TDK Rolls Out New Snap-In Aluminum Electrolytic CapacitorsFebruary 25, 2021 by Hailey Stewart
TDK Corporation presents the new EPCOS aluminum electrolytic capacitor series B43548* with snap-in terminals. The capacitors feature an excellent maximum ripple current capability of 9.80 A (400 V, 100 Hz, 60 °C). This makes them ideal for demanding applications in power electronics. The capacitors are designed for a maximum operating temperature of 105 °C, have a rated voltage range of 400 V to 500 V and reach under these conditions a useful lifetime of 3000 h. Depending on the rated voltage, they offer a capacitance range of 68 µF to 820 µF in case sizes of 25 mm x 25 mm to 35 mm x 55 mm (d x l). A special feature of the series is the high level of resilience against rapid charging and discharging cycles.
