The 200 mA continuous current rating is the DC bias current at which the inductance typically drops by 10% — stay below this to keep the filtering or energy-storage characteristic within tolerance. Maximum DC resistance is 5.26 Ohm, which at 200 mA produces about 0.21 W of I²R loss — within the package's thermal budget for most PCB layouts, but worth checking against the ambient temperature derating if the inductor sits near other heat sources. Self-resonant frequency is 8 MHz; above that the component behaves capacitively, so the usable filtering range is below roughly 2–3 MHz for a typical buck converter or EMI filter application. ## Shielded construction and 1210 footprint Shielded ferrite core construction contains the magnetic field, reducing radiated EMI to adjacent traces and components — important when the inductor shares a dense board with sensitive analog or RF circuitry. Operating temperature range is -40°C to 85°C, covering most indoor and industrial ambient conditions but not extended automotive or under-hood environments.","metaTitle":"Murata LQH32PN121MN0L Inductor, 120 µH, 200 mA, Shielded","metaDescription":"Murata LQH32PN121MN0L drum core wirewound inductor, 120 µH ±20%, 200 mA, 5.26 Ohm DCR, shielded, -40°C to 85°C, 1210 footprint.","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)","Ratings":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"120 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":"LQH32PN","DC Resistance (DCR)":"5.26Ohm Max","Current Rating (Amps)":"200 mA","Height - Seated (Max)":"0.087\\\" (2.20mm)","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"1210","Frequency - Self Resonant":"8MHz","Current - Saturation (Isat)":"170mA","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1445","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/83f8d02b386a8d7a67b8f85a9df66d00.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current (Isat) for LQH32PN121MN0L?","answer":"The saturation current is 170 mA.
