Tantalum capacitors are one of the most popular capacitor types in the market, offering reliable operation and low profile package. The T491A155M035AT is a tantalum capacitor with a voltage rating of 16 VDC. It offers a high ripple current capability, making it suitable for a variety of applications, including filtering, buffering, and decoupling.

The T491A155M035AT is a Type A, long lead time, molded high CV (capacitance voltage) product constructed using a tantalum anode and a charge-balanced electrochemical construction a.k.a. sintered anode. The series features higher ripple current capability, tight capacitance tolerance, excellent high frequency performance and superior temperature characteristics.

The T491A155M035AT capacitor is made of tantalum, an element with unique capacitance characteristics that give the capacitor a broad range of applications. Tantalum capacitors have a low equivalent series resistance (ESR) and equivalent series inductance (ESL), so it can store more energy than any other type of capacitor. Tantalum capacitors are well-suited for operation in harsh environments and have a higher capacitance compared to other capacitor types. The T491A155M035AT series features a maximum capacitance of 0.22μF along with a maximum operating temperature of 125℃, making it ideal for high-temperature applications.

The working principle of the T491A155M035AT depends upon the electrochemical processes between the electrodes of the capacitor and the dielectric material. When a voltage is applied across the electrodes of the capacitor, an electrical field is created. The electric field draws electrons from one side to the other, creating an electric charge. This charge then produces an electrical current which gradually reduces until a stable voltage is reached.

The T491A155M035AT is designed for general purpose decoupling, filtering, and buffering applications. It is a versatile and reliable capacitor, providing stability, reliability, and long life. It is used in applications such as signal conditioning, signal processing, automotive and telecom circuit designs, linear power supplies, memory voltage regulators and DC-to-DC converters. The T491A155M035AT is available in either a through-hole or surface mount configuration is a standard 150mil/3.86mm size.

The T491A155M035AT is a high-quality, reliable capacitor type, offering excellent ripple current performance, wide temperature range, and tight capacitance tolerance for a variety of applications. It is a great choice for filtering, buffering, and decoupling applications, as it offers low equivalent series resistance and excellent temperature characteristics for increased reliability.
