HEC's HT50 HT57 series and Vishay TOS 030033 and TOS 020016 Series are major RF power barrel producers in the world. HVC Capacitor's HVC HF series can be good alternative and replacement equivalent for HEC HT50 and HEC HT57 RF capacitors. This is major type of RF Power Ceramic doorknob capacitor. Application is anticore antenna emission, high frequency dielectric heating, radio frequency power supply, medical equipment, radar, etc.
Covid19 Pandemic leads to European and American supply chain problem, many industrial products include High Energy Capacitor (HEC) and Vishsy-Draloric stop production and cause big shortage. Existing RF Capacitor user eagerly seeking for the HVC 's HVCHF series high voltage RF capacitor as alternative , HVCHF series HV HF Capacitor already approval by lots RF power supply ,radar equipment manufacturer - HEC HT50 and HEC HT57.
Such high-frequency ceramic capacitors can be traced back to 70 years ago, and USSR supports China's construction of high level capacitor production line. HEC HT50 and HEC HT57, After decades of production improvement, China's ceramic dielectric powder suppliers developed world class dielectric material like NPO, N750, N4700 , Y5T, X5U, etc. HVC Capacitor using these type of Class I and Class II dielectric build our brand of RF power barrel capacitor product .The main features are low loss, high reliability, and high rated voltages. HVC RF ceramic capacitor major application market are RF power supply, induction heating, medical equipment ,gem smelting, and radar communication.
