Molded tantalum construction and ESR budget
The TPSA335K016R3500: This is a molded tantalum capacitor from the KYOCERA AVX TPS series, rated 3.3 µF at 16 V with ±10% tolerance. The 1206 (3216 Metric) footprint is a standard decoupling size; the 1.80 mm seated height fits 2 mm board-to-board gaps.
Temperature grade and deployment fit
At 125°C ambient, the voltage derating guideline for tantalum capacitors recommends staying below 2/3 of rated voltage — 16 V rated means a 10.6 V working ceiling at the high end. The molded case provides mechanical stability under vibration typical of factory-floor or automotive environments.
