When Reliability Meets High-Current Demands
In a solar farm project in Arizona, engineers faced recurring capacitor failures in 500kW inverters during peak afternoon operations. The solution came with EPCOS B43564-S9528-M1 capacitors – 5200μF/400V aluminum electrolytic units that reduced temperature-related failures by 68% compared to previous components, according to 2022 field test reports.
Built for Extreme Conditions
This capacitor’s +105°C rating and 18,000-hour lifespan at maximum temperature make it ideal for:
- Wind turbine converters (3,000+ units deployed in North Sea installations)
- EV fast-charging stations (30% smaller footprint vs. conventional designs)
- Industrial UPS systems (95.2% efficiency maintained after 5,000 charge cycles)
The Ripple Current Advantage
With 12.3A ripple current handling at 100Hz, the B43564-S9528-M1 outperforms standard 400V capacitors by 40%. A CNC machinery manufacturer reported 22% reduction in harmonic distortion after upgrading to these capacitors in their motor drives.
Smart Integration Features
The capacitor’s 77.5mm height and snap-in design enabled a Chinese EV maker to increase power density by 1.8× in their latest onboard charger module. Maintenance teams appreciate the pressure relief vent’s 360° protection – a critical feature in crowded electrical cabinets.
As renewable energy projects demand 20% annual growth in high-voltage capacitor supplies (per MarketsandMarkets 2023 report), the B43564-S9528-M1 stands ready to power tomorrow’s energy revolution.
