0805LS-111XJLC – COILCRAFT

Overview

The Coilcraft 0805LS-111XJLC is a high-performance, unshielded wirewound ferrite inductor designed for demanding RF applications. Its critical operational characteristic is the balance between a low DC resistance (DCR) of 50 mOhms and a substantial maximum DC current rating of 2 A, enabling efficient signal path management. A key design consideration for this series is managing parasitic capacitance at higher frequencies; while its self-resonant frequency (SRF) is a respectable 1.2 GHz, designers must carefully model its impact on circuit stability, especially when operating near this limit, to avoid unintended oscillations.
