EPCOS / TDK B25648A ModCap UHP Power Capacitors
EPCOS / TDK B25648A ModCap Ultra-High Performance (UHP) Power Electronic Capacitors enable continuous operation at hotspot temperatures of up to +105°C without power derating. Compared to previous ModCap generations, which required derating starting at +90°C, the design of the EPCOS / TDK B25648A enables higher current density and a longer lifetime in challenging conditions. By combining a high-temperature dielectric with a modular design, the ModCap UHP series extends the lifetime of capacitors to 200,000 hours at +105°C and supports a 20% higher current density. With a voltage rating of 1350VDC to 1800VDC and a capacitance range of 470µF to 880µF, the series is optimized for SiC semiconductor-based inverters that require low inductance (ESL of 8nH) and high-frequency performance.
These ModCap capacitors target renewable energy (solar and wind power, electrolyzers), energy storage, and inverters for railway and industrial drives. The cubic design (205mm length x 90mm width x 170mm height) simplifies busbar integration, increasing power density in compact converters and reducing the need for additional snubber capacitors.
