The TAJB335M035YNJ is a 3.3 µF molded tantalum capacitor rated at 35 V, ±20% tolerance. This combination is common for bulk decoupling on 24 V or 12 V rails where the voltage derating rule of thumb (50% margin) still leaves headroom — 35 V derated to 17.5 V covers a 12 V rail with margin for transients.
The molded construction (type: Molded) provides mechanical stability across that range.
ESR and its impact on circuit performance
With a 3.5 Ohm ESR, this capacitor is suited for general-purpose filtering and decoupling where moderate ripple current is present. Higher ESR limits the capacitor's ability to handle AC ripple without self-heating — for low-ESR applications like switching regulator outputs, a different series would be needed.
