4.7 µF, 16 V, 1206 — TAJ series molded tantalum
The TAJS475K016A: This is a surface-mount molded tantalum capacitor from the TAJ series, rated 4.7 µF at 16 V with ±10% tolerance. The 1206 case (3.20 mm × 1.60 mm footprint) is a common size for decoupling and filtering on dense PCBs where board area is tight. The 4.5 Ohm ESR (equivalent series resistance) is the figure to watch for ripple current capability — higher ESR means more self-heating under AC load, so derate the voltage or limit ripple current in high-frequency switching applications.
It fits avionics, downhole instrumentation, satellite payloads, and outdoor telecom gear where the ambient envelope swings from arctic cold to engine-bay heat.
The storeroom can stock it without worrying about a sudden EOL window.
