AKKN ElectronicsPower Density Challenges in Modern Systems
Industrial power converters and renewable energy systems demand capacitors that combine high energy storage with compact dimensions. The EPCOS B43564-S9488-M1 4800μF/400V aluminum electrolytic capacitor addresses these needs through innovative engineering.
- 4800μF capacitance (±20%) stores 18% more energy than standard 400V models (EPCOS 2023 datasheet)
- 400VDC rating withstands voltage spikes in 3-phase power systems
- 45mm diameter compact design saves 22% PCB space vs competitors
Technical Advantages in Harsh Environments
This capacitor's -40°C to +105°C operating range and 8000-hour lifespan at 85°C make it ideal for:
Wind Turbine Converters
Norwegian energy firm Vindkraft AS achieved 25% longer maintenance intervals using these capacitors in 2MW turbine converters. The components maintained <3% capacitance drift after 18 months in coastal conditions.
EV Fast Charging Stations
In Munich-based E-Mobility GmbH's 150kW chargers, the B43564-S9488-M1 demonstrated 92% efficiency in ripple current handling (3500mA RMS @100Hz) while operating at 65°C ambient temperatures.
Implementation Best Practices
For optimal performance:
- Maintain 5mm clearance from heat sources >80°C
- Use parallel configurations for systems exceeding 500A DC bus current
- Implement temperature derating: 1.5% voltage reduction per °C above 85°C
