1.CBB15 CBB16 Welding Inverter DC Filter Capacitor This type of capacitor can be used as intermediate circuit for dc connection and harmonic filter.Meanwhile, it can also be used as the embedded and absorbing capacitor in the control circuit. Through special vacuum evaporation process, the coating film has different thickness in different positions. The special structure of the metallized coating makes the healing property and series resistance more reasonable, and the actual structure makes the performance of the capacitor more thoroughly. The equivalent series resistance of it is low.Besides, it is able to withstand high ripple current and high current impulse. 2.Applications (1)Used in filter,absorption,blocking,resonance circuits of high-frequency switching power supply. (2)Widely applied to EMI,such as high frequency welding inverter,UPS,electric vehicles,etc.
