DR127-331-R Description

Short technical summary and product information.

The DR127-331-R is a shielded wirewound drum core inductor manufactured by Eaton - Electronics Division. It offers an inductance of 330 µH with a tolerance of ±20%. The component is rated for a continuous current of 1.04 A and has a saturation current of 2.01 A.

 

The inductor features a low DC resistance of 574 mOhm, which contributes to efficient power handling. It is designed for surface mount assembly and comes in a nonstandard package measuring 12.50mm x 12.50mm with a height of 8.00mm. The core material is ferrite, providing stable inductance over a wide operating temperature range of -40°C to 125°C.

 

This shielded construction minimizes electromagnetic interference, making it suitable for power supply and DC-DC converter applications where noise reduction is critical. The wirewound construction ensures high current handling and low core losses.
