10 µF, 16 V, 2 Ohm ESR — the bulk decoupling fit
The TAJC106K016SNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 10 µF with a 16 V working voltage and ±10% tolerance. The 2 Ohm ESR sets the ripple current ceiling — for a 100 kHz buck converter output, the capacitor's self-heating stays within limits if the RMS ripple current is kept under 400 mA.
Case C 2312 — footprint and board layout
Housed in the industry-standard 2312 (6032 Metric) case size with a seated height of 2.60 mm max, this capacitor's footprint matches the EIA 6032-28 land pattern. The molded construction provides consistent dimensional control for pick-and-place assembly.
