The 0805 case keeps it small — 2.05 mm x 1.30 mm footprint — so it fits tight PCB layouts where a ceramic cap's DC bias derating would eat the effective capacitance. The 13 Ohm ESR is higher than a multilayer ceramic of the same value; that means more self-heating under ripple current, so it is better suited for bulk decoupling or timing circuits than for high-frequency bypass on a switching regulator output. Rated -55°C to 125°C — full military-temperature span. That puts it in avionics, downhole instrumentation, satellite payloads, or outdoor telecom cabinets where the ambient swings wide. No derating worry at the cold end; at 125°C the leakage current rises, but the cap is specified to operate there. ## Lifecycle and how to source Active product status from KYOCERA AVX — no EOL notice, no NRND flag. The TAJ series is a long-running molded tantalum line, so this order code is safe for new designs and repeat BOM positions.","metaTitle":"TAJR684K025RNJ – 0.68 µF 25 V Molded Tantalum Cap, 0805","metaDescription":"KYOCERA AVX TAJR684K025RNJ molded tantalum capacitor, 0.68 µF ±10%, 25 V, 0805 case, -55 to 125°C, 13 Ohm ESR.
