High-Performance Soft Magnetic Toroidal Core with Superior Sendust Alloy

Crafted from premium CS400125 Sendust alloy (Fe-Si-Al), this toroidal core delivers exceptional magnetic permeability (μi: 60-90) and ultra-low core loss (<50 mW/cm³ @100 kHz). Precision-wound for minimal air gaps, ensuring stable inductance under high-frequency operation (up to 1 MHz).

Ideal for Critical Power Electronics Applications

Designed for resonant inductors in LLC converters, high-efficiency transformers, and EMI filters. Perfect for SMPS, solar inverters, and EV charging systems requiring temperature stability (-40°C to +125°C).

Engineered for Bulk Procurement Efficiency

Direct factory pricing with volume discounts for industrial-scale orders. Complies with RoHS and REACH standards. Custom winding/coating options available for OEM integrations.
