■ Feature:
1. By using powder-compressed magnetic cores with higher saturation flux density, the toroidal coil inductor can be effectively applied to suppress surge noise such as that generated during thyristor startup or other abrupt high-current noise.
2. Due to the relatively larger loss coefficient, compared to inductors using traditional ferrite cores, toroidal coil inductor can achieve equivalent noise absorption characteristics with a smaller volume and fewer winding turns.
■ Applications:
PFC, Televisions, VCR, OA equipment, PC, Other electronic equipment, etc.
■ Product Overview
The LGH2711-22uH differential mode inductor is a high-performance, toroidal coil inductors are designed specifically for Differential Mode (DM) noise suppression in power conversion circuits. Featuring a compact radial leaded package, this component utilizes a high-saturation magnetic powder core to deliver 22µH of inductance with excellent current handling capability and minimal electromagnetic interference (EMI) radiation.
Engineered for demanding environments, toroidal coil inductor is an ideal choice for filtering high-frequency switching noise in AC/DC and DC/DC power supplies, ensuring compliance with stringent EMC standards.
