The TAJB685K010RNJ is a molded tantalum capacitor from the TAJ series, rated 6.8 µF at 10 V with ±10% tolerance.
Manufacturer size code B, case dimensions 3.50 mm x 2.80 mm (0.138" x 0.110"), seated height 2.10 mm max. The 1411 (3528 Metric) footprint is shared across the TAJ B-case family — a single pad pattern serves multiple capacitance values if the BOM needs flexibility.
The equivalent series resistance is 3 Ohm. This ESR value is specified at 25°C and 100 kHz; it increases at lower temperatures and higher frequencies, so derate ripple current for the actual operating point.
The part is listed as RoHS compliant and lead-free per the manufacturer's specification. No additional compliance documentation is held on file; the datasheet confirms the RoHS status.
