Small SMT power inductors offer low DCR

The CDMT40D20 series power inductor uses metal-hybrid construction that provides effective magnetic shielding with lower DC resistance. The 4.3 x 4.3 x 2.1-mm inductors come with values from 0.27 to 4.70 µH at 100 kHz.

Saturation current at –30% is 17.2 to 3.70 A with DC resistance of 5.80 to 59.0 mΩ, typical. Operating temperature range is –40°C to 125°C, ambient. An example part number for a 0.68-µH part is CDMT40D20HF-R63NC. $1.08 ea/500.
