Rated for 910 mA continuous current with a saturation floor of 850 mA — the usable DC load sits just below the point where inductance starts to roll off, so a converter pulling 800 mA has roughly 50 mA of margin before the core saturates. ## DC Resistance and Copper Loss Budget Maximum DC resistance is 168 mOhm — at the full 910 mA rating, the I²R copper loss reaches about 139 mW, which is the dominant heat source inside the 1212 body. The 27 MHz self-resonant frequency means the inductor behaves as an inductor well into the low-MHz switching range; above that the parasitic capacitance dominates and the impedance turns capacitive. ## Footprint and Board Integration The shielded construction reduces magnetic coupling to adjacent traces and components, which matters when the inductor sits near a sensitive analog front-end or a high-impedance feedback node.","metaTitle":"Murata LQH3NPN4R7MGRL 4.7 µH Shielded Inductor, 910 mA","metaDescription":"Murata LQH3NPN4R7MGRL 4.7 µH ±20% shielded wirewound inductor, 910 mA rated, 168 mOhm DCR, 27 MHz SRF, 1212 footprint.

A DC-DC converter drawing peak current above this threshold will see the inductor lose stored energy, increasing ripple and potentially hitting the switch current limit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH3NPN4R7MGRL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH3NPN4R7MGRL when reusing this data.
