Edge® Cores

Designed for cutting edge performance, Edge® cores offer the best DC bias of all alloy powder cores. When compared with High Flux, Edge displays approximately 40% lower losses and 30% improvement in DC bias. Applications include Rack Mount Power Supplies, Telecom Servers, Switching Regulator Inductors, In-Line Noise Filters, Flyback Transformers, Power Factor Correction (PFC), and Pulse Transformers. Choose Edge for highest efficiency.
