The TDK Group introduces three new series of EPCOS aluminum electrolytic capacitors . The B43743*/B43763* series of screw capacitors have a 40% higher ripple current resistance than the older series of the same size. The new series capacitors operate from 350VDC to 450VDC, have a capacitance range of 1,500nF to 18,000nF, have a maximum allowable operating temperature of 105°C, and have a lifetime of 6,000 hours when operated at maximum operating temperature and current rating. Capacitor aluminum housing diameters range from 64.3mm to 90mm and heights range from 80.7mm to 221mm, depending on the model.

The ripple current resistance of the chip capacitors has also been improved. For example, the B43544* series capacitors operating at 400 VDC and 450 VDC have improved ripple current performance by 20%. The new series of capacitors operate from 200VDC to 550VDC and have capacitances from 47μF to 2700μF. Capacitor life is up to 3,000 hours when operating at 105 ° C maximum operating temperature and rated current. Capacitors have an aluminum housing range of 22mm to 35mm and a height of 25mm to 55mm, depending on the model.

The B43641* series of chip capacitors are also a new range of products with an excellent compact design. Compared with the old series, this new series of capacitors has a height of 5mm and a comparable capacity. The capacitors range in height from 25mm to 55mm, aluminum housing diameters from 22mm to 35mm, operating voltages ranging from 400VDC to 450VDC, lifetimes up to 2,000 hours at 105C, and capacitances ranging from 120μF to 1200μF.

The new EPCOS aluminum electrolytic capacitors are mainly used in industrial inverters and power supplies.
