■ Feature:
1. By using powder-compressed magnetic cores with higher saturation flux density, the differential mode 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, differential mode inductor can achieve equivalent noise absorption characteristics with a smaller volume and fewer winding turns.
■ Toroidal Inductor Applications:
PFC, Televisions, VCR, OA equipment, PC, Other electronic equipment, etc.
■ Product Overview
The LGH1807-100uH differential mode inductor is a high-efficiency toroidal inductor specifically engineered for differential mode noise suppression in power electronics. Utilizing a closed-loop toroidal (doughnut-shaped) magnetic core, this component offers superior magnetic field containment, minimizing EMI radiation and cross-talk. The 100 microhenry (µH) value is optimized for filtering common-mode and differential-mode interference in a wide range of applications.

■ Technical Advantage
Toroidal Core Structure
Toroidal inductor provides a closed magnetic path, resulting in high inductance per volume, low electromagnetic interference (EMI), and high Q factor.
Differential Mode Operation
Differential mode inductor effectively suppresses noise currents flowing in opposite directions on the supply lines, ideal for input/output filtering.
High Saturation Current
Toroidal inductors are designed to handle high DC bias currents with minimal inductance drop, ensuring stable performance under load.
Low Core Losses
Ferrite or specialized alloy core material reduces hysteresis and eddy current losses, improving overall efficiency.
Tinned Copper Leads
Enables easy soldering to PCBs and provides excellent electrical conductivity.
Compact Size (LGH1807)
Differential mode inductor with 18.0mm x 7.0mm footprint saves valuable board space while delivering high power density.
■ Applications
PFC, Televisions, VCR, OA equipment, PC, Other electronic equipment, etc.
