Tantalum - Polymer Capacitors

T540B107M004CH85107280 is a type of tantalum-polymer capacitor, which is characterized by its high capacitance and low equivalent series resistance (ESR). This makes it especially suitable for applications in the communication, computer and consumer electronics industries. As with other types of capacitors, the T540B107M004CH85107280 is designed to store electrical energy and then release it. The capacitor provides the same function as a rechargeable battery in an electronic circuit, but can only be used in certain types of electronics.

Application Field

The T540B107M004CH85107280 is especially suitable for use in radio frequency (RF) circuits. Its low ESR makes it ideal for use in high-frequency or low-frequency applications, such as low-noise amplifiers, switched-mode power supplies and mobile phone base station circuits. It is also highly useful in signal processing circuits, such as digital-to-analog converters, signal synthesizers and digital-to-analog converters.

The T540B107M004CH85107280 also has applications in consumer electronics, such as digital audio and video players, digital cameras, and other consumer electronics that require low standby current and high output current. It is also suitable for use in medical-grade equipment, where its low ESR makes it suitable for use in ECG monitors and other medical monitoring systems.

Working Principle

As a tantalum-polymer capacitor, the T540B107M004CH85107280 is composed of two pieces of tantalum foil separated by a dielectric polymer. The basic structure of the capacitor is the same as a traditional tantalum capacitor, but the use of a polymer dielectric offers enhanced electrical properties. When a voltage is applied across the capacitor, it stores the electrical energy in the form of an electric field. When a current is applied, the capacitor acts like an inductor, releasing the stored energy in the form of an electrical current.

The dielectric polymer used in the T540B107M004CH85107280 offers superior characteristic impedance and ESR, which makes it suitable for use in high-frequency circuits. To minimize the capacitor\'s ESR, its dielectric is designed with a thin layer of metal oxide to reduce the dielectric grain size and capacitance. This ensures that the capacitor releases energy in the form of a clean, stable waveform.

The T540B107M004CH85107280 features a range of voltage ratings and temperature ratings, allowing it to be used in a variety of different applications. Its long-term reliability and low leakage current make it an ideal choice for a variety of applications in the communication, computer, and consumer electronics industries.
