3B751

Fixed Inductors Overview

The Gowanda Electronics 3B751 is a fixed axial leaded inductor featuring an unshielded toroidal core construction. It provides a nominal inductance of 7.5 µH with a tolerance typically within standard industrial ranges. The component supports a maximum current rating of 3 A and exhibits a maximum DC resistance of 30 mΩ. Designed for through-hole mounting, this wirewound power choke utilizes ferrite core technology to deliver stable performance in high-current applications requiring reliable magnetic shielding characteristics.

Fixed Inductors Procurement Notes

Verify the specific datasheet version for exact tolerance and saturation current limits, as these parameters can vary by manufacturing batch. Confirm that the unshielded nature aligns with your EMI requirements. Ensure axial lead dimensions match your board layout constraints before finalizing procurement orders.

Fixed Inductors Selection Notes

Select the 3B751 when a 7.5 µH inductance value is required with a 3 A current handling capability. Consider the unshielded toroidal form factor for applications where space allows for larger components but cost-effectiveness is prioritized over compactness. Evaluate thermal management needs given the 30 mΩ resistance at full load.
