30 Working DaysDongguan JH Amorphous' Toroidal Coating Nanocrystalline Cores are engineered for precision electromagnetic interference (EMI) suppression and high-efficiency inductive components. With a compact toroidal geometry and uniform nanocrystalline microstructure, these cores offer outstanding magnetic performance across a wide frequency range, especial for high-frequency, making them ideal for high-end power electronics, automotive, industrial, and renewable energy applications.
Ultra-high Permeability
Permeability values exceeding 80,000 – ideal for compact, space-efficient choke designs.
Exceptional Low Core Loss
Significantly lower than ferrite or amorphous materials at low and medium frequencies.
Excellent Thermal Stability
Operates reliably from –40°C to +140°C, with stable performance under thermal cycling.
Low Magnetostriction
Minimizes audible noise and mechanical stress, improving device lifespan and user comfort.
Durable Coating
Epoxy or polyester coatings provide insulation, corrosion resistance, and mechanical protection.
Compact Toroidal Shape
Offers minimal magnetic leakage, easy coil winding, and excellent field symmetry.
Common Mode Chokes
Superior EMI filtering in compact footprints for industrial drives, SMPS, and solar inverters.
Inductors & Transformers
Suitable for differential mode inductors, flyback transformers, and push-pull converters.
EV/HEV Onboard Chargers
High thermal and electrical stability make it ideal for automotive-grade EMI solutions.
Smart Meters / Energy Systems
For precision current sensing and compact magnetic components.
