The TAJA336M004RNJ delivers 33 µF capacitance at 4 V rated voltage in a molded 1206 case — a common footprint for low-voltage bulk decoupling on 3.3 V or 1.8 V supply rails. The 3 Ω ESR at 100 kHz sets the ripple-current handling and the self-heating under AC load; for a typical 100 mV ripple at 100 kHz, the dissipation stays under 3.3 mW, well within the part's thermal budget.
The TAJA336M004RNJ is a molded tantalum capacitor from the TAJ series, which KYOCERA AVX manufactures RoHS-compliant as standard. No separate RoHS certificate is needed for this ordering code — it ships under the standard lead-free termination finish.
Within the TAJ series, the closest parametric match is any other 33 µF, 4 V, ±20% molded tantalum in a 1206 case with the same A size code. The ESR value (3 Ω) is the key differentiator — a lower-ESR sibling (e.g., the TAJA336M004R) would have a different suffix. Confirm the ESR requirement before substituting.
Yes — like all tantalum electrolytic capacitors, the TAJA336M004RNJ is polarized. The positive terminal is marked with a stripe on the molded body. Reversing the voltage will damage the part and may cause catastrophic failure. The 4 V rating is the maximum DC voltage across the terminals, not the peak AC.
