Capacitance, voltage, and derating
The TAJB685K010H: 6.8 µF at 10 V with ±10% tolerance is a common decoupling value for 3.3 V and 5 V rails. Tantalum capacitors require voltage derating — a 10 V rated part on a 5 V rail provides a 50% safety margin, which keeps the failure rate low under ripple and surge conditions.
Housed in the 1411 (3528 Metric) / 1210 case size with a B code footprint — 3.50 mm x 2.80 mm, seated height 2.10 mm max.
