Molded tantalum, 4.7 µF at 20 V — TAJ series fit note
The TAJC475K020YNJ: This is a molded tantalum capacitor from the TAJ series, rated 4.7 µF at 20 V with ±10% tolerance. The molded case provides mechanical stability and consistent footprint for automated pick-and-place assembly. Case code C (2312 / 6032 Metric) measures 6.00 mm x 3.20 mm with a seated height of 2.80 mm max — a common footprint for decoupling and bulk storage on mixed-signal boards.
The molded construction handles thermal cycling without cracking the dielectric — a known failure mode in uncoated tantalum parts.
