Aluminum electrolytic capacitors
Snap-in series with very high ripple current capability and longer useful life
TDK Corporation offers two new 105 °C snap-in series of EPCOS aluminum electrolytic capacitors with a very high ripple current capability and a longer useful life. The latter is 5000 h for the B43545* series. These capacitors are available with rated voltages of 400 V DC and 450 V DC as well as capacitances of 82 µF to 820 µF. The capacitors of the B43547* series have a useful life of 8000 h and a voltage range from 200 V DC to 450 V DC. They are available with capacitances of 82 µF to 2200 µF.
The thermal resistances and ESR values of both series were further reduced, so that the ripple current capability was significantly increased. Depending on the type, these new capacitors have dimensions of between 25 x 25 mm and 35 x 55 mm (d x h). They are designed for a maximum ambient temperature of 105 °C.
Their main applications are as DC link capacitors in frequency converters for drives and inverters for photovoltaic installations as well as industrial power supplies.
