T491A475K016ZT Capacitors

Tantalum Capacitors

Tantalum capacitors refer to electronic components that utilize the dielectric properties of Ta2O5 in order to store and release an electrical charge. These capacitors are typically made of tantalum metal, an oxide layer, and two metallic electrodes, known as anode and cathode. Commonly, they are used to store an electric charge in a circuit, so when the power is cut off, the charge remains in the circuit.

The T491A475K016ZT is one of the most popular types of tantalum capacitor. This type of device is designed to provide a high input impedance, low leakage, and low equivalent series resistance (ESR). It is primarily used for bypass capacitor applications, providing a reliable decoupling of signal lines, power supply lines, and data lines exposure to noise. Moreover, with a frequency range of 0.5-600 MHz, it is capable of being used in high frequency switching applications up to 200V.

Working Principle: The working principle of a T491A475K016ZT tantalum capacitor is based on the concept of electron traps, which is when an electric field, generated by a capacitor’s electrodes, serves to trap and store electrons. When a voltage is applied across the device, it increases the density of the charge trapping electrons in the dielectric layer, resulting in an increase of the electric field strength. As this process continues, more and more charge is stored within the dielectric barrier, thus increasing the capacitance of the device.

Application Field: For its high input impedance, low leakage, and wide range of operating frequencies, the T491A475K016ZT is widely used in electronic applications such as energy storage systems, controller circuit control, power supply unit standby, and medical device applications. These capacitors are also used as bypass capacitors in a variety of high frequency circuits as they can help reduce noise and improve signal integrity.

When choosing a tantalum capacitor, it is important to make sure that the device is suitable for the particular application. While the T491A475K016ZT is a popular capacitor, it is important to check that the specific parameters match the requirements of the application. Moreover, while tantalum capacitors are generally reliable and stable, it is also important to ensure that they are properly rated for the given application in order to prevent any unnecessary damage.
