DR74-220-R Description

Short technical summary and product information.

The DR74-220-R is a fixed inductor from Eaton's DR74 series, featuring a shielded drum core wirewound construction. It offers an inductance of 22µH with a tolerance of ±20% and is rated for a continuous DC current of 1.75A. The DC resistance is 92.5mOhm, and the saturation current is 2.13A.

 

This inductor is designed for surface-mount assembly in a nonstandard 7.60mm x 7.60mm package with a height of 4.35mm. The ferrite core material provides effective magnetic shielding, reducing electromagnetic interference. It is suitable for power supply and DC-DC converter applications where stable inductance and current handling are required.

 

The component operates over a wide temperature range of -40°C to 125°C, making it suitable for industrial and automotive environments. The DR74-220-R is RoHS3 compliant and REACH unaffected, though these compliance claims are unverified.
