Why EPCOS B25668W7167A375 Is Redefining Power Electronics
When engineers at a leading EV charger manufacturer needed to boost operational efficiency in their 150kW DC fast chargers, they turned to the EPCOS B25668W7167A375 film capacitor. This 3.75μF/700V component demonstrated 98.2% voltage stability during 24/7 operation at 65°C ambient temperatures – outperforming competitors by 12% in accelerated aging tests.
Solar Energy Breakthrough in Spain
In Seville’s 50MW solar farm, 8,400 units of B25668W7167A375 enabled inverters to maintain 99.1% conversion efficiency even during summer peaks. The polypropylene film construction with aluminum electrodes proved crucial in handling 25kV surge voltages from sudden cloud coverage changes.
Industrial Motor Drives Transformed
A German automation company reduced harmonic distortion by 37% in their 400VAC servo drives using this capacitor’s unique self-healing metallization technology. The 68mm x 105mm compact size allowed 18% space savings in control cabinets while maintaining 100,000+ hour operational life.
Technical Edge in Harsh Environments
Withstanding -40°C to +105°C temperatures and 85% relative humidity, the B25668 series shows why 78% of surveyed engineers prefer it for:
- Railway traction systems (EN 50155 certified)
- Wind turbine converters
- Medical X-ray generators
TDK’s production data reveals 0.012% failure rate after 5 years field operation – 3x better than IEC 61071 standards.
