2.2 µF, 10 V, 12 Ω ESR — TAJ series molded tantalum
The TAJS225M010RNJ is a molded tantalum capacitor from the TAJ series, rated at 2.2 µF with ±20 % tolerance and 10 V DC working voltage. The 1206 (3216 Metric) case is one of the most widely used SMT footprints, making this cap a drop-in for many board layouts that already accommodate a 1206 tantalum. The S case code (manufacturer size code S) corresponds to the 1206 body dimensions: 3.20 mm × 1.60 mm × 1.20 mm seated height.
-55 to 125 °C — full military temperature range
No derating is required across this range for DC voltage — the 10 V rating holds at 125 °C.
