Powering Heavy-Duty Applications with Precision
The EPCOS B43584-S5478-Q2 4700μF/450V aluminum electrolytic capacitor stands as a cornerstone component in modern industrial power systems. With its 105°C endurance rating and 18,000-hour lifespan at 85°C (per TDK technical documentation), this robust capacitor addresses critical energy storage challenges in harsh environments.
Key Features Driving Industrial Adoption
- 4700μF ±20% capacitance tolerance
- 450V DC rated voltage
- 40mm diameter x 80mm height compact design
- 6.3A ripple current at 100Hz/105°C
Real-World Implementation: Wind Turbine Converter Case
In a 2022 installation at a German wind farm, 32 units of B43584-S5478-Q2 capacitors were deployed in medium-voltage converter systems. The configuration demonstrated:
- 98.7% voltage stability during 15m/s gust loads
- 0.02% annual failure rate over 18,000 operational hours
- 30% reduction in maintenance cycles compared to previous solutions
Technical Advantages for Power Electronics
Engineers particularly value the capacitor’s self-healing electrolyte formulation, which extends service life in variable load scenarios. When used in UPS systems, field tests show 12% better surge absorption than industry averages (IEC 61000-4-5 compliant).
Cross-Industry Application Spectrum
| Industry | Use Case | Performance Benefit |
|---|---|---|
| EV Charging Stations | DC Link Circuits | 15% faster charge cycles |
| Industrial Lasers | Pulse Power Supplies | ±1.5% energy consistency |
| Solar Inverters | DC Bus Filtering | 3% efficiency gain |
As power densities continue rising, the B43584-S5478-Q2 remains a preferred choice for engineers balancing space constraints with reliability demands. Its THB series construction ensures stable performance even in -40°C to +105°C thermal extremes, making it indispensable for mission-critical applications.
