100 µF, 16 V, military temp — the bulk cap for a wide-range rail
The TAJD107K016H: This is a 100 µF, 16 V molded tantalum capacitor in the 2917 (7343 Metric) D-size case, good for bulk decoupling or energy storage on a rail that sees -55 to 125 °C — think avionics, downhole tools, or satellite power distribution where the ambient swings hard.
600 mOhm ESR — what it means for ripple and heat
600 mOhm ESR at 25 °C sets the ripple-current ceiling. At 100 kHz, the self-heating from a 1 A ripple current is about 0.6 W — that heat has to leave the 2917 case through the board copper, so the pad layout and adjacent components matter more than the capacitor itself. Tantalum capacitors have a voltage derating rule of thumb: stay at or below 50 % of rated voltage for reliable operation. At 16 V rated, that means keep the DC bias under 8 V to avoid field-failure risk from surge current.
Active production — no EOL clock ticking
Listed as Active with no announced end-of-life. That means it's still a design-in candidate, not a last-time-buy scavenger hunt.
