The capacitance and voltage rating place it as a bulk decoupling cap on a 3.3 V or 1.8 V supply rail — the 6.3 V rating gives 1.9× derating on 3.3 V, which is the standard practice for tantalum to avoid surge failures. The 900 mOhm ESR limits the ripple current it can absorb; for a 100 kHz buck converter output, the ripple current through the cap should stay under the manufacturer's ripple current rating, which is not listed here but can be estimated from the ESR and the power dissipation limit of the B case. ## Military temp range — fits avionics and downhole gear This cap can sit on a satellite payload board that sees -55 °C on the dark side and +125 °C near a thruster, or in a downhole tool that bakes at 125 °C. The molded case and the B-size footprint (3.50 mm × 2.80 mm, 2.10 mm seated height) fit standard pick-and-place and reflow profiles. The TAJ series is a long-running molded tantalum line with broad distribution coverage.","metaTitle":"TAJB686K006RNJ KYOCERA AVX 68 µF Molded Tantalum Capacitor","metaDescription":"TAJB686K006RNJ active production, 68 µF ±10%, 6.3 V, 900 mOhm ESR, -55 to +125 °C.
