It carries a rated current of 540 mA and a saturation current of 570 mA, with a maximum DC resistance of 480 mOhm — the DCR figure sets the I²R conduction loss in the power path and governs the temperature rise at full load. The ferrite core and shielded construction contain the magnetic flux within the 3.00 mm × 3.00 mm × 1.50 mm 1212 (3030 Metric) package, reducing radiated EMI into adjacent traces or sensitive analog circuits on the same board layer. ## AEC-Q200 qualification and temperature envelope The self-resonant frequency of 10 MHz means the inductor behaves as an inductor well above the switching fundamental of most automotive DC-DC converters (typically 400 kHz to 2.2 MHz), so the effective inductance at the switching frequency stays close to the 22 µH nominal value. ## Sourcing and procurement The LQH3NPZ220MMEL is sourced through authorized and independent distribution channels. Pricing and lead time are confirmed at RFQ against the BOM quantity.","metaTitle":"Murata LQH3NPZ220MMEL 22 µH Shielded Inductor, AEC-Q200","metaDescription":"AEC-Q200 qualified 22 µH shielded wirewound inductor, 540 mA rated, 570 mA saturation, 480 mOhm DCR.

This 5.6 % headroom means the inductance holds within tolerance at the rated load; exceeding Isat causes the inductance to roll off as the core saturates, which increases ripple current in a buck converter and raises the output voltage ripple."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH3NPZ220MMEL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH3NPZ220MMEL when reusing this data.
