In a buck converter that peaks at 2 A during startup or transient, the inductance will drop below 2.2 µH, increasing ripple current. The 76.8 mΩ DCR at 1.85 A dissipates about 260 mW; in a 1210 footprint without forced airflow, that heat must conduct through the PCB copper to stay within the 85°C ambient ceiling. ## Shielding and self-resonant frequency Shielded construction contains the magnetic field, so the inductor can sit adjacent to other magnetics or a sensitive analog trace without coupling noise. The 70 MHz self-resonant frequency is well above the switching frequency of most DC-DC converters (typically 500 kHz to 2 MHz), so the inductor behaves as a pure inductance in-band. ## Package and footprint — 1210 (3225 metric) The ferrite core and wirewound construction mean the part is not magnetically shielded by a metal cap — the ferrite drum itself provides the shielding, so the PCB copper pour under the part should be solid to avoid eddy-current losses.","metaTitle":"Murata LQH32PN2R2NNCL Shielded Wirewound Inductor, 2.2 µH","metaDescription":"Murata LQH32PN2R2NNCL drum core wirewound inductor, 2.2 µH ±30%, shielded, 1.85 A rated current, 76.8 mΩ DCR, 1210 (3225 metric) 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":"Shielded","Tolerance":"±30%","Inductance":"2.2 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)":"76.8mOhm Max","Current Rating (Amps)":"1.85 A","Height - Seated (Max)":"0.087\\\" (2.20mm)","Operating Temperature":"-40°C~85°C","Supplier Device Package":"1210 (3225 Metric)","Frequency - Self Resonant":"70MHz","Current - Saturation (Isat)":"2A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What is the inductance and current rating of LQH32PN2R2NNCL?","answer":"The inductor is 2.2 µH ±30%, rated for 1.85 A continuous current with a saturation current of 2 A."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/LQH32PN2R2NNCL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/LQH32PN2R2NNCL when reusing this data.
