The 300 mOhm max DCR sets the DC copper loss at 192 mW at full rated current — budget this into the thermal design for the 5x5 mm footprint. Shielded construction contains the magnetic flux within the ferrite core, reducing radiated EMI into adjacent power-stage or signal traces on the same board layer. ## Current rating and saturation headroom for transient loads Rated 800 mA at 10 µH — the 1.2 A saturation current provides 50 % headroom above the DC rating, enough to handle load transients typical of a buck converter output stage without inductance collapse. The self-resonant frequency of 44 MHz means the inductor behaves as a pure inductive element up to roughly 10 MHz — above that, the winding capacitance resonates and the impedance turns capacitive. Inductance is tested at 100 kHz, the standard test frequency for power inductors in this value range; the actual inductance at the switching frequency of a 500 kHz to 2 MHz converter will be close to the 10 µH nominal. ## 5x5 mm footprint fits low-profile power supplies Surface-mount on a nonstandard pad layout — the datasheet footprint drawing should be followed for solder fillet and thermal relief; the ferrite core does not require a thermal pad beneath the part.","metaTitle":"Coilcraft LPS5015-103MRC 10 µH Shielded Power Inductor","metaDescription":"Coilcraft LPS5015-103MRC 10 µH shielded drum core inductor, 800 mA rated current, 1.2 A saturation, 300 mOhm DCR, 5x5 mm SMD.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Inductors & Chokes"],"specifications":{"Mfr":"Coilcraft","Type":"Drum Core","Series":"LPS5015","Package":"Strip","Ratings":"-","Features":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"10 µH","Mounting Type":"Surface Mount","Package / Case":"Nonstandard","Product Status":"Active","Material - Core":"Ferrite","lifecycle_stage":"unknown","Size / Dimension":"0.197\\\" L x 0.197\\\" W (5.00mm x 5.00mm)","DC Resistance (DCR)":"300mOhm Max","Current Rating (Amps)":"800 mA","Height - Seated (Max)":"0.059\\\" (1.50mm)","Operating Temperature":"-40°C~125°C","Supplier Device Package":"-","Frequency - Self Resonant":"44MHz","Current - Saturation (Isat)":"1.2A","Inductance Frequency - Test":"100 kHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0e72ddff79e6671b10ec1374708c6a39.pdf","sourceUrl":null},"ai":{"faq":[{"question":"How can I order the LPS5015-103MRC or check availability?","answer":"The LPS5015-103MRC is an active Coilcraft part sourced to order against your BOM quantity."},{"question":"What is the saturation current of the LPS5015-103MRC?","answer":"The saturation current (Isat) is 1.2 A.
