The 35 V rating provides headroom on a 12 V rail and comfortably handles a 24 V bus. The D-case (2917 / 7343 metric) footprint is a standard size for power supply decoupling and output filtering in industrial and telecom equipment. ## ESR and temperature endurance ESR is 1.3 Ohm at 100 kHz — this sets the ripple current capability and self-heating. For a 6.8 µF part on a 100 kHz switching regulator output, the ESR dominates the impedance and limits the AC ripple the cap can absorb before internal temperature rise accelerates wear. The part is qualified for 2000 hours at 125°C, so in a 105°C ambient the expected life extends well beyond that.","metaTitle":"TAJD685M035HNJ Tantalum Capacitor – KYOCERA AVX TAJ Series","metaDescription":"KYOCERA AVX TAJD685M035HNJ molded tantalum capacitor: 6.8 µF, 35 V, ±20%, 1.3 Ohm ESR, -55°C to +125°C, D-case 2917.
