Why EPCOS B43564-S9658-M2 is the Go-To Capacitor for Heavy-Duty Systems?
When engineers at a German solar inverter manufacturer needed capacitors capable of handling 400V systems with 98%+ efficiency requirements, they turned to the EPCOS B43564-S9658-M2. This 6500μF aluminum electrolytic capacitor became the backbone of their 100kW commercial PV inverters, surviving 15,000+ operational hours in temperature-cycling tests from -40°C to +105°C.
Technical Specifications That Matter
- Ripple current: 12.3A @ 100Hz
- Endurance: 5000h @ 105°C (IEC 60384-4)
- Dimensions: 76.5mm (D) × 140mm (H)
In EV charging stations across Scandinavia, these capacitors demonstrate 2.8% lower energy loss compared to standard models during 50kW fast-charging cycles – a crucial advantage when operating in -30°C winters.
Real-World Performance Metrics
| Application | Performance Gain |
|---|---|
| Industrial UPS Systems | 23% longer hold-up time |
| Wind Turbine Converters | 15% reduction in thermal stress |
Maintenance data from 150+ industrial motor drives shows the B43564-S9658-M2 achieves 7-year service intervals – 40% longer than industry averages for 400V DC link capacitors.
