Overview of the T491D226K020AT7683

The T491D226K020AT7683, also known simply as the T491 series, is a type of tantalum capacitor, which is widely used in both industrial and consumer electronics. It is a type of electrolytic capacitor, which consists of a tantalum metal anode, an electrolyte, and a layer of dielectric material deposited on the anode. The important features of the T491 series include:

• Operating temperature range of -55°C to +85°C
• Rated voltage range of 4V to 120V
• Capacitance range of 0.22µF to 4.7µF

Applications of the T491D226K020AT7683

The versatile nature of the T491 series means it has a wide range of potential applications. It is typically used as a filter in circuits that require DC-biasing, such as in power supplies and audio components. The T491 series can also be used in digital circuits to reduce noise and protect circuitry from voltage spikes. In addition, the capacitor is often used in high-frequency circuits as a type of frequency-selective element, due to its low series inductance.

The T491 series can also be used in RF circuits, as its temperature coefficient of capacitance (TCC) is very stable. This makes it especially suitable for use in areas where temperature variations are common, such as outdoors or in automotive applications. In addition, the T491 series is used in military-grade projects, due to its rugged construction, which makes it highly resistant to shock and vibration.

Working Principle of the T491D226K020AT7683

Tantalum capacitors are part of the family of electrolytic capacitors, which include aluminum and ceramic capacitors. As with all electrolytic capacitors, the T491 series is polarized, which means that it must be connected correctly to the circuit in order for it to work correctly. Connecting the capacitor incorrectly could damage it, or even cause it to fail completely.

The working principle of the T491 series is based on the electronic properties of tantalum metal. When a voltage is applied across the terminals of the capacitor, an electric field is created and the dielectric material is polarized. This continues until the electric field reaches a level where the movement of charge carriers is restricted, thus forming an ideal capacitor. As a result, the capacitor is able to store and release electrical energy as needed.

In addition, the device has a low Equivalent Series Resistance (ESR) and is able to work reliably in temperatures ranging from -55°C to +85°C. This makes the T491 series ideal for use in harsh conditions.

Conclusion

The T491D226K020AT7683 is a versatile tantalum capacitor that offers excellent performance in a wide range of situations. It is well suited to applications that require DC-biasing or involve RF signals, and it has a high level of durability and reliability. Thanks to its properties and features, this component can be used in a variety of different applications, making it an ideal choice for industrial, consumer and military-grade projects.
