Its 145 nH inductance at 1 MHz test frequency targets RF decoupling and impedance-matching roles where a small, surface-mount part with predictable self-resonance is needed. Rated for 700 mA continuous current with a maximum DC resistance of 79.3 mOhm, the part keeps conduction losses low enough for power-supply filtering and signal-line isolation in compact designs. The 60 Q factor at 100 MHz and a self-resonant frequency of 500 MHz mean it maintains inductive behaviour well into the UHF band — useful for RF front-end circuits and high-speed digital decoupling. ## Last Buy — what it means for your BOM Murata has flagged the LQH31HNR14K03L with a Last Buy status. This is the final window to secure production quantities before the part is discontinued. For a BOM that already uses this inductor, the Last Buy designation means ordering now — through independent distribution against an RFQ — is the only way to guarantee supply for ongoing builds. The 1206 footprint and 145 nH / 700 mA rating are common enough that a cross-search across the LQH31 family or other Murata wirewound series may yield a drop-in candidate, but no pin-compatible alternative is formally listed. ## 1206 SMD — hand-solderable and board-friendly This is a large enough footprint for hand-soldering with a fine-tipped iron — no hot-air station required — and the ferrite core is robust against typical reflow profiles. The unshielded construction means magnetic coupling to nearby traces is possible, so keep a ground plane under the part in dense layouts. The tape-and-reel packaging (also available as cut tape) suits both prototyping and production pick-and-place.","metaTitle":"Murata LQH31HNR14K03L Drum Core Inductor, 145 nH, 700 mA","metaDescription":"Murata LQH31HNR14K03L wirewound ferrite-core inductor, 145 nH ±10%, 700 mA, 79.3 mOhm DCR, 1206 SMD.
