Why EPCOS B43564-S9578-M1 Stands Out in Industrial Power Solutions
With 5700μF capacitance and 400V voltage rating, the EPCOS B43564-S9578-M1 aluminum electrolytic capacitor has become a preferred choice for engineers designing high-power systems. This radial leaded component features a compact 51mm diameter x 80mm height package, making it suitable for space-constrained applications.
Core Technical Specifications
- Rated capacitance: 5700μF ±20%
- Voltage range: 400V DC
- Operating temperature: -40°C to +85°C
- Endurance: 5,000 hours at 85°C
Real-World Application Cases
In UPS systems for data centers, this capacitor demonstrates exceptional performance. A 2022 field test showed 34% lower equivalent series resistance (ESR) compared to standard models, resulting in 15% longer backup time during power outages. For industrial motor drives, its ripple current capability (8.3A @ 100Hz) ensures stable operation in CNC machines and robotic arms.
Renewable Energy Implementation
Solar inverter manufacturers report 98.2% reliability when using B43564-S9578-M1 in DC-link circuits. The capacitor’s self-healing oxide layer maintains performance through 200,000+ charge cycles, critical for 24/7 solar farms. A wind turbine converter project achieved 2.5% higher energy conversion efficiency using this component compared to previous designs.
Maintenance and Selection Tips
While the capacitor boasts a 10-year design life under normal conditions, engineers should monitor operating temperature. Proper derating (80% voltage margin) extends service life by 30% according to EPCOS lab tests. When replacing older capacitors, verify PCB spacing – the 51mm diameter requires at least 55mm clearance for optimal heat dissipation.
