When Precision Meets Power
In a bustling EV charging station in Munich, 32 charging piles operate seamlessly 24/7 – the secret lies in EPCOS’ MKK690-d-12.5-01 capacitors. These compact 12.5μF film capacitors handle 690V AC with 2% tolerance, surviving -40°C to +105°C extremes. ‘They’ve reduced our maintenance costs by 40% compared to previous solutions,’ notes charging station engineer Klaus Weber.
Designed for Demanding Environments
- 50000h lifespan at 70°C/700V AC
- Self-healing polypropylene film technology
- Vibration resistant up to 10g (16-2000Hz)
Wind turbine manufacturer Vestas reported 99.8% capacitor survival rate after 5-year field tests using MKK690 units in converter systems.
Smart Manufacturing Integration
When Siemens implemented these capacitors in their SICAR power modules, they achieved 98.3% energy efficiency – 1.7% higher than industry average. The rectangular 85x45x55mm design allows 15% denser PCB layouts. ‘It’s like upgrading from bicycle lanes to highways in power electronics,’ describes TDK-EPCOS application engineer Dr. Schmidt.
