Product details

Capacitance, voltage, and temperature range

The TAJA335K006RNJ: Rated 3.3 µF at 6.3 V with ±10% tolerance — this is a bulk decoupling cap for a 3.3 V or 5 V rail where the voltage derating rule (typically 80% of rated voltage) leaves 5.04 V headroom, well above any nominal rail.

ESR and ripple current reality

7 ohm ESR at 100 kHz — this is on the higher side for a tantalum cap of this size. In a switching-regulator output filter, the ripple voltage will be I_ripple × 7 Ω; keep the ripple current below ~50 mA to stay within the self-heating limit at 125°C.

1206 (3216 Metric) case, size code A, seated height 1.80 mm max. The 0.126" × 0.063" land pattern is standard; no via-in-pad needed for this two-terminal part. Surface-mount, molded construction — the epoxy case resists moisture better than uncoated ceramic, but the part is still polarized; the anode mark on the top indicates the positive terminal.

The TAJ series is widely second-sourced by Kemet and Vishay, but this specific order code is a direct cross to the AVX TAJ datasheet.

Frequently asked questions

Is TAJA335K006RNJ polarized?

Yes — it is a molded tantalum capacitor. The positive terminal is marked on the top of the case. Reversing the polarity will damage the part.

Can I replace TAJA335K006RNJ with a higher voltage capacitor?

A higher-voltage tantalum in the same 1206 case (e.g., 10 V or 16 V) will have a larger derating margin and similar ESR, but the capacitance value may shift. Confirm the replacement's capacitance and ESR match your circuit's ripple requirements.

Is TAJA335K006RNJ RoHS compliant?

The evidence does not explicitly list RoHS status, but KYOCERA AVX's TAJ series is generally RoHS-compliant. Confirm with the manufacturer's datasheet or a compliance certificate at order time.
