The TAJB106M006RNJ is a molded tantalum capacitor from the TAJ series, rated at 10 µF with ±20% tolerance and a 6.3 V voltage rating. The 3 Ohm ESR (Equivalent Series Resistance) is the spec that governs ripple current handling and self-heating in decoupling or filtering applications — a higher ESR means the capacitor runs warmer for the same AC current, so derate the ripple current below the calculated maximum if the ambient is above 85°C. This is a standard industrial/military temperature grade, not a commercial-grade part.

Package and footprint checklist
Surface-mount molded case, size code B, measuring 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. The 1411 (3528 Metric) footprint is shared with standard tantalum B-case parts — verify the pad geometry on your PCB matches the manufacturer's recommended land pattern, especially the cathode-end termination width, to avoid tombstoning during reflow.
