T491C155M035ZTZB01 is a type of capacitor which belongs to the Tantalum Capacitors family. It\'s a type of electrolytic capacitor that is made of tantalum and has a capacitance ratings of 15 uF, a tolerance of 10%, a maximum operating temperature of 85 degrees C and a voltage rating of 35V. It is also known as a wet tantalum capacitor because it uses an electrolyte, usually aqueous, to create its electrical field. The main advantage of Tantalum capacitors is their ability to provide high capacitance ratings in a very small form factor.

The main application of the T491C155M035ZTZB01 is as an effective by-pass capacitor for a switching power supply, where it can help reduce transient responses. In this type of application, the capacitor helps regulate the current flow through the circuit by quickly absorbing and discharging the extra power when needed. This helps prevent any sudden changes or overloads, thereby allowing for a smooth, efficient operation. It can also be used as a DC blocking capacitor in audio equipment, as it prevents DC signals from being passed along the audio signal path.

The working principle of the T491C155M035ZTZB01 is based on the electrical double layer capacitance (EDLC) effect. This is a phenomenon in which two layers are formed inside the Tantalum dielectric material when a voltage is applied. The two layers act as oppositely charged surfaces, which, when put together, generate an electrical field capable of storing energy. The higher the voltage, the larger the electrical field and thus, the greater the capacitance.

The T491C155M035ZTZB01 has a very low ESR rating and high maximum ripple current, making it an ideal choice for applications where power loss needs to be minimized. It also offers high reliability and long life span, as it is made of highly durable Tantalum material. Furthermore, its small size and low profile make it perfect for use in portable electronics, where space is often at a premium.

In conclusion, T491C155M035ZTZB01 belongs to the Tantalum capacitors family and is mainly used in power supply and audio applications as a by-pass capacitor and DC blocking capacitor, respectively. Its operations are based on the electrical double layer capacitance (EDLC) effect that helps store energy within the electrical field created when an applied voltage is introduced. The capacitor has a very low ESR rating and high maximum ripple current, making it an ideal choice for a variety of applications where space constraints or power loss needs to be minimized.
