It belongs to the TAJ series from KYOCERA AVX, a general-purpose line that covers the bulk of board-level decoupling and filtering needs across consumer, industrial, and automotive temperature domains. The 25 Ohm ESR (equivalent series resistance) is a typical figure for a small-case tantalum at this capacitance and voltage. For a 1 µF part used as a local decoupling cap near a digital IC, that ESR is acceptable — the ripple current at the switching frequencies involved is low enough that self-heating stays under control. If you are filtering a higher-ripple rail, the ESR becomes a design constraint: the I²R power loss scales with ripple current, and the cap's own temperature rise adds to the ambient. That 125°C upper limit is the absolute maximum ambient the part is designed to see — at sustained 125°C the leakage current and failure rate increase, so derating the applied voltage to 50% of rated (5 V or less) is standard practice for long-life designs in hot environments. ## Active lifecycle — no EOL worry for this BOM line","metaTitle":"TAJS105K010RNJ KYOCERA AVX TAJ Series 1 µF 10 V Molded","metaDescription":"TAJS105K010RNJ: 1 µF ±10%, 10 V rated, 1206 SMD, -55°C to 125°C, 25 Ohm ESR.
