CAPACITORS


Capacitors are playing a key role in almost all electrical and electronic equipment and electrotechnical installations. These versatile components store electric charges and smooth or buffer currents and voltages. They are used to filter and suppress HF interference as well as to decouple signals in telecommunications applications. Capacitors can in principle be subdivided into two groups depending on their construction: those in dry technology and those based on wet technologies with electrolytes. The former include film and ceramic capacitors, while the latter comprise aluminum electrolytic and tantalum capacitors.

Depending on the technology and applications, capacitors are manufactured for voltages from a few to over 10 000 volts. Their capacitance values extend from picofarads to the lower farad range.
