoidal effective AC current (rms) which may be applied continuously to a capacitor within the specified temperature range.
Schematic illustration of a supercapacitor [1] A diagram that shows a hierarchical classification of supercapacitors and capacitors of related types. A supercapacitor (SC), also called an ultracapacitor, is a high-capacity capacitor, with a capacitance value much higher than solid-state capacitors but with lower voltage limits.
Capacitors used for suppressing undesirable frequencies are sometimes called filter capacitors. They are common in electrical and electronic equipment, and cover a number of applications, such as: Glitch removal on direct current (DC) power rails; Radio frequency interference (RFI) removal for signal or power lines entering or leaving equipment
The tests and requirements to be met by capacitors for use in electronic equipment for approval as standardized types are set out in the following sectional specifications IEC 60384-4, Fixed capacitors for use in electronic equipment - Part 4: Sectional specification - Aluminium electrolytic capacitors with solid (MnO 2) and non-solid electrolyte

Nichicon Corporation (ニチコン株式会社, Nichikon Kabushiki-gaisha) is a manufacturer of capacitors of various types, and is one of the largest manufacturers of capacitors in the world, [citation needed] headquartered in Karasuma Oike, Nakagyō-ku, Kyoto, Japan. In 1950, it separated from the Nii Works Co., established itself as Kansai ...
Aluminium electrolytic capacitors form the bulk of the electrolytic capacitors used in electronics because of the large diversity of sizes and the inexpensive production. Tantalum electrolytic capacitors, usually used in the SMD (surface-mount device) version, have a higher specific capacitance than the aluminium electrolytic capacitors and are ...
