Capacitance: 2.2uF Voltage rating: 25V ESR: 7 ohms Case size: 1206 Temperature range: -55°C to +125°C How to Choose the Right Tantalum Capacitor

When choosing a tantalum capacitor, there are a few key factors to consider:

Capacitance: The capacitance is the amount of charge that the capacitor can store. It is measured in farads (F). Voltage rating: The voltage rating is the maximum voltage that the capacitor can withstand without being damaged. It is measured in volts (V). ESR: The ESR is the equivalent series resistance of the capacitor. It is a measure of the internal resistance of the capacitor. A lower ESR means that the capacitor can deliver more current. Case size: The case size is the physical size of the capacitor. It is important to choose a capacitor that will fit in the available space. Conclusion

The T491A225K025AT is a high-performance tantalum capacitor from Kemet. It is ideal for use in a wide range of applications, where space is limited and high performance is required.
