DR73-221-R Description

Short technical summary and product information.

The DR73-221-R is a fixed inductor from Eaton - Electronics Division. It is a shielded drum-core, wirewound component with a ferrite core, offering 220 µH inductance and ±20% tolerance. The part is rated for 520 mA DC current and has 1.05 Ω DC resistance.

 

This surface-mount inductor operates across -40°C to +125°C and comes in a nonstandard package measuring 7.60 mm x 7.60 mm with a height of 3.55 mm. The shielded construction helps reduce electromagnetic interference, and the ferrite core supports stable inductance in power circuits.

 

Typical uses include power supply filtering, DC-DC converter output stages, and general-purpose energy storage in compact electronic assemblies.
