The DR1040-3R8-R is a shielded wirewound drum core inductor from Eaton - Electronics Division. It offers an inductance of 3.8 µH with a tolerance of ±30% and a rated current of 5.5 A, while the saturation current reaches 6.4 A. The low DC resistance of 13 mOhm max minimizes power losses, making it suitable for high-efficiency power conversion circuits.
The inductor features a ferrite core and is fully shielded to reduce electromagnetic interference. It is constructed in a surface-mount package with dimensions of 10.50 mm x 10.30 mm x 4.00 mm, and operates over a wide temperature range of -40°C to 125°C, enabling use in harsh environments.
Typical applications include DC-DC converters, power supplies, and voltage regulation modules where high current capability and low profile are required. The shielded design helps meet EMI compliance in compact electronic designs.
