Frequently Asked Questions
What are the capacitance, voltage rating, and tolerance specifications of the T491B226K010AT?
The T491B226K010AT is a 22 µF tantalum capacitor rated at 10 V with 10% capacitance tolerance. It uses MnO2 solid electrolyte in a molded SMD case B package, providing reliable decoupling performance in compact low-voltage power supply designs.
How does the MnO2 electrolyte in the T491B226K010AT improve reliability compared to wet tantalum capacitors?
MnO2 solid electrolyte eliminates the risk of electrolyte leakage and offers lower ESR than wet tantalum capacitors. For the T491B226K010AT's 22 µF, 10 V rating, this means stable operation across temperatures without the failure modes associated with liquid electrolytes in high-vibration or high-temperature environments.
For which power supply filtering scenarios is the T491B226K010AT a strong fit compared to ceramic capacitors?
The 22 µF, 10 V T491B226K010AT excels in bulk decoupling where ceramic capacitors of equivalent value would suffer voltage coefficient derating. Tantalum capacitors maintain their 22 µF capacitance more consistently under DC bias, making them preferred for low-dropout regulator output filtering and power rail stabilization at 3.3 V and 5 V levels.
