Molded tantalum, 1206 footprint, 35 V rail fit
TAJA105K035KNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, in a 1206 (3216 Metric) surface-mount package. Rated 1 µF at 35 V with ±10% tolerance, it fits decoupling and filtering roles on a 24 V rail with healthy margin.
Lifetime and temperature grade
Rated for 2000 hours at 125°C, this part is suited for high-temperature environments such as engine bay electronics or industrial control modules where ambient temperatures regularly exceed 85°C.
ESR and ripple current handling
Equivalent series resistance is 7.5 Ohm at 100 kHz, which sets the ripple current capability and self-heating under AC load. For a 1 µF part at 35 V, this ESR is typical for the TAJ series in the A case code.
