PM43-5R6M-RC Equivalent & Substitute Parts

Part Overview

The PM43-5R6M-RC is a 5.6 µH unshielded drum core wirewound inductor manufactured by Bourns Inc., rated for 1.6 A continuous current with a maximum DC resistance of 100 mOhm. This component is designed for surface mount applications in circuits requiring fixed inductance values with moderate current handling capability. The part maintains Active product status and is ROHS3 compliant, making it suitable for modern electronic assemblies. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility needs.
