What this molded tantalum does on your board
The TAJT684M035RNJ: This is a 0.68 µF molded tantalum capacitor from the TAJ series, rated at 35 V with ±20% tolerance. The 1411 (3528 Metric) case, size code T, measures 3.50 x 2.80 mm with a seated height of 1.20 mm. This low profile fits tight board stacks in portable or sealed assemblies.
Surface-mount 1411 (3528 Metric) case, also listed as 1210. The 0.138 x 0.110 inch (3.50 x 2.80 mm) footprint matches standard tantalum land patterns. Reflow profile follows JEDEC J-STD-020 for MSL — no special bake needed if stored dry. The general-purpose designation means no special screening or low-ESR rating; it is the baseline option for bulk decoupling and RC timing.
