The TPSA226K006R0500 is a 22 µF molded tantalum capacitor rated at 6.3 V with a 500 mOhm ESR, housed in a standard 1206 (3216 Metric) case. It belongs to KYOCERA AVX's TPS series, a general-purpose line for surface-mount boards.
ESR and voltage — what they mean on the rail
500 mOhm ESR at 6.3 V is a typical value for a 1206 tantalum at this capacitance. In a 3.3 V digital rail, the ripple current capability is set by the I²R heating in the ESR — keep ripple below 500 mA RMS to stay within the 125 °C ceiling. The 6.3 V rating leaves about 1.9 V of headroom above a 3.3 V rail, which is adequate for most low-voltage supplies but not for 5 V rails — a 10 V or 16 V rated part would be needed there.
