Ripple floor and temperature reach
The TPSB685K020R0600: At 600 mOhm ESR and 6.8 µF, this TPS-series molded tantalum handles ripple currents typical of a 20 V rail decoupling or a timing hold-up cap — the ESR is the thermal bottleneck, not the capacitance.
Active status — no LTB clock
This BOM line stays stable across multi-year production runs without an obsolescence spin.
Footprint and board fit
1411 (3528 Metric) case, also listed as 1210 — the 3.50 mm x 2.80 mm footprint and 2.10 mm seated height fit standard 1210 pads. Size code B. Surface-mount, supplied on tape and reel or cut tape.
