The 0805 (2012 Metric) case size is common for compact decoupling on power rails and signal filtering in space-constrained boards. At 125°C the voltage derating curve applies — typically 50% of rated voltage for tantalum capacitors above 85°C, so the effective working voltage at 125°C is 3.15 V. ## 7 Ohm ESR — ripple current and thermal budget ESR is specified at 7 Ohm. For a 4.7 µF capacitor at 100 kHz, this ESR translates to a dissipation factor around 6% and limits the ripple current to roughly 200 mA RMS before self-heating becomes significant. In a low-ripple decoupling role (e.g., bypassing a digital IC's Vdd pin) the 7 Ohm ESR is adequate; for high-ripple bulk filtering a lower-ESR tantalum or ceramic is preferred. The product status is Active.","metaTitle":"TAJR475K006RNJ KYOCERA AVX Molded Tantalum Capacitor 4.7 µF","metaDescription":"TAJR475K006RNJ from KYOCERA AVX, TAJ series, 4.7 µF ±10%, 6.3 V, 0805, -55°C to 125°C, 7 Ohm ESR.

The capacitance, voltage, tolerance, and case size are identical. Confirm the reel/tape specification from the manufacturer's packaging data to ensure the reel format matches your pick-and-place setup."},{"question":"Does TAJR475K006RNJ have polarity?","answer":"Yes, this is a molded tantalum capacitor — it is polarized. The positive terminal is marked with a stripe on the body. Reversing the voltage will damage the capacitor and may cause a short circuit.
