Capacitance, voltage, and ESR — the three numbers that size the BOM
This TAJC156M025RNJ is a 15 µF tantalum capacitor rated at 25 V with ±20% tolerance and a 1.6 Ohm ESR — the three values that determine whether it fits your rail decoupling or filtering node. For a 12 V rail derated to 50%, the 25 V rating gives a comfortable margin against voltage spikes.
This makes the part suitable for avionics, satellite, downhole instrumentation, and engine-bay electronics where ambient temperature extremes are routine.
