68 µF at 10 V — molded tantalum for automotive decoupling
The TAJB686K010TNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, delivering 68 µF capacitance at 10 V with ±10% tolerance — a common value for bulk decoupling on 5 V and 3.3 V rails in automotive modules. Its 1.4 Ohm ESR at 100 kHz defines the ripple current capability: at 125°C ambient, the 2000-hour lifetime rating means the part is specified for continuous operation in engine-bay or transmission-control environments where the board sees sustained high temperature.
AEC-Q200 — the automotive gate
Package and footprint — 1411 (3528 Metric)
Housed in the industry-standard B case size (1411 / 3528 Metric), measuring 3.50 mm x 2.80 mm with a seated height of 2.10 mm max. The surface-mount footprint is shared across multiple tantalum suppliers, so a layout designed for this part can accept equivalents without a board spin.
