The CDH125 Series is a wire-wound, SMD Shielded Power Inductor in a 12.5 mm × 12.5 mm package, featuring a 6.0mm height profile. This series is engineered to provide a balanced solution, offering a wide inductance range up to 1000µH (1mH) while maintaining strong current handling.
With saturation currents (Isat) up to 8.0A, the CDH125 is a versatile workhorse for various power supply circuits. Its closed magnetic circuit design effectively reduces leakage flux and EMI, making it suitable for densely packed PCBs. As a leading smd power inductor manufacturer, Magsonder offers this series with an attractive power inductor price point. The CDH125 series, which includes popular values like the 100uh smd inductor (CDH125-101M), offers a higher current rating than conventional inductors of a similar size.
