An 18 µH value at 140 mA suits low-current DC-DC converter input/output filtering — think sensor rail smoothing or MCU local supply decoupling where the load stays under 100 mA continuous. The 5.2 Ohm max DCR means conduction loss at full rated current is about 102 mW — the inductor self-heats inside the 0806 footprint, so keep the trace copper pour under the part to help sink that heat. ## 0806 footprint and board-fit check Unshielded construction — magnetic flux couples into adjacent traces and components. In a mixed-signal layout, place the inductor at least 3–5 mm from sensitive analog or RF signal paths to avoid noise injection. Self-resonant frequency at 30 MHz — the inductor behaves as an inductor up to about 10–15 MHz; above that the parasitic capacitance dominates. For a 1–2 MHz switching converter the SRF is cleanly above the switching harmonics. ## Temp range and sourcing posture Operating temperature -40 °C to +85 °C covers industrial and commercial environments — outdoor telecom cabinets, factory-floor sensor nodes, and office power supplies all fall inside this band.","metaTitle":"Murata LQH2MCN180M52L 18 µH Unshielded Inductor, 0806","metaDescription":"Murata LQH2MCN180M52L drum core wirewound inductor, 18 µH, 140 mA, 5.2 Ohm DCR, 0806 package.

For a buck converter output filter the inductance tolerance shifts the crossover frequency; design the compensation with enough phase margin to cover the full tolerance band."},{"question":"Is LQH2MCN180M52L shielded or unshielded?","answer":"Unshielded — the drum core construction leaves the magnetic field exposed. In a dense layout with nearby traces carrying high-speed signals, the stray field can induce noise. Keep a 3–5 mm gap to sensitive analog or RF traces, or switch to a shielded variant if the board density forces overlap."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH2MCN180M52L","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH2MCN180M52L when reusing this data.
