The 90 mA continuous current rating is the DC bias level at which self-heating from the 21.4 Ohm DCR starts to shift the inductance — stay below it to keep the filter corner frequency where you designed it. The 57 mA saturation current (Isat) is the hard ceiling: above this the ferrite core saturates and inductance collapses to a fraction of the nominal value, turning your LC filter into a wire. For a buck converter running at 100 kHz, the peak inductor current during a load transient must stay under this number or the output ripple doubles and the control loop loses phase margin. ## Package and board-fit — 2424 footprint The shielded ferrite drum core keeps the magnetic field contained, so adjacent traces carrying 24 VDC or a 100 kHz switching node see minimal eddy-current coupling — no extra keep-out zone beyond the standard 0.5 mm pad-to-pad clearance for the 2424 land pattern. The ±20% tolerance on the 6.8 mH value is typical for ferrite-core power inductors — the inductance drops about 10% from the nominal at 90 mA bias, so the actual filter cutoff shifts by roughly one-third of an octave over the load range. The self-resonant frequency of 800 kHz sets the upper bound for the switching frequency: above 400 kHz the parasitic winding capacitance starts to resonate with the inductance, and the impedance curve flattens.","metaTitle":"Coilcraft LPS6235-685MRC Shielded Power Inductor, 6.8 mH","metaDescription":"Coilcraft LPS6235-685MRC drum-core shielded inductor, 6.8 mH ±20%, 90 mA rated current, 57 mA saturation, AEC-Q200.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Inductors & Chokes"],"specifications":{"Mfr":"Coilcraft","Type":"Drum Core","Series":"LPS6235","Package":"Strip","Ratings":"AEC-Q200","Features":"-","Q @ Freq":"-","Shielding":"Shielded","Tolerance":"±20%","Inductance":"6.8 mH","Mounting Type":"Surface Mount","Package / Case":"2424 (6060 Metric)","Product Status":"Active","Material - Core":"Ferrite","lifecycle_stage":"unknown","Size / Dimension":"0.244\\\" L x 0.244\\\" W (6.20mm x 6.20mm)","DC Resistance (DCR)":"21.4Ohm Max","Current Rating (Amps)":"90 mA","Height - Seated (Max)":"0.138\\\" (3.50mm)","Operating Temperature":"-40°C~125°C","Supplier Device Package":"2424","Frequency - Self Resonant":"800kHz","Current - Saturation (Isat)":"57mA","Inductance Frequency - Test":"100 kHz"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5300","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/338f51cd4ddd180fcc59f5f9f9fae76d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the saturation current of the LPS6235-685MRC and why does it matter?","answer":"The saturation current (Isat) is 57 mA. Above this current the ferrite core saturates and the inductance drops sharply — the inductor no longer stores energy, and the ripple current in a buck converter rises uncontrolled.
