Parametric fit for the BOM line
The TAJS106K006RNJ: The 4 Ω ESR (Equivalent Series Resistance) is the key loss parameter at the ripple frequency — for a 10 µF part in a 1206 case, this ESR figure sets the self-heating under AC ripple and the output ripple voltage in a buck converter's output filter.
Board-level integration and footprint
Surface-mount assembly with Tape & Reel packaging is standard for the 1206 footprint — the cut-tape option suits prototype or low-volume builds without reel commitment.
The part is classified as General Purpose within the TAJ series — no automotive (AEC-Q200) or high-reliability screening is implied, so it is suited for commercial and industrial applications where the standard tantalum derating guidelines are followed.
