Compact Screw Terminal Series Aluminum Electrolytic Capacitors

EPCOS introduces their compact screw terminal series of aluminum electrolytic capacitors with high ripple current capability

Image of TDK Corporation/EPCOS, Inc.'s Compact Screw Terminal SeriesTDK Corporation presents three series of EPCOS aluminum electrolytic capacitors with screw terminals. They are characterized by their high ripple current capability and simultaneously highly compact dimensions.

The capacitors of the B43703 series are designed for rated voltages from 350 VDC to 450 VDC and cover a capacitance range from 1500 µF to 22,000 µF. They are up to 20 percent smaller than the capacitors of the preceding series at the same ripple current capability. The types have diameters of 51.6 mm to 90 mm and heights ranging from 80 mm to 197 mm.

The B43704 series offers not only a ripple current capability up to 25 percent higher than the capacitors in its preceding series, but also smaller dimensions. Their diameters are also between 51.6 mm and 90 mm with heights of between 80.7 mm and 221 mm. These capacitors are designed for rated voltages from 350 VDC to 550 VDC. Their capacitance extends from 820 µF to 22,000 µF.

In the B43705 series, the ripple current capability was increased by up to 40 percent compared with the capacitors in the prior series, while maintaining the same compact dimensions. These capacitors have diameters ranging from 51.6 mm to 90 mm and insertion heights from 80.7 mm to 221 mm. They are designed for rated voltages from 350 VDC to 450 VDC and their capacitance range extends from 1,000 µF to 18,000 µF.


  • Significantly higher ripple current capability and more compact dimensions compared with the prior series
  • Useful life of 12,000 hours at a maximum temperature of 85°C


  • Converters for use in industrial electronics
