The TAJC337K006RNJ: This is a molded tantalum capacitor from the TAJ series, rated 330 µF at 6.3 V with ±10% tolerance. The 2312 (6032 Metric) case is a standard footprint — same as the common D-size tantalum, so it drops into existing PCB layouts without a pad change.
The molded case handles the thermal cycling without cracking — a common failure point on conformally-coated tantalums in harsh environments.
Lifecycle — active production, no EOL scramble
No last-time-buy window, no NRND flag. You can design this into a new BOM today and expect multi-year availability.
