For a 20 V rail with 100 mV pk-pk ripple, the ripple current through this capacitor is roughly 56 mA RMS — well within the typical derated limit for a B case at 125°C, but a layout engineer should verify the thermal impedance of the board's copper pour under the capacitor.","metaTitle":"TAJB226K020ANJ – KYOCERA AVX Molded 22 µF Tantalum Capacitor","metaDescription":"Active KYOCERA AVX TAJB226K020ANJ tantalum capacitor: 22 µF, 20 V, ±10%, B case, 1.8 ohm ESR, -55°C to 125°C, 2000 h life.
