Extended Range B40600* Series Capacitors

TDK Corporation has extended its product range of hybrid-polymer aluminum electrolytic capacitors and offers the B40600* series with an axial design. The B40600* series is designed for rated voltages of 25 V and 35 V and covers a capacitance range from 780 µF to 1700 µF.

The capacitors are produced in four can sizes ranging from 14 mm x 25 mm to 16 mm x 30 mm (D x H) and are available in an axial-lead design. The inner structure of all axial hybrid-polymer aluminum electrolytic capacitors is optimized for the thermal connection to a heat sink. 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, and for freestanding assembly, components with a PET shrink-on sleeve are available.

The B40600* series is 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 mm x 30 mm and an ambient temperature of +20°C, an ESR of 3.5 mΩ can be achieved.
