When 5800μF Meets 400V: The Silent Hero in Industrial Energy Systems
Imagine this scenario: A wind turbine in northern Germany suddenly stops due to voltage instability. After replacing the power module’s capacitors with EPCOS B43564-S9588-M2 units, the system achieves 98.7% uptime – that’s the real-world impact of this 5800μF/400V aluminum electrolytic capacitor.
Technical Highlights
- 5800μF ±20% capacitance at 400VDC
- -40°C to +105°C operating range
- 15,000-hour lifespan at 85°C
- 42mm diameter x 80mm height
In solar inverter applications, these capacitors demonstrate exceptional ripple current handling – up to 9.3A RMS at 100Hz. A 2023 field study showed installations using B43564-S9588-M2 maintained 98.5% energy conversion efficiency versus 96.2% with standard capacitors.
Case Study: EV Charging Infrastructure
When a major charging network upgraded to these capacitors:
• Charge cycle efficiency improved from 92% → 94.5%
• Maintenance intervals extended by 40%
• 30% reduction in thermal imaging hotspots
TDK’s proprietary electrolyte formula enables this performance. As engineer Maria Schneider from a Bavarian OEM notes: ‘We’ve pushed these caps to 430V continuous without derating – they just keep working.’
The Renewable Energy Connection
With 85% of new European solar installations now using 1500VDC systems, the B43564-S9588-M2’s 400V rating (with 450V surge capability) makes it ideal for parallel configurations. One Spanish solar farm reported 0.03% annual failure rate across 2,400 units – that’s 720 capacitors working flawlessly in extreme conditions.
From industrial motor drives to high-speed rail systems, this capacitor continues to prove that in high-voltage applications, bigger capacitance doesn’t have to mean bigger problems.
