Rated for 125 mA continuous current with a maximum DC resistance of 3.1 Ohm, this part is sized for low-current power rail filtering, bias-T decoupling, and signal-path chokes where the DC bias current stays under 100 mA to keep resistive losses manageable. ## Self-resonant frequency and Q factor set the usable band The self-resonant frequency (SRF) is 13 MHz. Above this frequency the inductor behaves capacitively, so the part is effective for filtering and impedance matching in circuits operating up to a few MHz, such as low-frequency DC-DC converter output stages or audio-band noise suppression. A Q factor of 35 at 1 MHz indicates moderate energy storage efficiency at that test frequency. The Q peak typically occurs near the SRF, so the part offers its best selectivity in the 1–10 MHz range. ## Unshielded construction and PCB placement This is an unshielded inductor. The open ferrite core radiates a magnetic field that can couple into nearby traces or components. Keep sensitive analog or RF circuitry at least one part-width away, and avoid routing a high-current loop directly under the inductor on the opposite board layer. The nonstandard case designation means the pad layout should follow the manufacturer's recommended land pattern, not a generic 1210 resistor footprint, to ensure solder fillet formation on the terminations. Operating temperature range is -40°C to +85°C, covering commercial and most industrial environments. The inductance tolerance is ±5%, which is tight enough for tuned LC filters where the capacitance tolerance is also held to 5% or better.","metaTitle":"Murata LQH32MN270J23L 27 µH Unshielded Wirewound Inductor","metaDescription":"Murata LQH32MN270J23L, 27 µH ±5% unshielded wirewound inductor. 125 mA rated current, 3.1 Ohm DCR, 13 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)","Ratings":"-","Q @ Freq":"35 @ 1MHz","Shielding":"Unshielded","Tolerance":"±5%","Inductance":"27 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)":"3.1Ohm Max","Current Rating (Amps)":"125 mA","Height - Seated (Max)":"0.087\\\" (2.20mm)","Operating Temperature":"-40°C~85°C","Supplier Device Package":"1210","Frequency - Self Resonant":"13MHz","Current - Saturation (Isat)":"-","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1221","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/cfd82089124c69e5e21a12ea773111de.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the LQH32MN270J23L's listed type and series?","answer":"The type is Drum Core, Wirewound and the series is LQH32.
