The 230 mA saturation current (Isat) is the hard ceiling: the inductance holds its value up to this current, then the ferrite core saturates and the inductance drops sharply. The 160 mA DC rating already includes a derating margin below saturation, so the practical operating limit is the DC rating, not the saturation number. ## AEC-Q200 qualification and the 105°C ceiling The ferrite core material and shielded construction keep the magnetic field contained within the 0806 package — important when the inductor sits next to a sensitive ADC reference or a CAN transceiver on the same board layer. ## Self-resonant frequency — where the part stops being an inductor The self-resonant frequency (SRF) is 7 MHz. Below this frequency the component behaves as an inductor with the rated 68 µH; at and above 7 MHz the parasitic winding capacitance dominates and the impedance becomes capacitive. For a buck converter switching at 2 MHz, the SRF gives plenty of headroom — the inductor's impedance stays inductive at the switching fundamental and its first few harmonics. The low profile keeps it under a 1.0 mm clearance on a two-layer board.","metaTitle":"Murata LQH2MPZ680MGRL 68 µH Shielded Power Inductor, 160 mA","metaDescription":"Murata LQH2MPZ680MGRL 68 µH shielded wirewound inductor, 160 mA rated, 8.04 Ohm DCR, AEC-Q200 qualified.

At the rated 160 mA DC current, the I²R loss is about 0.21 W — negligible for the 0806 package's power dissipation capability, but the DCR contributes to the output voltage drop in a filter application. For a 5 V rail drawing 100 mA, the DCR drop is 0.8 V, so the post-inductor voltage is 4.2 V — factor this into the regulator's feedback sense point."},{"question":"What is the tolerance and how is inductance tested?","answer":"The inductance tolerance is ±20%, tested at 1 MHz. A 68 µH part can measure anywhere from 54.4 µH to 81.6 µH at the test frequency. The 1 MHz test frequency is standard for power inductors in this value range — it avoids the SRF region (7 MHz) and gives a clean inductance reading."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH2MPZ680MGRL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH2MPZ680MGRL when reusing this data.
