Vacuum Relay and Capacitor
Vacuum Relays are widely used in airborne, mobile and marine communications equipment. Typical applications include antenna coupling, tap changing on radio frequency (RF) coils, transmit / receive switching to an antenna, switching in pulse-forming networks and heavy duty power supplies. Our relays are noted for fast operating speeds and the ability to withstand high voltages and carry heavy currents, while maintaining low and stable contact resistance. Vacuum relays are available in SPST normally open (N/O) and normally closed (N/C) models, as well as SPDT configurations. Latching relays are available in some models.
Greegoo's high-voltage relay and vacuum capacitor are user-friendly and can fully replace those from Kilovac, Jennings, Crydom/Gigavac and Comet. If you cannot find a suitable model, please send us their part numbers, and we will recommend an appropriate one for you.

Fixed Vacuum Capacitor
High voltage tolerance, compact design, high quality factor (Q value), stable performance, high reliability, and cost-efficiency.
Semiconductor materials exhibit electrical properties that fall between those of good conductors and good insulators, with their ability to conduct electricity improving with increased temperature, light exposure, or applied voltage. Within the semiconductor manufacturing process, fixed vacuum capacitors and variable vacuum capacitor from the Greegoo brand play a pivotal role in the RF impedance matching networks of Chemical Vapor Deposition (CVD), Physical Vapor Deposition (PVD), and plasma etching (Etch) equipment. These vacuum capacitors are utilized to precisely adjust the transmission of RF power to dynamically match the impedance during plasma processes, ensuring process stability and repeatability. This is crucial for improving the uniformity and quality of thin-film deposition or etching.
