Its 250 mOhm ESR is moderate for a 47 µF tantalum — high enough to limit ripple current but low enough to provide useful filtering on a 3.3 V or 1.8 V rail where bulk capacitance is needed to absorb load transients from a nearby switching regulator or digital load.
Full military temperature range — avionics and downhole ready
In an avionics power supply that sees -40°C cold-soak on the tarmac and +105°C near a hot engine bay, the capacitance and ESR remain within spec — no derating curve surprise at the cold end, and the 125°C ceiling provides margin above a typical 85°C ambient.
The B case (1411 / 1210 metric) measures 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. This is a common tantalum case size; the pad geometry matches the standard B-case land pattern used across many KYOCERA AVX and competitor parts.
