The 33 µH value at 115 mA means this part suits low-current filtering or energy storage where the DC bias stays well below the rated current — at 115 mA the inductance holds within tolerance; push beyond that and the ferrite core begins to saturate, dropping the effective inductance. ## Unshielded construction — plan the PCB layout accordingly This is an unshielded drum-core inductor, so the magnetic field radiates from the component. In a dense layout, keep sensitive traces or other magnetics at least a component width away to avoid coupled noise. The 1210 (3225 Metric) footprint is standard — the same pad pattern serves the wider LQH32 family, so a single PCB land pattern covers multiple inductance values. The self-resonant frequency is 12 MHz, meaning above that frequency the inductor behaves capacitively. For filtering applications, keep the operating frequency below 12 MHz — typically use it up to about 4-6 MHz where the impedance is still predominantly inductive. The Q factor is 40 at 1 MHz, which is moderate for a ferrite-core part at this inductance.","metaTitle":"Murata LQH32MN330J23L 33 µH Unshielded Inductor, 115 mA","metaDescription":"Murata LQH32MN330J23L drum core wirewound inductor, 33 µH ±5%, 115 mA rated current, 3.5 Ohm DCR, 12 MHz SRF, 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":"40 @ 1MHz","Shielding":"Unshielded","Tolerance":"±5%","Inductance":"33 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":"LQH32MN","DC Resistance (DCR)":"3.5Ohm Max","Current Rating (Amps)":"115 mA","Height - Seated (Max)":"0.087\\\" (2.20mm)","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"1210 (3225 Metric)","Frequency - Self Resonant":"12MHz","Current - Saturation (Isat)":"-","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1278","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cfd82089124c69e5e21a12ea773111de.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy LQH32MN330J23L and how is it quoted?","answer":"Submit an RFQ for a firm quote."},{"question":"What is the inductance tolerance and test frequency?","answer":"The inductance is 33 µH with ±5% tolerance, tested at 1 MHz.
