Rated for 900 mA continuous current with a saturation current floor of 1.1 A — the margin above the rated current means the inductance holds up under transient loads without collapsing into the resistive regime. Maximum DC resistance is 200 mOhm, which sets the copper-loss budget for the supply rail. ## AEC-Q200 and 125 °C operating ceiling AEC-Q200 qualification certifies the inductor for automotive stress profiles — temperature cycling, mechanical shock, and bias humidity at Grade 1 levels. The ferrite core and shielded construction contain the magnetic flux, reducing radiated EMI into nearby sensitive traces — a common requirement in automotive ECU layouts and compact DC-DC converter modules. ## Self-resonant frequency and test conditions Self-resonant frequency is 40 MHz — well above typical switching frequencies for point-of-load converters (2-5 MHz), so the inductor behaves as a pure inductive element in the passband. Inductance is measured at 100 kHz, the standard test frequency for power inductors in this value range. Tolerance is ±20%, which is typical for shielded power inductors — the saturation current floor is the tighter constraint for design margin, not the inductance tolerance itself.","metaTitle":"Coilcraft LPS4018-103MRC 10 µH Shielded Power Inductor","metaDescription":"Active Coilcraft LPS4018-103MRC, 10 µH shielded drum core inductor, 900 mA rated, 1.1 A saturation, 200 mOhm DCR, AEC-Q200 qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Inductors & Chokes"],"specifications":{"Mfr":"Coilcraft","Type":"Drum Core","Series":"LPS4018","Package":"Strip","Ratings":"AEC-Q200","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":"0.154\\\" L x 0.154\\\" W (3.90mm x 3.90mm)","DC Resistance (DCR)":"200mOhm Max","Current Rating (Amps)":"900 mA","Height - Seated (Max)":"0.071\\\" (1.80mm)","Operating Temperature":"-40°C~125°C","Supplier Device Package":"-","Frequency - Self Resonant":"40MHz","Current - Saturation (Isat)":"1.1A","Inductance Frequency - Test":"100 kHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0a1383b82e9440ac5710704b6c85e4ee.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LPS4018-103MRC/alternatives.json"},"ai":{"faq":[{"question":"How do I get current pricing and availability for LPS4018-103MRC?","answer":"Pricing and stock are confirmed at quote time.
