Most sizes of our Amorphous C-Cores are in stock and available for same day shipping.
Applications
- Transformer cores in switch mode power supplies at 400 – 20,000 Hz
- Transformers for Inverters in Welding Equipment, Wind Turbines, and Solar Panels
- Output Filter Chokes in Large Switching Mode Power Supplies
- UPS harmonic inductors
- High power ballasts
- Power Factor Correction Chokes in UPS
