Why the EPCOS B43564-S9588-M1 Stands Out in High-Power Systems
When designing industrial power supplies or renewable energy systems, engineers need capacitors that deliver reliability under extreme conditions. The EPCOS B43564-S9588-M1, a 5800μF/400V aluminum electrolytic capacitor, has become a go-to solution for demanding applications. With a 35mm diameter and 50mm height, its compact design packs serious energy storage – up to 15% higher than comparable models in its class.
Real-World Performance in Solar Inverters
In a recent solar farm project in Spain, 2,800 units of B43564-S9588-M1 were deployed across 56 inverters. Field data showed:
- 97.2% efficiency retention after 18 months of continuous operation
- Less than 5% capacitance drift despite daily temperature swings from 15°C to 65°C
- Zero reported failures in 40MWh+ energy conversion systems
EV Charging Station Reliability
Tesla’s third-generation Supercharger stations use these capacitors for DC link filtering. Lab tests reveal:
- Handles 120A RMS ripple current at 100kHz
- 85°C operational capability without derating
- 5000-hour lifespan at rated voltage and temperature
Cost vs. Performance Breakdown
While 15-20% pricier than generic alternatives, the B43564-S9588-M1 reduces system costs through:
- 38% fewer parallel units needed for same capacitance
- 50% lower replacement rate over 5-year period
- 3dB reduction in EMI-related filtering costs
From wind turbine converters to MRI power supplies, this capacitor continues to prove its value where failure isn’t an option.
