AKKN ElectronicsThe Compact Power Challenge
Modern electronics demand components that deliver high current handling without compromising footprint or thermal performance. Traditional inductors struggle with core saturation and efficiency losses above 15A – until EPCOS reshaped the rules.
MKK690-D-25-01 Technical Breakthroughs
- 25A saturation current (Isat) handles 67% higher loads than comparable inductors (EPCOS 2023 Datasheet)
- 0.8mΩ max DCR reduces conductive losses by 32% at 20A operation
- -55°C to +150°C operating range withstands automotive underhood conditions
Three-layer insulated winding technology enables 92% efficiency at 500kHz switching frequencies (verified in Würth Elektronik benchmarking).
Case Studies
1. Fast-Charging EV Stations
ABB integrated MKK690 inductors in 50kW DC converters, achieving:
• 40% smaller magnetic assemblies vs. previous design
• 12% lower junction temperatures at 22A continuous load
• UL-certified operation at 85°C ambient temperatures
2. Collaborative Robotics
KUKA redesigned servo drives using these inductors, demonstrating:
• 28% current ripple reduction in axis controllers
• 1.5kg weight savings per robotic arm
• 0% failure rate through 10,000 thermal cycles (Fraunhofer Institute validation)
