D-case 6.8 µF at 50 V — the bulk-decoupling cross
The TPSD685K050R0200: The 200 mOhm ESR at 100 kHz sets the ripple-current ceiling: a lower ESR lets more AC ripple pass without self-heating, but 200 mOhm is typical for a D-case MnO2 part at this capacitance and voltage — adequate for general-purpose filtering, not a low-ESR grade for high-ripple POL converters. Operating temperature spans -55°C to 125°C, covering industrial and some automotive under-hood zones, though no AEC-Q200 qualification is listed on this entry.

D-case footprint and board-fit
The case code D is standard across the TPS series; the pad layout is shared with other D-case tantalums, so a single land pattern serves multiple capacitance values in the same voltage family. ±10% tolerance on the 6.8 µF nominal — the capacitance spread at 25°C is 6.12 µF to 7.48 µF. Derating the applied voltage to 80 % of the 50 V rating (40 V max) is standard practice for MnO2 tantalums to reduce the risk of field failure under surge conditions. Supplied on Tape & Reel or Cut Tape — the reel quantity is the standard 500 or 1000 depending on the distributor's packaging split. The molded body is compatible with reflow soldering; MSL rating is typically 3 for this series (168-hour floor life), though the specific MSL is not listed on this entry.
