The TAJB336K006RNJ: This is a 33 µF, 6.3 V rated tantalum capacitor in the TAJ series from KYOCERA AVX, molded case, ±10% tolerance. The 6.3 V rating means it fits 3.3 V, 2.5 V, and 1.8 V rails with healthy derating margin — a 50 % voltage derating rule-of-thumb leaves 3.15 V working voltage, which covers the common logic rails but not a 5 V supply.
Package footprint and board fit
Case code B (EIA 3528-21), measuring 3.50 mm x 2.80 mm with a seated height of 2.10 mm. The 1411 (3528 Metric) footprint is a standard tantalum land pattern — the same pad layout used across the TAJ B-size family, so a BOM swap between capacitance values within the same voltage code is a direct drop-in. Surface-mount assembly on standard FR-4; the molded case handles reflow profiles up to 260 °C peak per JEDEC. No special handling beyond standard MSL 3 bake precautions if the reel has been exposed.
