DR74-4R7-R Description

Short technical summary and product information.

The DR74-4R7-R is a fixed inductor manufactured by Eaton - Electronics Division. It features an inductance of 4.7µH with a tolerance of ±20%. The component is rated for a continuous current of 3.34A and has a DC resistance of 25.4mOhm. The saturation current is 4.37A. This inductor is shielded and uses a drum core wirewound construction with a ferrite core material. It is designed for surface mount assembly and comes in a nonstandard package with dimensions 7.60mm x 7.60mm x 4.35mm. The operating temperature range is -40°C to 125°C. This component is suitable for power supply filtering, DC-DC converters, and other applications requiring low profile and high current handling. The RoHS3 compliance is indicated but unverified. The part is also available under DigiKey part numbers 513-1550-2-ND, 513-1550-1-ND, and 513-1550-6-ND.
