Eaton Shielded Wirewound Surface Mount Inductor with Ferrite Core 220μH ±20% 1.51A IDC DR125-221-R

Eaton DR125-221-R shielded wirewound surface mount inductor with a ferrite core, offers an inductance of 220μH with a ±20% tolerance and maximum DC current rating of 1.51A. This compact inductor is designed with a 0125 package style, featuring a wirewound construction that ensures high power density and efficiency in demanding electronic circuit applications.

The inductor provides robust performance with a maximum operating temperature of 125°C and a minimum operating temperature of -40°C, making it suitable for a wide range of thermal environments. Its ferrite core material, combined with magnetic shielding, helps minimize interference and enhance stability in sensitive electronic circuits.

With two surface mount pins and a compact size of 12.5mm length, 6mm height, and 12.5mm depth, it is ideal for space-constrained PCB layouts that require reliable inductance. The maximum DC resistance of 384 milliohms ensures efficient current flow while minimizing power loss.

Typical applications include power filtering, noise attenuation in DC-DC converters such as buck, boost, forward, and resonant converters, as well as use in consumer electronics like computers, LCD panels, DVD players, and portable devices. The product complies with RoHS standards, ensuring environmentally sound manufacturing and chemical content.
