22 µF, 16 V molded tantalum — footprint and thermal envelope
The TAJB226K016RNJ is a 22 µF, 16 V molded tantalum capacitor from the KYOCERA AVX TAJ series, housed in a 1411 (3528 Metric) / 1210 case with a seated height of 2.10 mm. Its ±10% tolerance and 2.3 Ohm ESR define the ripple current capability and filtering bandwidth — the ESR sets the self-heating under AC ripple, so derate the applied ripple current against the datasheet power-dissipation limit for the 1411 footprint.
Board-fit checklist for the 1411 case
The 3.50 mm x 2.80 mm footprint (1411 / 3528 Metric) with a 2.10 mm max seated height fits standard 1210 land patterns — confirm the pad geometry matches the manufacturer's recommended solder-land dimensions for reflow or wave soldering. The molded case is general-purpose, non-hermetic — conformal coating is recommended in humid or condensing environments to prevent silver-migration failures on the anode termination.
