Tantalum-polymer capacitors, also referred to as polymer tantalum capacitors, are a type of capacitors that use a solid organic polymer to enable electrolytic action. They are used for applications that require a large amount of electrical current and higher voltage stability. The T540D477K004BH85107610 is an example of this type of capacitor. Its application field and working principle will be discussed in the following sections.
The wide range of industries in which tantalum-polymer capacitors are used includes military, aerospace, automotive, telecommunications, audio, consumer electronics and medical fields. These capacitors are ideal for high frequency, high current and high temperature operating environments. For example, in the audio industry, they are used in the design of amplifiers, speakers and other audio equipment. In the medical field, they are used in the design of medical imaging devices and other medical equipment, where reliable performance and stability are essential. In the automotive and telecommunications fields, these capacitors are used to provide power in applications such as driving motors or controlling signals in communication systems.
One of the main advantages of tantalum-polymer capacitors over other types of capacitors is their compact size and light weight. This makes them ideal for applications that need to be integrated with other components in tight spaces. For the same reason, tantalum-polymer capacitors are capable of sustaining high current and high temperature operating environments. Additionally, these capacitors typically provide stable capacitance performance and very low equivalent series resistance (ESR).
The T540D477K004BH85107610 is a type of radial-leaded tantalum-polymer capacitor with a voltage rating of 4.7V, a capacitance of 0.47µF, a lifetime of up to 10000 hours, and a maximum temperature rating of 85°C. The capacitor features two leads for easy installation and connection to a circuit.
The working principle of tantalum-polymer capacitors relies on the difference between the electrochemical properties of the solid organic polymer and the electrolytic action of the solution in which it is immersed. When a voltage is applied, the positively charged ions in the electrolyte solution are attracted to the negative electrode (cathode), and the negatively charged ions are attracted to the positive electrode (anode). This creates a temporary electrical bridge between the two electrodes, allowing current to flow through the capacitor.
The strength of the electric field created by this electrical bridge is inversely proportional to the capacitance of the capacitor, meaning that a larger capacitance results in a weaker electric field and vice versa. Choosing the correct capacitance value for the application is important to ensure that the capacitance is not too high or too low, resulting in inefficient performance or damaging the circuit.
One of the main advantages of tantalum-polymer capacitors is their low ESR and excellent long-term frequency stability. This makes them ideal for applications that require precise frequency control and reliable performance over long periods of time. In addition, these capacitors are capable of providing a rapid charge/discharge cycle without sacrificing performance. This makes them ideal for power management applications, where the capacitor acts as an energy reservoir to supply power when it is needed the most.
The T540D477K004BH85107610 is a reliable and durable tantalum-polymer capacitor ideal for a variety of applications. Its wide operating temperature range and excellent frequency stability make it an ideal choice for applications in the medical, automotive, telecom, and audio industries. The high surge current capability makes it suitable for high-power management applications where precise frequency control and reliable performance are essential.
