TDK new 125 V and upgraded 63 V aluminum electrolytic capacitors for battery systems
TDK Corporation has expanded its aluminum electrolytic capacitor portfolio with new 125 V versions of the B43693/B43793 series and upgraded the 63 V B41687/B41787 series. These vibration-resistant capacitors are optimized for compact DC-link banks in 48 V to 120 V battery systems used in small electric vehicles, micromobility, forklifts, electric boats, humanoid robots, and industrial equipment.

The 125 V series allows higher DC-link voltages with a single capacitor, eliminating the need for series connection. This reduces component count and simplifies bank design. Mounting the capacitors to a heat sink can more than double their ripple current capability (example: an 18 × 30 mm capacitor rated 5.2 A at +105°C ambient can handle 11.1 A when the case is held at +105°C).
With low ESR, high ripple current handling, and robust vibration resistance, these capacitors help reduce power losses, improve thermal performance, and enable smaller, more cost-effective DC-link designs.
