TDK Corporation launches axial hybrid-polymer aluminium electrolytic capacitors

TDK Corporation, a leader in electronic solutions for the smart society based in Tokyo, Japan, has extended its product range with the launch of axial hybrid-polymer aluminium electrolytic capacitors. The B40600* / B40700* series has a capacitance range from 780 µF to 2200 µF and is designed for rated voltages of 25 V and 35 V. It offers extremely low ESR values across the wide temperature range.

“Capacitors in the 63 V voltage class, with capacitance values from 390 µF to 720 µF, are available with the B40640* / B40740* series,” TDK Corporation said.

The aluminium capacitors are manufactured in four can sizes ranging from 14 x 25 mm to 16 x 30 mm (D x H). It is designed for operating temperatures of -55 °C -150 °C and a long service life of 4,000 hours at 125 °C.

Both the series of capacitors are used in automotive and industrial applications including bidirectional converters for 48 V boardnet, motor inverters or hybrid vehicles, electrically-driven power steering systems, pumps, electrical turbochargers and superchargers, radiator cooling fans, gearbox controls and output filters for switch-mode power supplies.

“The inner structure of all axial hybrid-polymer aluminium electrolytic capacitors is optimized for the thermal connection to a heatsink. Thanks to the stable mechanical design, a reliable long-term connection to the heat sink can be achieved, thereby offering excellent heat dissipation,” TDK Corporation said.
