The 0805 (2012 Metric) package keeps the footprint small — 2.05 mm × 1.30 mm — fitting tight PCB layouts where every square millimetre counts. ## Temperature range and lifetime — where it fits Lifetime is rated 2000 hours at 125°C — at 85°C ambient the expected life extends significantly per the Arrhenius acceleration model, but this is not a continuous high-temp automotive or engine-bay part. ## ESR and frequency — what 25 Ohm at 100 kHz means ESR is specified at 25 Ohm typical at 100 kHz — a moderate value for a 0.1 µF tantalum. For ripple current handling, the buyer should compare this against the ripple current in the circuit; a higher ESR means more self-heating at the same ripple current.","metaTitle":"TAJR104K020HNJ KYOCERA AVX TAJ Series 0.1 µF 20 V ±10%","metaDescription":"TAJR104K020HNJ from KYOCERA AVX: 0.1 µF, 20 V, ±10%, 0805, -55°C to 125°C, 2000 hrs @ 125°C.
