Aluminum electrolytic capacitors have better ripple current resistance and lower height

TDK Group has launched three new series of EPCOS aluminium electrolytic capacitors. Compared with the old series of the same size, B43743*/B43763* series screw capacitor has 40% higher ripple current resistance. The new series of capacitors operate in a voltage range of 350VDC to 450VDC, a capacitance range of 1,500µF to 18,000µF, a maximum allowable operating temperature of 105°C, and a service life of 6,000 hours at maximum operating temperature and rated current. The aluminum enclosures of the capacitors range in diameter from 64.3mm to 90mm and in height from 80.7mm to 221mm, depending on the model.

The corrugated current resistance performance of the welded chip capacitor has also been improved, such as the B43544* series capacitor of 400VDC and 450VDC, the corrugated current resistance performance has been improved by 20%. The new series of capacitors have an operating voltage range of 200VDC to 550VDC and a capacitance range of 47µF to 2700µF. The capacitor has a service life of 3,000 hours at 105°C maximum operating temperature and rated current. Aluminum enclosures for capacitors range from 22mm to 35mm and height from 25mm to 55mm, depending on the model.

B43641* series of solder capacitor is also a new series of products, using excellent compact design. Compared with the old series, the height of the new series of capacitors is 5mm lower, and the capacitance is the same. Capacitors are available in a height range of 25mm to 55mm, with aluminium housing diameters of 22mm to 35mm, and operating voltage ranges from 400VDC to 450VDC at 105C

It has a service life of 2,000 hours and a capacitance range of 120µF to 1200 µF.

The new EPCOS aluminium electrolytic capacitors are mainly used in industrial frequency converters and power supplies.
