That DCR at full load drops about 127 mV and dissipates roughly 82 mW — negligible in most power rails but worth budgeting if the inductor sits in a low-voltage output path where every millivolt of headroom matters. The unshielded construction means the magnetic field radiates into the surrounding board area. Keep sensitive analog traces, high-impedance nodes, or adjacent inductors at least one part-width away to avoid coupling. For a tightly packed DC-DC converter layout, a shielded part from the same LQH32 family would be the better call. ## Self-resonant ceiling and temperature envelope The self-resonant frequency of 43 MHz sets the practical upper limit for filtering or energy storage. Above that frequency the impedance turns capacitive, so this part suits switching converters switching in the hundreds-of-kHz to low-MHz range, not RF or high-speed signal paths. The ferrite core material maintains inductance within the ±20% tolerance band across that range. ## Active production — sourcing posture The 1210 (3225 metric) footprint and tape-and-reel packaging mean it drops into existing pick-and-place setups without a board respin. The base product number LQH32CN covers the full inductance range in this drum-core series, so a BOM change to a different value within the family keeps the same land pattern.","metaTitle":"Murata LQH32CN4R7M53L 4.7 µH Drum Core Inductor, 650 mA","metaDescription":"Murata LQH32CN4R7M53L 4.7 µH ±20% unshielded wirewound inductor, 650 mA rated current, 195 mOhm DCR, 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) Cut Tape (CT)","Ratings":"-","Q @ Freq":"-","Shielding":"Unshielded","Tolerance":"±20%","Inductance":"4.7 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":"LQH32CN","DC Resistance (DCR)":"195mOhm Max","Current Rating (Amps)":"650 mA","Height - Seated (Max)":"0.067\\\" (1.70mm)","Operating Temperature":"-40°C ~ 85°C","Supplier Device Package":"1210 (3225 Metric)","Frequency - Self Resonant":"43MHz","Current - Saturation (Isat)":"-","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4631e89acc724af2b252dede1df988c2.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the LQH32CN4R7M53L used for?","answer":"This 4.7 µH inductor is used for DC-DC converter output filtering, power supply noise decoupling, and energy storage in circuits drawing up to 650 mA.
