Aluminum Capacitors Handle High Ripple Currents

 

TDK Corporation announces three additional series of EPCOS aluminum electrolytic capacitors with screw terminals for converters in industrial electronics.  They are distinguished by their high ripple current capability and highly compact dimensions.

Capacitors of the new B43703 series are designed for rated voltages from 350 VDC to 450 VDC and cover a capacitance range from 1,500 µF to 22,000 µF.  They are up to 20 percent smaller than those of the previous series at the same ripple current capability.  The new types have diameters of 51.6 mm to 90.0 mm and heights ranging from 80.7 mm to 197.0 mm.

The new B43704 series offers not only ripple current capability up to 25 percent higher than predecessors but also smaller dimensions.  Their diameters are also between 51.6 mm and 90.0 mm with heights between 80.7 mm and 221.0 mm.  These capacitors are designed for rated voltages from 350 V DC to 550 V DC.  Their capacitance extends from 820 µF to 22,000 µF.

In the new B43705 series, the ripple current capability was increased by up to 40 percent compared with predecessors while maintaining the same compact dimensions.  Their diameters range from 51.6 mm to 90.0 mm and insertions heights from 80.7 mm to 221.0 mm.  They are designed for rated voltages from 350 V DC to 450 V DC, and their capacitance range extends from 1,000 µF to 18,000 µF.

All three new EPCOS series are designed for a maximum operating temperature of 85 oC and attain a useful life of 12,000 hours.  The series are also offered in B43723, B43724, and B437258 versions.  These types additionally have a threaded stud on the base of the can for mounting.
