■Introduction
HEV capacitor is not a power source for a vehicle, but a full hybrid power system of the 272-650V high voltage starting motor, which can be adapted to the full hybrid electric system of the high voltage starting motor. This product is dry film capacitor, the use of high temperature resistant plastic shell, can be based on the car engine compartment space and capacitance extraction requirements, can be used in complex form. This product uses the ultra thin high temperature metal film, the metal electrode thickness with the current distribution change, and the electrode on the electrode design, the energy density is big, the volume is small, has the safety explosion-proof function, the capacitor the highest operating temperature can reach 105. ESR and ESL are low, can withstand high ripple current. According to the user's need to be built in the internal Y capacitor and discharge resistance, increase the reliability and safety of the capacitor.
