DR73-2R2-R Description

Short technical summary and product information.

The DR73-2R2-R is a shielded drum core wirewound inductor from Eaton - Electronics Division. It offers a nominal inductance of 2.2 µH with a tolerance of ±20%. This inductor is rated for a continuous current of 4.15 A and features a low DC resistance of 16.5 mOhm, contributing to reduced power losses in power supply and filtering applications.

 

Constructed with a ferrite core and fully shielded design, the DR73-2R2-R minimizes electromagnetic interference and is suitable for dense PCB layouts. It has a saturation current rating of 5.52 A, providing headroom for transient current spikes. The component is surface mountable with a compact 7.60 mm x 7.60 mm footprint and a low profile height of 3.55 mm.

 

The operating temperature range spans -40°C to +125°C, allowing use in industrial and automotive environments. The package case is nonstandard, and the inductor is designed for reflow soldering processes. These characteristics make it a reliable choice for DC-DC converters, power management circuits, and energy storage applications.
