The TPSD226M025S0200 is a molded tantalum capacitor from KYOCERA AVX's TPS series, offering 22 µF capacitance with a 25 V rating in a 2917 (7343 Metric) surface-mount case. The 200 mOhm ESR is moderate for this capacitance value — adequate for general-purpose output filtering on a 12 V rail, but not intended for high-ripple switching regulator outputs where a lower-ESR polymer capacitor would be specified.
Package and temperature — 2917 footprint, wide thermal range
The 2917 (7343 Metric) case measures 7.30 mm x 4.30 mm with a seated height of 3.10 mm max — a standard tantalum footprint compatible with most reflow profiles. Tolerance is ±20%, typical for tantalum capacitors; the manufacturer size code is D.
