TDK Offers Two New Series of Capacitors

TDK Corporation has extended its product range of hybrid-polymer aluminum electrolytic capacitors and now offers two series with an axial design.

TDKThe B40600* / B40700* series is designed for rated voltages of 25 V and 35 V. These cover a capacitance range from 780 µF to 2200 µF. Capacitors in the 63 V voltage class with capacitance values from 390 µF to 720 µF are available with the B40640* / B40740* series.

The capacitors are produced in four can sizes ranging from 14 x 25 mm to 16 x 30 mm (D x H). These are available in an axial-lead design (B406*) or as a solder star version (B407*), providing a wide variety of mounting options.

The inner structure of all axial hybrid-polymer aluminum 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. For designs with heat sinks, versions without shrink-on sleeves are offered in both series, while for freestanding assembly, components with a PET shrink-on sleeve are available.

Both series are designed for a wide range of operating temperatures from -55 °C to 150 °C with a useful life of 4000 hours at 125 °C. The great advantage of hybrid-polymer technology is its extremely low ESR values across the wide temperature range. For example, with a can size of 16 x 30 mm and an ambient temperature of 20 °C, an ESR of 3.5 mΩ can be achieved.

These capacitors are typically used in automotive and industrial applications. Examples include 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.
