Cylindrical-Shaped Compact B32320I DC Link Capacitors with Low ESL for PCB Mounting
TDK Corporation has lately released new B32320I series of compact cylindrical DC-link capacitors for mounting on PCBs. Each device in the series is designed for voltages of 450 V DC to 1300 V DC and comes with a capacitance range of 6.5 µF to 260 µF. These DC-link capacitors are designed for a maximum hotspot temperature of 105 °C. The current handling capacity of IRMS is up to 27.6 A (10 kHz, 60 °C) and the minimal ESR is 2.4 mΩ.
Measuring 35 mm x 53 mm and 60 mm x 120 mm, these devices come with plastic housing that corresponds to UL 94 V-0. The tall insertion height of these new DC-link capacitors enables them to meet low footprint requirements on the PCB in relation to their capacity.
The devices in the new series feature five pins ensuring high current capability as well as high stability on the PCB. These devices can be used as frequency converters for drives, converters for photovoltaic and air conditioning systems, and critical UPS systems.
