Compact single-ended aluminium electrolytic capacitors with high current capability

New Products |
By Nick Flaherty

The EPCOS B41897 series are available for rated voltages of between 25 V DC and 75 V DC and cover a capacitance range from 270 µF to 12,000 µF. The dimensions of the new components range from 12.5 mm x 20 mm to 18 mm x 40 mm (d x l) depending on the voltage and capacitance.

The capacitors use new materials for high temperature operation and are designed for continuous operation at up to 135 °C and for a peak temperature of 150 °C. In comparison with previous series, it has been possible to increase the ripple current capability while at the same time raising the capacitance by as much as 60 percent. This means that the maximum ripple current capability is now higher than 7 A at 125 °C and 100 kHz.

Luanched at Electronica in Munich this week, typical applications include automotive ECUs and power supplies.
