It delivers 470 nH inductance at 1 MHz test frequency with a ±30% tolerance, rated for 2.9 A continuous current. The shielding and ferrite core construction contain the magnetic flux, making this part suitable for DC-DC converter output filtering and power rail decoupling where radiated EMI must stay below board-level limits. ## Current rating and saturation headroom The 2.9 A continuous current rating is the thermal limit at 28.8 mOhm max DCR — at full rated current the I²R loss is roughly 242 mW, which the 1210 body dissipates without exceeding the 105°C upper temperature limit. The saturation current of 4.4 A provides 1.5 A of headroom above the continuous rating, so the inductance does not collapse during load transients or startup inrush. Self-resonant frequency is 100 MHz, well above the switching frequencies of common buck converters (500 kHz to 2 MHz), so the inductor behaves as a pure inductive element in the passband without parasitic capacitive coupling. ## Package footprint and reflow integration The nonstandard case designation means the pad layout follows the 1210 industry-standard land pattern — no special footprint beyond the standard 1210 solder pads is required. The ferrite core material maintains inductance stability across this range, though the ±30% tolerance means the actual inductance at temperature can shift — budget the tolerance into the feedback loop compensation.","metaTitle":"Murata LQH32PBR47NNCL Shielded Inductor, 470 nH, 2.9 A","metaDescription":"Murata LQH32PBR47NNCL drum core wirewound inductor, 470 nH ±30%, 2.9 A rated current, 28.8 mOhm DCR, shielded ferrite core in 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":"Shielded","Tolerance":"±30%","Inductance":"470 nH","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":"LQH32PB","DC Resistance (DCR)":"28.8mOhm Max","Current Rating (Amps)":"2.9 A","Height - Seated (Max)":"0.067\\\" (1.70mm)","Operating Temperature":"-40°C ~ 105°C","Supplier Device Package":"1210 (3225 Metric)","Frequency - Self Resonant":"100MHz","Current - Saturation (Isat)":"4.4A","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4510c968c4ccaaf38b0fbf633e33d94e.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current rating for LQH32PBR47NNCL?","answer":"The saturation current (Isat) is 4.4 A.
