Automotive-grade molded tantalum for under-hood decoupling
The TAJA105K025TNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 1 µF with ±10% tolerance and a 25 V voltage rating. The 1206 (3216 Metric) surface-mount package with a seated height of 1.80 mm fits standard PCB footprints for automotive ECUs and sensor modules. The molded construction provides mechanical robustness against vibration and thermal cycling.
ESR and lifetime at temperature
With an ESR of 8 ohms at 100 kHz, this capacitor is best suited for general-purpose decoupling and filtering rather than high-ripple-current power stages. The 2000-hour lifetime at 125°C defines the thermal endurance window: in a 105°C ambient, the expected life extends significantly per the Arrhenius acceleration model.
