The CDH104 Series is a wire-wound, SMD Shielded Power Inductor in a 10.5 × 10.5 mm footprint. With a low profile of 4.8mm, this series is designed for power applications where board space and component height are key considerations. As a shielded inductor, its closed magnetic circuit design reduces leakage flux and minimizes Electromagnetic Interference (EMI).
This component offers a higher current rating than conventional inductors of a similar size. The CDH104 provides a wide inductance range from 4.7µH up to 470µH, with saturation currents (Isat) up to 3.2A. As a leading power inductor manufacturer, Magsonder has designed this SMD Shielded Power Inductor for reliability in various power supply circuits. The CDH104 is an essential component for energy storage and filtering; if you're asking what is an inductor used for, this series is a perfect example of a high-performance power solution.

Notes:
Test Conditions: All test data is referenced to 25°C ambient.
Operating Temperature Range: -40°C to +125°C (ambient plus self-temperature rise).
Idc (Rating Current): DC current (A) that will cause an approximate ΔT of 40°C.
Isat (Saturation Current): DC current (A) that will cause L₀ to drop approximately 35%.
Temperature Limit: The part temperature (ambient + temp rise) should not exceed 125°C under worst-case operating conditions.
