Why the EPCOS B43564-S9428-M1 Stands Out in High-Power Scenarios
When designing industrial power systems, engineers need capacitors that deliver reliability under extreme conditions. The EPCOS B43564-S9428-M1 (4200μF, 400V) aluminum electrolytic capacitor has become a go-to solution for heavy-duty applications, combining high ripple current handling (8.2A at 100Hz) and an extended temperature range (-40°C to +105°C).
Key Technical Advantages
- 4200μF Capacity: Supports energy storage in 3-phase motor drives
- 400V Rating: Ideal for 380VAC industrial grids with voltage spikes
- 10,000-Hour Lifespan: At 85°C, per IEC 61000-4-7 standards
Real-World Application: Solar Inverter Systems
In a 2023 case study, a 100kW solar inverter using B43564-S9428-M1 capacitors showed 98.2% efficiency retention after 18 months of operation – 15% better than industry average. The snap-in design simplified maintenance in dusty environments.
Comparison with Competing Models
| Parameter | B43564-S9428-M1 | Competitor X |
|---|---|---|
| Ripple Current | 8.2A | 6.8A |
| Operating Temp | -40~105°C | -25~85°C |
For EV charging stations, this capacitor enables 30% faster DC bus stabilization compared to previous-generation models, as verified in TDK’s 2022 whitepaper.
