68 µF, 10 V, 1.3 Ohm ESR — the bulk decoupling decision
The TAJW686M010RNJ: This is a molded tantalum capacitor from the TAJ series, rated 68 µF at 10 V with ±20% tolerance and 1.3 Ohm ESR — the ESR figure determines how much AC ripple current the part can handle before self-heating becomes a derating issue.
You can design this into a new BOM or replenish an existing line without worrying about an imminent discontinuation.
Surface-mount 2312 case — footprint and handling
Package is 2312 (6032 Metric), size code W, measuring 6.00 mm x 3.20 mm with a seated height of 1.50 mm — this is a low-profile molded case that sits flush on the board, no lead standoff. The molded body is polarity-marked with a stripe on the positive end — orientation is obvious under magnification or a vision system, so a field swap is doable if you have the right soldering iron and a steady hand.
