Product details

Molded tantalum for wide-temperature decoupling

Its 1.3 Ohm ESR at 100 kHz sets the ripple current handling and the self-heating limit — for a given ripple current, the internal temperature rise is I² × ESR, so a 500 mA ripple adds about 0.33 W of dissipation inside the package. The molded epoxy case provides mechanical stability across thermal cycling without the moisture sensitivity of uncoated chips.

Surface-mount footprint and board fit

Housed in a 2312 (6032 Metric) case with manufacturer size code W, the part measures 6.00 mm × 3.20 mm with a seated height of 1.50 mm max. The low profile suits tight board-stacking constraints — a 1.5 mm clearance above the component is enough for most conformal-coat or potting processes. Supplied on tape and reel, the part is pick-and-place ready for reflow soldering. The molded body is compatible with standard lead-free profiles; no special bake-out is required for this package type before assembly.

Frequently asked questions

What is the closest pin-compatible alternative to TAJW686K010YNJ?

Within the TAJ series, any molded tantalum in the same 2312 (6032 Metric) case with size code W is footprint-compatible. The key parametric differences to check are capacitance, voltage rating, and ESR — the TAJW686K010YNJ is 68 µF / 10 V / 1.3 Ohm. A higher-voltage or lower-ESR sibling will have a different dielectric thickness or anode construction, so confirm the application's derating requirements before substituting.
