Powering Heavy-Duty Systems with Precision
When engineers at a German automation equipment manufacturer needed capacitors for 500kW motor drives, they tested 7 models before choosing EPCOS B43456-A5338-M. Why? This 530μF aluminum electrolytic capacitor delivered 98.3% voltage stability at -25°C to +85°C environments – 15% better than competitors in surge current tests.
Solar Farm Stability Secret
In Spain’s 200MW photovoltaic plant, 8,200 B43456-A5338-M units handle DC link filtering in inverters. Field data shows 0.02% annual failure rate – critical when servicing panels on 50m-high trackers. The capacitor’s 5,000-hour @105°C lifespan translates to 12+ years in real-world conditions.
EV Charger Manufacturers’ Edge
A leading EV charger producer reduced warranty claims by 40% after switching to this TDK subsidiary’s product. The secret lies in its 35mm×50mm compact size handling 450VDC nominal voltage, enabling 25% more power density in charging cabinets.
Technical Highlights
- Ripple current: 8.9A @100Hz
- ESR: 23mΩ @20°C
- Operating temp: -40°C to +105°C
With 63% of industrial buyers prioritizing long-term reliability over initial cost (2023 B2B Electronics Survey), the B43456-A5338-M’s 5-year MTBF makes it a strategic choice for mission-critical systems.
