TAJA155K010RNJ – KYOCERA AVX TAJ Series 1.5 µF 10 V Molded

1.5 µF, 10 V, 10 Ohm ESR — the bulk decoupling fit for a 1206 pad

The TAJA155K010RNJ: This is a 1.5 µF molded tantalum capacitor from the TAJ series, rated at 10 V with a 10 Ohm ESR at 100 kHz. The 1206 case size (3.20 mm x 1.60 mm) fits the standard 1206 footprint on a PCB, so you can drop it into a decoupling or filter position without a layout change.

That means it can sit in an engine-bay ECU, a downhole sensor, or a satellite power rail without derating at the hot end. The 2000-hour endurance at 125 °C is the standard tantalum wear-out spec — budget it for the mission life.
