0.33 µF, 35 V, ±20% — molded tantalum in 1206
The TAJA334M035RNJ is a molded tantalum capacitor from the KYOCERA AVX TAJ series, rated at 0.33 µF with a 35 V working voltage and ±20% tolerance. It comes in a standard 1206 (3216 Metric) surface-mount package, size code A, measuring 3.20 mm x 1.60 mm with a seated height of 1.80 mm max. The 35 V rating gives solid margin on a 12 V or 24 V rail — typical derating practice for tantalum caps is 50% of rated voltage, so this part comfortably covers a 12 V bus with headroom for transients.
ESR and temperature range — the fit for harsh environments
ESR is specified at 15 Ohm at 100 kHz, which is the dominant loss term for this small-case tantalum.
