22 µF at 10 V — the BOM fit check
ESR is 600 mOhm. In a power-supply output filter or a DC-DC converter input, the ripple current through the ESR generates I²R heat — the cap will run warm if the ripple is significant.
Molded case, size code W — footprint and polarity
The molded case is 2312 (6032 Metric) — 6.00 mm x 3.20 mm footprint, 1.50 mm seated height. Size code W. The molded body has a clear polarity band on the positive end; on a board with tight clearance, the 1.50 mm height fits under a low-profile shield or a mezzanine board. The surface-mount pads are standard for the 2312 footprint — no special land pattern needed beyond the usual tantalum pad with a thermal-relief tie to the positive plane.
Product status is Active. That means KYOCERA AVX is still manufacturing this order code — no last-time-buy notice, no EOL clock running. For a BOM that needs a stable tantalum source, this part is a straightforward quote-to-order line through independent distribution.
