Company: LBA Group
The LBA Technology vacuum capacitors store maintains a large stock of all types of RF capacitors, both vacuum and mica capacitors. While LBA is a factory dealer specializing in COMET and JENNINGS fixed and variable vacuum capacitors, we can supply virtually any style, value, or manufacturer's product on special order. Typical of other brands supplied are Meiden, Sangamo, and Cornell Dubilier. We provide fast quotes and worldwide shipping.The high quality vacuum capacitors we stock and sell typically have capacitances from 3 pF to 6600 pF, and peak test voltages to 100 kV at 1000 amps. These include both fixed and variable styles. A full line of capacitor accessories such as cylometers, insulators, corona rings, and mounting hardware is available from LBA.Vacuum capacitors are used in a wide variety of applications that require the generation and management of high power radio frequency energy. The vacuum capacitor is extremely stable in electrical characteristics, has extremely low internal dissipation factor (loss) and withstands electrical overloads, such as lightning, with less damage than other types of capacitors. The vacuum capacitor is a key component in high frequency RF generators, industrial RF process applicators and antenna systems operating from low frequency through VHF, at power levels reaching and exceeding 1,000,000 watts. Both air-cooled and water-cooled vacuum capacitors, in fixed and variable styles are used.Vacuum capacitors are employed in broadcast transmitters for long wave, medium wave (MW or AM), short wave, and VHF (FM and TV). They also serve in broadcast antenna systems, particularly in AM directional antenna phasing systems, diplexers, triplexers and line tuning units.Vacuum capacitors find wide application in industrial applications of radio frequency energy. High power RF systems are found in RF dielectric heating devices such as RF welders, radio frequency sealers, RF process heating such as drying and baking ovens. The ubiquitous vacuum capacitor finds frequent application in such medical RF areas as MRI, CAT scanners, RF surgery, and high power particle accelerators. High power RF devices also use vacuum capacitors to help generate RF energy for laser systems, plasma generators, semiconductor foundries, research RF applications, and more.
