The CMKD-0618A Series is a low-profile, high-current SMD Molded Inductor. It is designed with a 7.0 mm × 6.6 mm footprint and a slim 1.8mm profile, making it an excellent solution for high-density, height-constrained power applications.
This series leverages a one-piece, magnetically shielded construction to minimize EMI and core loss. It delivers a strong saturation current (Isat) of up to 18.0A and is optimized for high-frequency (up to 5MHz) DC-DC converters. It is an ideal choice for notebook regulators, SSD modules, and other compact power circuits. The CMKD-0618A's advanced design, like its inductor symbol, represents efficiency and power density. As one of the top inductor manufacturers, Magsonder's power inductor definition focuses on reliability and performance, both embodied in the CMKD-0618A SMD Molded Inductor.

Notes:
Test Conditions: All test data is referenced to 25°C ambient.
Operating Temperature Range: -55°C to +125°C (ambient plus self-temperature rise).
Isat (Saturation Current): DC current (A) that will cause L₀ to drop approximately 30%.
Idc (Rating Current): DC current (A) that will cause an approximate ΔT of 40°C.
Temperature Limit: The part temperature (ambient + temp rise) should not exceed 125°C under worst-case operating conditions.
