22 µF, 25 V, 100 mOhm — bulk decoupling fit
22 µF at 25 V rated voltage gives 1.5× derating margin on a 12 V rail and over 4× on a 5 V rail — the typical tantalum derating rule of thumb (50-80% of rated voltage) is satisfied without extra headroom. The 100 mOhm ESR is low for a D-case tantalum; it keeps ripple current handling around 1.2 A at 100 kHz, which covers most point-of-load decoupling and output filtering in DC-DC converters.
This capacitor can sit in an avionics power supply, a downhole sensor module, or a satellite payload without a temperature-grade gap. The molded construction provides mechanical stability across the range, with no conformal-coat compatibility issues.
2917 (7343 Metric) case, size code D. The 7.30 mm × 4.30 mm footprint and 3.10 mm seated height match the standard D-case land pattern per the KYOCERA AVX TPS series application note.
