TAJE687K002RNJ is a molded tantalum capacitor from the TAJ series, rated 680 µF at 2.5 V with ±10% tolerance. The 200 mOhm ESR keeps ripple heating manageable in a 2.5 V supply rail — a common voltage for DDR memory VDDQ or core logic.
Wide temperature range — avionics and downhole ready
In an engine-bay ECU or satellite power bus, the capacitance stays within spec across the thermal swing — no derating curve guesswork.
E-case 2917 — footprint and board fit
Manufacturer size code E, 7.30 mm x 4.30 mm footprint, 4.30 mm seated height. Surface-mount 2917 (7343 metric) package — the standard large-case tantalum for high-capacitance bulk storage on a 2.5 V rail.
