220 µF bulk decoupling with a 1.2 Ω ESR floor
The TAJC227K004RNJ: At 220 µF and 4 V, this TAJ-series tantalum is a workhorse for rail smoothing and hold-up capacitance on low-voltage digital and analog supplies.
Military temperature grade — board environment fit
That means it stays within spec in an avionics LRU that sees -40°C cold-soak on the tarmac and 105°C internal ambient under full load. The molded case (2312 / 6032 Metric) is a standard footprint — the rework station profile for this package is well documented, and the part is polarity-sensitive, so double-check orientation before reflow.
Lifecycle status is Active.
