The TAJY335M050RNJ: The 50 V voltage rating on a 3.3 µF tantalum gives enough headroom to decouple a 24 V supply rail with margin for transients up to 40 V — the derating rule of thumb (50 % of rated voltage for solid tantalum) still leaves 25 V continuous, which covers 12 V and 24 V industrial buses. The 1.7 Ohm ESR at 100 kHz sets the ripple-current ceiling: at 85°C ambient, the cap can handle roughly 0.5 A RMS before self-heating shifts the leakage. For a switching regulator output, this ESR is typical for the 2917 case size — expect ~100 mV of ripple at 300 mA load.
No forced last-time-buy window. The 2917 (7343 Metric) molded case is a standard footprint shared with many TAJ and T491 series caps — if a shortage hits, a functionally equivalent part from Kemet or Vishay in the same case size and voltage rating can be cross-referenced without a board spin.
