3.3 µF at 25 V — fit check for the BOM line
TAJT335K025RNJ is a molded tantalum capacitor from the TAJ series, delivering 3.3 µF capacitance with ±10% tolerance at a 25 V rated voltage. With an ESR of 3.5 Ohm, this part is not optimized for high-ripple-current bulk decoupling; it is better suited for general-purpose filtering, coupling, or hold-up where the AC ripple component is small relative to the DC bias.
At 125°C the leakage current and derating factor must be checked against the datasheet curve, but the raw temperature rating alone clears the bar for most harsh-environment designs.
Housed in a 1411 (3528 Metric) / 1210 surface-mount case, size code T, with dimensions 3.50 mm x 2.80 mm and a seated height of 1.20 mm. This is a common tantalum footprint; the pad layout matches standard 1210 solder pads, so no board respin is needed if the BOM already calls for that land pattern.
