The TPSD336K035T0200V: The 35 V rating provides 1.46× derating on a 24 V nominal rail — enough margin to survive load-dump transients without the capacitor entering avalanche. For an ECU or BMS board, that certification is the gate for PPAP submission. The 200 mOhm ESR at 100 kHz limits self-heating under ripple current — at 1 A ripple the internal temperature rise is about 0.2°C above ambient, well within the 125°C ceiling. This ESR also sets the output filtering corner frequency when used as a post-regulator bulk cap.
The rated lifetime is 2000 hours at 125°C with full rated voltage applied. In a 105°C under-hood environment, the acceleration factor per the 10°C halving rule extends useful life to roughly 8000 hours — about one year of continuous operation. For intermittent duty (ignition-on cycles), the calendar life stretches further. The molded construction keeps the anode and cathode connections stable across this swing — no potting voids to trap moisture.
Package and footprint — D case (2917) for standard pick-and-place
The D-size footprint matches the industry-standard tantalum land pattern for this capacitance-voltage combination — no pad geometry change from the previous generation. Surface-mount package compatible with standard reflow profiles (260°C peak, J-STD-020). The molded body is MSL 1 — no moisture sensitivity bake required before assembly, which simplifies the kitting workflow for an EMS line. The reel quantity follows the standard EIA-481 embossed carrier for 2917 case size.
