The 50 V rating gives comfortable margin on a 24 V rail — the derating rule of thumb (50% of rated voltage for tantalum) still leaves 25 V headroom, which covers most industrial 24 V bus transients without pushing the dielectric into breakdown. The 8 Ohm ESR is the number that matters for ripple current: at 100 kHz, a 100 mA ripple current dissipates 80 mW of self-heat. In a dense PCB with limited airflow, that heat adds to the ambient and reduces the capacitor's life. ## Active lifecycle — no end-of-life pressure, but single-source risk If supply tightens, the alternative is a different manufacturer's 0.47 µF, 50 V, C-case tantalum with a different ESR and possibly different footprint details — a board requalification would be needed. ## Package and temperature — 2312 (6032 Metric) C-case, -55 to 125 °C Housed in the 2312 (6032 Metric) C-case package, measuring 6.00 mm x 3.20 mm with a seated height of 2.80 mm. The C-case is a common tantalum footprint — it fits the standard 2312 land pattern, so a board designed for a generic C-case tantalum will accept this part without layout changes.","metaTitle":"TAJC474M050RNJ KYOCERA AVX TAJ Series Molded Tantalum","metaDescription":"TAJC474M050RNJ — KYOCERA AVX TAJ series molded tantalum capacitor, 0.47 µF, 50 V, ±20%, 8 Ohm ESR, -55 to 125 °C.
