DR74-1R0-R Description

Short technical summary and product information.

The DR74-1R0-R is a fixed inductor from Eaton - Electronics Division, featuring an inductance of 1 µH with a tolerance of ±20%. It is a shielded, wirewound drum core inductor using a ferrite core material, designed for surface mount assembly. The component is rated for a continuous current of 5.39 A and has a low DC resistance of 9.9 mΩ, minimizing power losses. The saturation current is specified at 10.2 A, providing headroom for transient currents.

 

The inductor is housed in a nonstandard package with dimensions of 7.60 mm x 7.60 mm x 4.35 mm, suitable for compact power supply designs. It operates over a temperature range of -40°C to 125°C, making it suitable for industrial and automotive environments. The shielded construction helps reduce electromagnetic interference, improving system reliability.

 

Typical applications include DC-DC converters, power supply filtering, and EMI suppression in circuits requiring high current handling. The surface mount package supports automated pick-and-place assembly, reducing manufacturing costs.
