TDK Corporation, a provider of passive components and magnetic application products has introduced two new 105 degree Celsius snap-in series of EPCOS aluminum electrolytic capacitors with a very high ripple current capability and a longer useful life. The latter is 5,000h for the B43545 series.
These capacitors are available with rated voltages of 400V DC and 450V DC as well as capacitances of 82mcF to 820mcF. The capacitors of the B43547 series have a useful life of 8,000h and a voltage range from 200V DC to 450V DC. They are available with capacitances of 82mcF to 2,200mcF.
The company said that 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. They are designed for a maximum ambient temperature of 105 degree Celsius.
Their main applications are as DC link capacitors in frequency converters for drives and inverters for photovoltaic installations as well as industrial power supplies.
