Rated current is 100 mA continuous, with saturation current matching the rated current at 100 mA — meaning the inductance holds until the current approaches the rated limit, then drops off sharply. DC resistance is 4.55 Ohm max, which at 100 mA produces a 45.5 mW I²R loss — negligible in a power rail filter but worth budgeting in a low-impedance supply path where every millivolt of drop counts. The self-resonant frequency is 10 MHz, so the inductive impedance dominates up to that point; above 10 MHz the part behaves capacitively and stops filtering. No magnetic shield means the flux field extends beyond the component body. In a dense layout, adjacent traces or other inductors within a few millimetres can couple energy — keep a clearance of at least one part width (3.2 mm) to neighbouring magnetics or sensitive analog traces. The ferrite core material gives good temperature stability up to 105 °C, so the inductance shift across the -40 to +105 °C operating range stays within the ±10% tolerance band. ## 1210 footprint and tape-and-reel supply The base product number LQH32DN covers the family; the full suffix 101K23L encodes the 100 µH value, ±10% tolerance, and packaging variant.","metaTitle":"Murata LQH32DN101K23L 100 µH Unshielded Inductor, 100 mA","metaDescription":"Murata LQH32DN101K23L drum core wirewound inductor, 100 µH ±10%, 100 mA rated, 4.55 Ohm DCR, unshielded ferrite core, 1210 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Inductors & Chokes"],"specifications":{"Mfr":"Murata Electronics","Type":"Drum Core, Wirewound","Series":"LQH32","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Q @ Freq":"-","Shielding":"Unshielded","Tolerance":"±10%","Inductance":"100 µH","Mounting Type":"Surface Mount","Package / Case":"Nonstandard","Product Status":"Active","Material - Core":"Ferrite","lifecycle_stage":"unknown","Size / Dimension":"0.126\\\" L x 0.098\\\" W (3.20mm x 2.50mm)","Base Product Number":"LQH32DN","DC Resistance (DCR)":"4.55Ohm Max","Current Rating (Amps)":"100 mA","Height - Seated (Max)":"0.087\\\" (2.20mm)","Operating Temperature":"-40°C ~ 105°C","Supplier Device Package":"1210 (3225 Metric)","Frequency - Self Resonant":"10MHz","Current - Saturation (Isat)":"100mA","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/acdbc11902e40fafa7dafbdc018aa5fb.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH32DN101K23L","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH32DN101K23L when reusing this data.
