It belongs to the TAJ series, KYOCERA AVX's general-purpose manganese-dioxide tantalum line, and is specified for surface-mount assembly on tape-and-reel. At 1 µF and 35 V, this part fits decoupling applications on 24 V or 12 V rails where the margin to the 35 V rating covers transients without derating worry. The 6.5 Ω ESR at 100 kHz governs ripple current capability — higher ESR means the part self-heats more under AC ripple, so it suits low-ripple positions like output filtering on linear regulators or as a bulk cap after a moderate-switching DC-DC converter. ## Footprint and temperature envelope Molded construction means the epoxy case resists mechanical stress during reflow and handling better than conformal-coated parts, and the orientation mark (a stripe on the positive end) is visible under inspection — useful for the bench when hand-placing or reworking a board.","metaTitle":"KYOCERA AVX TAJB105K035K 1 µF 35 V Tantalum Capacitor","metaDescription":"KYOCERA AVX TAJ series molded tantalum capacitor, 1 µF ±10%, 35 V, B case 1210, 6.5 Ω ESR, -55 to +125 °C.
