The TAJD336K035KNJ is a molded tantalum capacitor from the TAJ series, rated 33 µF at 35 V with ±10% tolerance and 900 mOhm ESR. The 35 V rating gives headroom on a 12 V or 24 V rail — the derating rule of thumb (50% for solid tantalums) still leaves 17.5 V working voltage, which covers most industrial and automotive rails. The 900 mOhm ESR is moderate: it limits ripple current to about 400 mA RMS at 85 °C before self-heating becomes a concern, so this part suits bulk hold-up or output filtering on a linear regulator, not a high-ripple switching supply.
Full military temp range — -55 to 125 °C
The operating temperature range spans -55 to 125 °C, which is the military-temperature band. This capacitor can sit on a board inside an engine-bay ECU, a satellite power bus, or a downhole tool that sees 125 °C ambient. The 125 °C rating applies with derated voltage — at the top end, the 35 V rating drops to roughly 2/3 of the nominal value per the standard tantalum derating curve.
2917 case — footprint and stack-up fit
The 2917 (7343 Metric) case measures 7.30 x 4.30 mm with a seated height of 3.10 mm. This is a standard tantalum footprint that matches the industry-wide D case code. The 3.10 mm height clears most board-to-board spacing in a 1.6 mm PCB stack-up with a 10 mm mezzanine connector. The molded body is polarity-marked with a stripe on the anode side — orientation is clear under magnification or with a good light, so a field swap is straightforward if you have the right footprint on the board.
