TDK Corporation has introduced a very compact EPCOS film capacitor for the DC link of inverters. It measures only 40mm x 58mm (dxl), offers a rated voltage of 350VDC and a capacitance of 65μF. This means that the capacitor has a very high capacitance density of 0.9 μF / cm3, and the capacitance per volume is 50% higher than similar capacitors. It requires relatively little space on the PCB. Other key points include low ESR of only 10mOhm and high ripple current capability of 3.7A.
Both plastic cans and epoxy sealing materials have been developed as flame retardant materials in accordance with UL 94 V0. This capacitor is designed for a temperature range of -25C to + 65C. The capacitor has a built-in thermal fuse that trips at 5A and 115C.
Typical applications include HF filtering in inverters (for example, home appliances) and general DC applications.
