The Silent Hero in High-Power Applications
In the bustling city of Shenzhen, engineers at a leading EV charging station manufacturer faced a critical challenge: their 400V DC fast chargers kept overheating during peak hours. The culprit? Underperforming capacitors. After switching to EPCOS 43310-S9688-A2 6800μF/400V electrolytic capacitors, they achieved a 40% reduction in thermal losses and extended operational lifespan by 15,000 hours – equivalent to 5+ years of continuous service.
Built for Extreme Conditions
This TDK Group-engineered component isn’t your average capacitor. With a 105°C endurance rating (5000h per IEC 60384-4) and 25mm ultra-low ESR, it’s become the go-to solution for:
- Solar inverters handling 1500V DC systems
- Industrial motor drives requiring 100A+ surge currents
- High-speed railway power converters
Real-World Impact in Renewable Energy
When a 50MW wind farm in Inner Mongolia upgraded their converters with 43310-S9688-A2 units, they recorded:
| Energy Loss Reduction | 22% |
| Maintenance Intervals | Extended from 6 to 18 months |
| Capacitor Failure Rate | 0.03% (industry average: 1.2%) |
Why Engineers Choose This Component
Unlike standard capacitors that bulge under pressure, the 43310-S9688-A2 features:
- Self-healing electrolyte technology
- Vibration-resistant can design (tested to 15G)
- ±20% capacitance tolerance from -40°C to +85°C
As we enter the era of 800V electric vehicles and 2000V solar arrays, components like this EPCOS capacitor aren’t just parts – they’re enablers of our electrified future.
