Its self-resonant frequency of 4.5 MHz means this inductor stays inductive well into the low-MHz switching range, making it a fit for DC-DC converter output filters and EMI suppression on power rails where the ripple frequency sits below 2–3 MHz. The base product number LQH43NH covers the full inductance range in this series; the suffix 221J03L encodes the 220 µH value, ±5% tolerance, and packaging variant.","metaTitle":"Murata LQH43NH221J03L 220 µH Inductor, 100 mA, AEC-Q200","metaDescription":"Murata LQH43NH221J03L wirewound drum core inductor, 220 µH, 100 mA, 4.56 Ohm DCR, AEC-Q200 qualified.

At 100 mA rated current, this produces about 45.6 mW of self-heating — negligible for the 1812 body, but the voltage drop across the winding (0.456 V at full current) must be accounted for in the power rail budget."},{"question":"What compliance documentation does Murata provide for LQH43NH221J03L?","answer":"As an AEC-Q200 qualified component, Murata provides a PPAP (Production Part Approval Process) package, RoHS/REACH compliance declarations, and a full reliability test report upon request through the supply chain."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH43NH221J03L","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH43NH221J03L when reusing this data.
