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 ...
Crossovers are used in loudspeaker cabinets, power amplifiers in consumer electronics (hi-fi, home cinema sound and car audio) and pro audio and musical instrument amplifier products. For the latter two markets, crossovers are used in bass amplifiers , keyboard amplifiers , bass and keyboard speaker enclosures and sound reinforcement system ...
Variable capacitors are often used in L/C circuits to set the resonance frequency, e.g. to tune a radio (therefore it is sometimes called a tuning capacitor or tuning condenser), or as a variable reactance, e.g. for impedance matching in antenna tuners.
The radio frequency current from the transmitter is supplied to the antenna through a cable called the feedline.The antenna tuning hut contains a matching network made of high wattage capacitors and inductors (coils) that in combination match the antenna's impedance to the feedline, to efficiently transfer power into the antenna.
Vacuum variable capacitors are commonly used in high-voltage applications: 5000 volts (5 kV) and above.They are used in equipment such as high-powered broadcast transmitters, amateur radio RF amplifiers and large antenna tuners.
Power capacitors, motor capacitors, DC-link capacitors, suppression capacitors, audio crossover capacitors, lighting ballast capacitors, snubber capacitors, coupling, decoupling or bypassing capacitors. Often, more than one capacitor family is employed for these applications, e.g. interference suppression can use ceramic capacitors or film ...
