68 µF bulk cap in a standard D-case footprint
The TPSD686M016R0150 is a 68 µF, 16 V molded tantalum capacitor in the 2917 (7343 Metric) D-case — a widely used footprint for high-value tantalum caps on power rails and decoupling banks. Rated ESR is 150 mOhm, which sets the ripple-current ceiling and the self-heating under AC load — for a bulk cap on a 100 kHz buck output, the ripple current should be derated so the I²R loss stays within the case's thermal budget. The -55 to 125°C operating range covers industrial and automotive-adjacent environments without requiring a high-temp screening grade — the molded case handles the thermal cycling.
Active production — no LTB clock ticking
The TPS series is a general-purpose molded tantalum line, not a low-ESR or high-reliability variant, so the derating guidelines for surge voltage and ripple current follow the standard MIL-PRF-55365/4 curves for this case size.
Board-fit and layout considerations
Surface-mount assembly on a 2917 package: the molded body is compatible with reflow profiles up to 260°C peak per J-STD-020, but the part carries no MSL rating in the cited data — confirm bake requirements with the lot-specific certificate.
