For existing designs, this means the BOM line remains stable through normal procurement cycles; for new designs, the part is available for qualification without a looming obsolescence risk. ## ESR and temperature — the bench reality In a power-supply decoupling role, this ESR will cause voltage ripple at the load and heat the part under AC current.","metaTitle":"TAJR105K025RNJV KYOCERA AVX TAJ Series Molded Tantalum","metaDescription":"TAJR105K025RNJV from KYOCERA AVX is an active TAJ series molded tantalum capacitor: 1 µF ±10%, 25 V, 8 Ohm ESR, 0805 package, -55 to 125°C.
