4.7 µF at 25 V — B case, 1.5 Ohm ESR
The TAJB475M025A is a molded tantalum capacitor from the KYOCERA AVX TAJ series, delivering 4.7 µF capacitance with ±20% tolerance at a 25 V rated voltage.
Rated across the full -55 to 125 °C range, this cap fits avionics, satellite, downhole, and missile-guidance power rails where the ambient swings beyond industrial limits. The molded construction keeps the dielectric sealed against moisture ingress in unpressurised environments.

1411 / 1210 footprint — B case code
The B case measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm max, landing on standard 1411 (3528 Metric) and 1210 pads. The 0.083-inch height keeps it below low-profile PCB clearance limits in mezzanine stacks.
