The CDH124 Series is a large, wire-wound, SMD Shielded Power Inductor. It features a 12.5 mm × 12.5 mm footprint combined with a slim 4.5mm maximum height, offering high power density for applications where vertical space is limited.
Engineered for robust power supply circuits, the CDH124 series provides excellent current handling, with saturation currents (Isat) up to 6.5A. Its closed magnetic circuit design, characteristic of smd shielded inductors, minimizes leakage flux and EMI. This makes it a reliable choice for high-current applications, including automotive systems and servers. The popular 10uh smd inductor value (CDH124-100M) in this series, for example, supports 4.5A saturation current. The CDH124 is a leading high current smd power inductor for modern electronics.

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.
