2.2 µF, 20 V, 5.3 Ohm ESR — the three numbers that decide fit
The TAJA225M020RNJ: This is a molded tantalum capacitor from the TAJ series, rated 2.2 µF at 20 V with a 5.3 Ohm ESR in a 1206 (3216 Metric) case.
Active production — no lifecycle risk for new builds
Full military temperature range — deployment context
The 1206 case keeps the footprint small enough for dense PCB layouts while the molded construction resists moisture ingress better than uncoated chips.
