47 µF at 20 V — D-case bulk decoupling
With 47 µF capacitance and a 20 V rating, it fits bulk decoupling on a 12 V or 5 V rail where the voltage margin stays above 20% derating — typical for industrial power supplies, motor drives, or telecom line cards. The 900 mOhm ESR is typical for a standard tantalum in this case size; it limits ripple-current handling to around 0.8–1 A at 100 kHz, so this part is not a fit for high-ripple output stages without a parallel ceramic bypass.
-55 to 125 °C — military temp range
The ±20% tolerance is loose enough that a 47 µF part at the low end measures 37.6 µF — factor this into the minimum capacitance required for hold-up time or regulator stability at cold start.
