0.22 µF, 50 V, 13 Ohm ESR — what it buys you
The TAJS224K050RNJ: 0.22 µF at 50 V with a 13 Ohm ESR — this is a standard-value tantalum for decoupling, RC timing, or filtering where you need stable capacitance over temperature and voltage bias. This cap sits comfortably in avionics, downhole instrumentation, or outdoor telecom enclosures where the ambient swings wide. No derating needed on the temperature spec itself.
1206 case — rework and layout fit
1206 (3216 Metric) footprint, 3.20 mm x 1.60 mm, seated height 1.20 mm max. The 1206 size is large enough to hand-solder or hot-air rework without a microscope — the pads are visible and the part stays put during reflow. Low profile fits under a 1.5 mm board-to-board gap. The S code (manufacturer size code) matches the 1206 body.
Active — no last-time-buy pressure
No need to scramble for a last-time-buy or qualify a substitute.
