At 2.5 V it sits right at the supply rail for a 1.8 V or 2.5 V logic core — the voltage margin is tight but the 20 Ohm ESR means the ripple current handling is limited; don't expect this part to swallow high-frequency switching noise the way a ceramic would. It is surface-mount in the 0805 (2012 Metric) case, size code R. That means it can sit in an avionics black box, a downhole sensor module, or a satellite power bus where the ambient swings from cold-soak to hot-side — and the molded construction keeps the dielectric stable across that span. The TAJ series is a general-purpose line, not a high-reliability screened part, but the temp rating tells you the capacitor's materials are chosen for that envelope. Lifecycle status is Active. That means the manufacturer is still running this order code, no EOL notice has been issued, and new designs can use it without worrying about an imminent last-time-buy window.","metaTitle":"TAJR475K002RNJ KYOCERA AVX 4.7 µF Molded Tantalum Capacitor","metaDescription":"TAJR475K002RNJ — KYOCERA AVX TAJ series molded tantalum capacitor, 4.7 µF ±10%, 2.5 V, 20 Ohm ESR, -55°C to 125°C, 0805 package.
