The TAJD475K035HNJ: This is a KYOCERA AVX TAJ series molded tantalum capacitor, 4.7 µF with ±10% tolerance, rated at 35 V. The D-case (2917 / 7343 Metric) footprint is a common land pattern — 7.30 mm x 4.30 mm, seated height 3.10 mm max. That matches the standard 2917 pad layout on most PWB libraries; no footprint tweak needed if the BOM already calls a D-case tantalum.
Temperature endurance and operating envelope
That 125°C rating is the absolute case temperature — in a 85°C ambient with self-heating from ripple current, the internal temperature rise eats into the 2000-hour budget. For a power-supply output filter running near full rated voltage at 105°C ambient, expect accelerated aging; derate voltage or reduce ripple current to stretch service life.
