The TAJC226K010RNJ: This is a 22 µF tantalum capacitor rated at 10 V with a 1.8 Ohm ESR — the three numbers that define its job on a supply rail. It is a molded, surface-mount part in the TAJ series from KYOCERA AVX, with ±10 % tolerance and general-purpose features.
Temperature grade — -55 to 125 °C for avionics and downhole gear
It is a fit for avionics power supplies, satellite payload regulation, downhole instrumentation, and missile-guidance electronics where the ambient swings beyond the industrial -40 to 85 °C envelope.
Size code C — 2312 (6032 Metric) footprint
Manufacturer size code C, which maps to the case dimensions 6.00 mm × 3.20 mm (0.236" × 0.126") with a seated height of 2.80 mm max. The metric case code is 6032. This is the footprint you need for the PCB land pattern — confirm the pad geometry matches the KYOCERA AVX recommended layout before committing the board.
