Active production — AEC-Q200 qualified for automotive power rails
The Coilcraft LPS6235-824MRC is an active-production shielded drum core inductor in the LPS6235 series, qualified to AEC-Q200. Rated 820 µH at 260 mA with a saturation current floor of 160 mA, the part provides a 100 mA margin between rated and saturation limits — a useful headroom for transient loads in a 12 V automotive bus filter where the inductor sees ripple current on top of the DC bias.
820 µH at 260 mA — what the DC resistance and self-resonant frequency mean for the filter design
The 2.7 Ω maximum DCR sets the copper loss at 182 mW at full rated current — a figure that drives the temperature rise inside the 2424 (6.20 mm × 6.20 mm) footprint. For a 12 V-to-3.3 V buck converter switching at 100 kHz, the 2.5 MHz self-resonant frequency leaves over a decade of margin above the switching fundamental, so the inductor behaves as a pure inductive element in the filter passband. The ferrite core and full magnetic shield contain the flux within the package — adjacent components on a dense PCB see minimal coupling, which simplifies the layout of parallel power rails in a multi-output supply.

Strip packaging is the listed delivery form — suitable for hand assembly or low-volume reflow. For high-volume tape-and-reel requirements, confirm the packaging code with the distributor at RFQ time.
