Product Features
Original AS777026 Core Geometry: Utilizes a massive 3-inch (77.8mm) toroidal core, providing large effective cross-sectional area to handle extreme magnetic flux without saturation
Sendust (Kool Mu) Material: Constructed with high-permeability Fe-Si-Al alloy powder, ensuring ultra-low core losses at high frequencies (up to 100kHz) and "Soft Saturation" profile
Heavy-Gauge Winding: Wound with high-purity, high-temperature enameled copper wire or flat copper busbars to minimize DC Resistance (DCR) and maximize current-carrying capacity
Low Radiated EMI: Naturally closed-loop toroidal shape effectively contains magnetic field, preventing electromagnetic interference with adjacent control circuits or communication lines
