The 2000 hours at 125°C rating means the capacitor is qualified for continuous operation at that temperature, not just survival — relevant for engine-bay or downhole electronics where ambient exceeds 105°C. The 2917 (7343 Metric) case size (7.30 mm x 4.30 mm, 3.10 mm seated height) is a standard footprint for bulk tantalum capacitors; the D-size code matches common PCB land patterns for 680 µF parts.","metaTitle":"TAJD687M004SNJ KYOCERA AVX TAJ Series Molded Tantalum","metaDescription":"TAJD687M004SNJ molded tantalum capacitor, 680 µF at 4 V, 500 mOhm ESR, -55°C to 125°C, 2000 hrs at 125°C.
