Bulk capacitance for 16 V rails — 100 µF in a D-case footprint
The TAJD107K016SNJ: This is a 100 µF, 16 V rated tantalum capacitor in the standard 2917 (7343 Metric) D-case package — the footprint matches the industry-wide D-size layout, so it drops onto existing pads without a board spin. The 600 mOhm ESR at 100 kHz sets the ripple current ceiling and self-heating; for a 16 V rail with 100 mV p-p ripple, the capacitor dissipates roughly 17 mW at 170 mA ripple — well within the thermal budget of the molded case. Tolerance is ±10%, which keeps the actual capacitance within 90–110 µF across the temperature range — tight enough for timing circuits and bulk decoupling where the exact value matters less than the minimum floor.
Temperature grade — military band, not just industrial
The molded construction (Type: Molded) handles the thermal cycling without the case cracking that can occur in conformal-coated chips; the epoxy encapsulation matches the CTE of the tantalum anode across the range.
No last-time-buy window to track, no successor to qualify. The TAJ series is a long-running molded tantalum line with broad distribution coverage; sourcing through independent channels is straightforward for both prototype reels and production volumes.
