Rated for 620 mA continuous current with a saturation floor of 660 mA (Isat), this part suits low-to-mid current DC-DC converter output filters and power-supply rail smoothing where the inductor sees the full load current. ## What the current and DCR ratings mean for your rail The 620 mA current rating is the thermal limit at 105°C ambient — the inductor can carry this current continuously without exceeding its maximum temperature. The 660 mA saturation current is the point where the inductance drops by 30% typically; above this the filter loses its attenuation and the ripple current rises sharply. With a self-resonant frequency of 15 MHz, this inductor behaves as an inductor up to roughly 5-7 MHz in a typical buck converter — above that the parasitic capacitance dominates and the impedance turns capacitive. For a 1-2 MHz switching regulator, the 15 µH value and 15 MHz SRF leave enough margin. The 1 MHz test frequency for the inductance value matches the typical switching frequency of many point-of-load converters — the 15 µH figure is representative of the inductance the circuit sees at the operating frequency. ## Active production and sourcing posture The tape-and-reel packaging supports automated reel feeding.","metaTitle":"Murata LQH3NPN150MMEL Shielded Power Inductor, 15 µH, 620 mA","metaDescription":"Murata LQH3NPN150MMEL drum core wirewound inductor, 15 µH ±20%, 620 mA rated, 348 mOhm DCR, shielded ferrite core in 1212 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":"LQH3","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"15 µH","Mounting Type":"Surface Mount","Package / Case":"1212 (3030 Metric)","Product Status":"Active","Material - Core":"Ferrite","lifecycle_stage":"unknown","Size / Dimension":"0.118\\\" L x 0.118\\\" W (3.00mm x 3.00mm)","Base Product Number":"LQH3NPN","DC Resistance (DCR)":"348mOhm Max","Current Rating (Amps)":"620 mA","Height - Seated (Max)":"0.059\\\" (1.50mm)","Operating Temperature":"-40°C ~ 105°C","Supplier Device Package":"1212 (3030 Metric)","Frequency - Self Resonant":"15MHz","Current - Saturation (Isat)":"660mA","Inductance Frequency - Test":"1 MHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3800","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/90c5f07bb626cfbc98c5fc54fd9965f6.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the inductance tolerance of LQH3NPN150MMEL?","answer":"The inductance tolerance is ±20%, which is typical for power-grade ferrite-core inductors used in DC-DC converter output filters where the closed-loop control compensates for the inductance variation."},{"question":"What is the closest alternative to LQH3NPN150MMEL in the LQH3 family?","answer":"Within the LQH3 series, the closest functional alternative would be a different inductance value at the same package size — for example, the 10 µH variant (LQH3NPN100MMEL) or the 22 µH variant (LQH3NPN220MMEL).
