Frequently Asked Questions
What capacitance and voltage rating does the T491A225M010AT provide?
The T491A225M010AT offers a 2.2 µF capacitance with a 10 V voltage rating and ±20% tolerance. These specifications make it suitable for decoupling 3.3 V or 5 V power rails in compact digital and analog circuits.
Which PCB layout scenarios benefit from the molded SMD package of T491A225M010AT?
The molded SMD package of the T491A225M010AT is well-suited for high-density PCB layouts where space is limited. With a compact body, it fits on boards designed for portable electronics, wearable devices, and IoT nodes that require 10 V or lower operating voltages.
How does the MnO2 electrolyte in T491A225M010AT affect its reliability compared to wet tantalum capacitors?
The MnO2 (manganese dioxide) solid electrolyte in the T491A225M010AT provides a non-liquid construction that resists leakage and improves long-term reliability. Unlike wet tantalum capacitors, it can handle operating temperatures across a range of -55°C to +125°C without electrolyte evaporation concerns.
When would you choose T491A225M010AT over a ceramic capacitor with the same 2.2 µF value?
The T491A225M010AT is preferred over ceramic alternatives in applications requiring stable capacitance regardless of DC bias voltage. Ceramic capacitors rated at 2.2 µF can lose up to 80% of their capacitance at rated voltage, while the tantalum MnO2 design maintains consistent performance at 10 V.
