TAJD226K020H KYOCERA AVX Molded Tantalum Capacitor 22 µF 20

This TAJD226K020H is a 22 µF, 20 V molded tantalum capacitor from the KYOCERA AVX TAJ series, in the D case size (2917 / 7343 Metric). The ±10% tolerance is the standard production band for this series; if your circuit's bulk decoupling or hold-up cap needs tighter than 10%, you will need to screen or select a different tolerance grade. The 900 mOhm ESR at 25°C is the ceiling for ripple current handling — at 100 kHz the capacitor's self-heating is roughly I² × 0.9 Ω. For a 500 mA ripple current, that is 225 mW of internal dissipation; the part's thermal rise stays within the 125°C limit only if the board copper and airflow keep the ambient below about 105°C.
