330 µF, 10 V, 900 mOhm ESR — bulk decoupling for automotive power rails
The TAJE337K010TNJV is a molded tantalum capacitor from the KYOCERA AVX TAJ series, offering 330 µF capacitance at 10 V with ±10% tolerance. Its 900 mOhm equivalent series resistance at 100 kHz is the figure that governs ripple current handling and self-heating in a filter or decoupling application — lower ESR means less temperature rise for the same AC ripple, which matters when the capacitor shares a tight PCB with other heat-sensitive components.
The wide temperature span also suits industrial outdoor equipment and avionics power supplies where the thermal cycle is severe.
2917 (7343 Metric) SMD — size code E
The 2917 (7343 Metric) case measures 7.30 mm x 4.30 mm with a seated height of 4.30 mm. The manufacturer size code E is a standard footprint for 330 µF tantalum capacitors at this voltage rating — the PCB land pattern is shared across multiple vendors, so a second-source swap is straightforward if the BOM ever needs it.
