The 400 MHz self-resonant frequency means the inductor behaves as an inductor well above the switching frequency of most DC-DC converters (typically 500 kHz to 2 MHz), so the effective inductance at the switching fundamental is close to the 150 nH nominal value. Above SRF the impedance turns capacitive — a consideration if the rail carries high-frequency ripple beyond 400 MHz. ## 1210 footprint and board integration The unshielded drum core construction means magnetic flux radiates outside the body — keep sensitive traces or other magnetics at least one body width away to avoid coupling. The ferrite core material handles the 150 nH value with ±20% tolerance; the actual inductance at the test frequency of 1 MHz is the nominal value.","metaTitle":"Murata LQH32CNR15M33L Drum Core Inductor, 150 nH, 1.45 A","metaDescription":"Murata LQH32CNR15M33L wirewound drum core inductor, 150 nH ±20%, 1.45 A, 36.4 mOhm DCR, 400 MHz SRF, 1210 package.

Below this frequency the component behaves as an inductor; above it the impedance turns capacitive. For a DC-DC converter switching at 1-2 MHz, the inductor operates well below SRF, so the effective inductance is the nominal 150 nH."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH32CNR15M33L","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH32CNR15M33L when reusing this data.
