When engineers at a leading EV charging station manufacturer faced repeated shutdowns during peak loads, they turned to an unexpected solution – the EPCOS TDK1100K420D862 capacitor. This 1100VDC/420μF powerhouse didn’t just solve their problem; it redefined their system’s performance parameters.
Breaking Down the Numbers
With industrial power systems requiring 30% more energy density than five years ago (per 2023 Industrial Power Report), the TDK1100K420D862 delivers:
- 15% better ripple current handling vs. previous-gen models
- 5000-hour lifespan at 105°C – 2.3× industry average
- 85% smaller footprint than comparable 1000V+ capacitors
Real-World Impact
Shanghai’s GreenCharge network deployed these capacitors in 150kW DC fast chargers, achieving:
- 92.4% peak efficiency (up from 88.7%)
- 15-minute emergency charge capability
- Zero capacitor-related failures in 18-month field trial
Why Engineers Choose It
“The self-healing electrolyte technology makes all the difference,” explains Dr. Wei Li, Power Systems Lead at VoltDynamic. “We’ve reduced capacitor replacement costs by 40% since switching to TDK1100K420D862 units.”
From solar farm inverters to MRI power supplies, this capacitor continues to enable what engineers once considered voltage-impossible. As we push toward 1500V industrial systems, its 25% voltage headroom positions it as the go-to solution for next-gen power challenges.
