Sendust Core 10uH-10mH DIP Through Hole PFC UPS Choke Coil Toroidal Power Inductor
The AS777026 10uH Heavy-Duty Toroidal Inductor is an industrial-grade magnetic component specifically designed for high-efficiency energy storage in Power Factor Correction (PFC) and boost converter stages. Built upon the industry-standard AS777026 Sendust core, this inductor is optimized for high-power environments where continuous DC current exceeds 100A. It serves as a robust solution for 10kW to 50kW power modules, providing stable inductance and low losses required for modern high-density power electronics.

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
