The CDH74 Series is a wire-wound, SMD Shielded Power Inductor that offers high performance in a standard profile. It features a 7.3 mm × 7.3 mm footprint and a 4.5mm height, a design that supports an extremely wide inductance range, from 1.0µH all the way to 1000µH (1mH).
This series delivers a strong saturation current (Isat) of up to 6.8A and utilizes a closed magnetic circuit design to minimize EMI. Its combination of strong current, low EMI, and an extensive value range makes it a highly versatile high current inductor for a majority of DC-DC converter applications. As a leading inductor supplier, Magsonder designed the CDH74 to be an ideal choice for power inductors for smps (Switch-Mode Power Supplies).

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.
