TDK Epcos Shows Off Aluminum Electrolytic Capacitors at APEC

28 March 2017

The Applied Power Electronics Conference (APEC) is one the leading events for power electronics in the USA. One manufacturer of electronic and components systems, TDK EPCOS, develops products and solutions for automation, drives and traction. In particular, capacitors, inductors, protection devices, and wireless charging components and systems. The company is currently showing off its aluminum electrolytic capacitors.

Three new series of EPCOS aluminum electrolytic capacitors offer improved performance. The B43743*/B43763* series screw terminal capacitors features a 40 percent higher ripple current capability than the previous series of the same size. The new capacitors are designed for rated voltages between 350 V DC and 450 V DC and cover a capacitance range from 1500 µF to 18,000 µF. The components withstand a maximum operating temperature of 105 °C, at which a useful life of 6000 h is achieved, when operated at the rated current. Depending on the type, the can diameters range from 64.3 mm to 90 mm, and the heights from 80.7 mm to 221 mm.

The ripple current capability has also been increased for snap-in types, too. It is, for example, about 20 percent higher for the B43544* series that are designed for 400 V DC and 450 V DC. Altogether this series covers voltages from 200 V DC to 550 V DC and offers capacitances between 47 µF and 2700 µF. At the maximum operating temperature of 105 °C and the rated current, the useful life is 3000 hours. The can diameter ranges from 22 mm to 35 mm, and the heights from 25 mm to 55 mm.

The B43641* series of snap-in capacitors, which is also new, has an impressively compact design. The new capacitors feature an insertion height that is about 5 mm lower than that of the previous series while maintaining the same capacitance. The height ranges from 25 mm to 55 mm, and the can diameter from 22 mm to 35 mm. These capacitors are designed for voltages from 400 V DC to 450 V DC and for a useful life of 2000 hours at 105 °C. The capacitance range extends from 120 µF to 1200 µF.
