When 800V Pushes Harder, Stability Becomes a Design Decision. As EV on-board chargers move toward higher voltages and currents, DC link capacitors must deliver uncompromising performance - without increasing system size or complexity.
With these two new series, we introduce compact aluminium electrolytic capacitors engineered specifically for modern EV charging platforms.
These capacitors help engineers to:
Handle higher ripple currents reliablyReduce footprint while maintaining performanceImprove efficiency in high-power OBC designsEnsure long lifetime even at +105 °CEnable future-ready 800 V charging architectures
Qualified to AEC-Q200 and integrated into TDK’s AlCap Useful Life Calculation Tool, they support faster, more confident system design.

Power Density Without Oversizing. Built for +125°C. Next-generation power electronics, whether in xEV traction inverters, onboard chargers, or industrial converters, are pushing DC link designs to their thermal limits. That’s exactly where the B3271xP DC link film capacitors are engineered to perform.
Designed for operation up to +125 °C and no derating up to +105 °C, the B3271xP series delivers stable capacitance, high ripple current capability, and long-term reliability even in tightly packed, high-power environments. Low ESR, robust self-healing MKP dielectric, and automotive-grade compliance make it a solid foundation for demanding inverter architectures.

When Material Costs Spike, Engineering Decisions Matter. Silver prices have surged and with them, the cost and risk profile of conventional piezo designs. But what if the solution isn’t about managing volatility… but eliminating dependency altogether?
At TDK, we’re taking a different route:Replacing silver with copperStabilizing cost structuresIncreasing reliability in humid environments
Our copper-based HAS technology doesn’t just respond to market pressure, it redefines the baseline for performance, durability, and scalability across applications like nano-positioning in semiconductor manufacturing, in medical drug delivery, and in AI infrastructure.
The real question isn’t how to cope with rising silver prices. It’s how to design beyond them.

85 °C is not enough for next-generation DC Link Design!
Power electronics are evolving faster than ever and conventional DC link capacitors are starting to hold engineers back.
At the heart of this shift: wide-bandgap semiconductors (like SiC and GaN) that demand higher power density, elevated temperatures, and ultra-fast switching on next-generation converters.
Traditional film capacitor tech struggles under these conditions. That’s why we developed the ModCap UHP series.
Built around a newly engineered high-temperature dielectric, ModCap UHP delivers:Continuous operation at +105 °C without deratingUp to 20 % higher current density and more compact DC link designsOutstanding thermal stability and reliability in the toughest environments
Whether it’s renewable energy, industrial drives, or SiC power modules, this breakthrough lets designers push performance without compromise.
