The ±10% tolerance and 8 Ohm ESR are typical for a B-case (1411 / 3528 Metric) part at this capacitance and voltage. The 50 V rating gives you a 20% derating margin on a 40 V rail, which is the standard practice for tantalum reliability in power-supply filtering.
The ESR at the cold end will rise, but the 8 Ohm spec is at room temperature — budget the ESR shift if the application sees -55°C.
The B-case size is 3.50 mm x 2.80 mm (0.138" x 0.110") with a seated height of 2.10 mm (0.083"). The pad layout follows the standard 1411 (3528 Metric) or 1210 footprint — confirm the land pattern from the TAJ series application note for the recommended solder-paste aperture.
