A capacitor is a passive two terminal electronic component that stores electrical energy in an electric field.The effect of a capacitor is known as capacitance.While some capacitance exists between any two electrical conductors in proximity in a circuit, a capacitor is a component designed to add capacitance to a circuit.The capacitor was originally known as a condenser or condensator.Different Types of Capacitors And Their Applications
Capacitors are used commonly and useful as an electronic component in the modern circuits and devices.The capacitor has a long history and usage with more than 250 years ago the capacitors are the oldest electronic component being studied, designed, developed and used.RF Tunable Capacitors STMicroelectronics
ST’s STPTIC devices form a series of tunable RF capacitors intended for use in mobile phone applications, dedicated to RF tunable applications, which features standard capacitor values ranging from 1.5 pF to 8.2 pF. Available in flip chip and micro QFN packages, ST’s tunable capacitors are controlled through a bias voltage ranging from 1 to 24 V, with a tuning ratio of 5 to 1.Capacitor ESR Meter Electronics DIY Quality Electronic ...
A typical capacitor checker measures the capacity (usually in micro farads) of the test capacitor. Some advanced units also test for leakage current. Most of these testers require that the capacitor be removed from the circuit. Unless the capacitor has totally failed, they will not detect a high ESR value. In a typical circuit, there may be 10's or 100's of capacitors.13.8V 10A Power Supply Quality Electronic Kits ...
As is commonly the case, this supply was born of necessity. There is absolutely nothing special about the circuit, except that as shown, it is quite capable of up to 20 Amps intermittently or 10A continuous. Simply use a bigger transformer, bridge rectifier and more capacitors and output transistors to get more current. The basic circuit should be good for up to 100A or so, using a 5A TO3 ...Electronic Circuits and Diagrams Electronic Projects and ...

A supercapacitor (SC) (also called a supercap, ultracapacitor or Goldcap) is a high capacity capacitor with capacitance values much higher than other capacitors (but lower voltage limits) that bridge the gap between electrolytic capacitors and rechargeable batteries.They typically store 10 to 100 times more energy per unit volume or mass than electrolytic capacitors, can accept and deliver ...HobbyTronics | ponents
