What are the key features of T491A105M035AT?
- 1 µF capacitance at 35 V rated voltage in a compact A-case (EIA 3216-18) molded tantalum SMD package
- MnO2 solid electrolyte construction delivers low ESR and stable capacitance over temperature and frequency
- Molded case with RoHS-compliant terminations enables reliable automated reflow assembly in high-density PCBs
What is T491A105M035AT used for?
The T491A105M035AT is used for decoupling and bypass capacitance on 5 V to 28 V power rails in telecommunications equipment, industrial control systems, and automotive electronics modules. Its 1 µF MnO2 tantalum construction ensures stable capacitance under voltage and temperature stress compared to ceramic alternatives. The A-case SMD form factor suits space-constrained board designs where bulk decoupling is required close to ICs.

Frequently Asked Questions
What is the capacitance, voltage rating, and package size of the Kemet T491A105M035AT?
The T491A105M035AT is a 1 µF tantalum capacitor rated at 35 V in an A-case (EIA 3216-18) SMD molded package, suitable for decoupling applications on power rails up to 35 V in compact PCB assemblies.
How does the MnO2 electrolyte in the T491A105M035AT compare to polymer tantalum for ESR performance?
The T491A105M035AT uses a manganese dioxide (MnO2) solid electrolyte, which provides moderate ESR levels suitable for general decoupling. Polymer tantalum capacitors offer lower ESR, but the MnO2 construction in this 1 µF 35 V part provides a cost-effective solution with long-proven reliability for bypass applications.
In which supply rail decoupling scenarios is the T491A105M035AT preferred over a ceramic capacitor?
The T491A105M035AT tantalum is preferred over MLCCs on 12 V to 35 V rails where ceramic capacitors lose significant capacitance due to DC bias derating. Its 1 µF rating is stable across the operating voltage range, maintaining effective bypass without the capacitance drop seen in X5R or X7R ceramics at high DC bias.
