15 µF, 10 V, 1206 — the board-fit reality
It comes in a 1206 (3216 metric) surface-mount package, measuring 3.20 mm x 1.60 mm with a seated height of 1.80 mm — a common footprint for decoupling and filtering on dense PCBs, but one that demands 0.50 mm clearance under low-profile enclosures.
Temperature range and lifetime — what 125°C means
For a 15 µF cap on a 10 V rail, this ESR is typical for the TAJ A-case size — it handles moderate ripple but won't support high-frequency switching regulators without parallel bypassing. The ESR also contributes to the voltage drop during transient loads; factor it into your output ripple budget.
