DR73-220-R Description

Short technical summary and product information.

The DR73-220-R is a shielded drum core wirewound fixed inductor manufactured by Eaton - Electronics Division. It offers 22 µH inductance with ±20% tolerance and is rated for 1.62 A continuous current, with a saturation current of 1.67 A. The component has a DC resistance of 107 mΩ and operates over -40°C to 125°C.

 

The inductor uses a ferrite drum core with wirewound construction and is fully shielded to contain magnetic flux. It is supplied in a nonstandard surface-mount package measuring 7.60 mm x 7.60 mm with a 3.55 mm height, suitable for automated PCB assembly.

 

With its compact footprint and low profile, the DR73-220-R is suited for power conversion and filtering circuits in space-constrained designs. The shielded construction helps minimize electromagnetic interference in sensitive electronic systems.
