68 µF D-case tantalum for decoupling and hold-up
The TAJD686K006RNJ: This is a 68 µF, 6.3 V rated molded tantalum capacitor in the 2917 (7343 Metric) D-case — a common footprint for bulk decoupling on power rails below 5 V, and for hold-up capacitance in circuits that ride through brief supply dips. The ±10% tolerance keeps the capacitance window tight enough for most filtering and energy-storage roles without over-specifying. Part of the TAJ series, it is a general-purpose molded style — no low-ESR or automotive grade, but suitable for a wide range of commercial and industrial boards where the 125 °C ceiling provides margin above standard 85 °C caps.
Temperature range and board fit
The D-case measures 7.30 mm x 4.30 mm with a seated height of 3.10 mm — confirm the board keep-out zone and the clearance under a neighbouring component before laying out the land pattern.
