The TAJD156K025H: At 15 µF and 25 V rated, this part fits bulk decoupling on a 12 V or 5 V rail with derating margin — the 25 V rating leaves headroom above a 12 V rail even with a 20 % transient overshoot. The ±10 % tolerance is the standard production band for this series — the actual capacitance at 25 V bias will measure near 15 µF, not at the upper or lower limit, for most reels. If the circuit requires tighter tolerance, a different series or a screening step would be needed.
2917 case, molded body — board-fit checklist
The 2917 (7343 Metric) case measures 7.30 mm x 4.30 mm with a seated height of 3.10 mm max. The molded construction gives a consistent outline and flat top for pick-and-place nozzle pickup. Surface-mount assembly on a standard FR-4 board with reflow soldering is the intended process.
