Tantalum - Polymer Capacitors: T521D476M016ATE040 Application Field and Working Principle

Tantalum capacitors incorporate two metal plates, separated by an electrolyte, and an insulating dielectric. These capacitors are used extensively in many types of electronic equipment for their high-power capacity, low leakage current, and long life.The T521D476M016ATE040 is a specific type of Tantalum-Polymer capacitor designed for a wide range of applications. It has a wide voltage range of 4.5V to 16V, low ESR of 0.33 Ohms, and long life of 2,000 hours at 85C. It is capable of handling up to 10A of current, and has a maximum capacitance of 47uF.

The working principle of a tantalum capacitor is based on electrochemical energy storage. When an electrical current is introduced into a tantalum capacitor, the electrons flow through the capacitor, creating an electrical field. This field then creates a chemical reaction in the electrolyte, which releases additional electrons. This process is known as the “Faradaic Effect”. The electron charge is then stored in the capacitor, forming an electrochemical double layer.

The value of the charge stored in the capacitor is directly related to the voltage applied to the capacitor. The higher the voltage, the more charge is stored in the capacitor. This is why it is important to select a capacitor with the correct voltage rating, to ensure that the most amount of charge is stored and the capacitor will not be over-stressed.

The T521D476M016ATE040 capacitor is designed for a wide range of applications including power, energy storage, subsystems, frequency control, and consumer electronics. It has a small size and low height profile, making it ideal for space and weight critical applications. It is also designed to withstand high temperature and humidity, as it is rated to operate up to 85C and 85% Relative Humidity (Damp Heat).

In addition, the T521D476M016ATE040 has excellent stability, with low equivalent series resistance (ESR) and low impedance, meaning the capacitor is able to handle high current applications and provide reliable capacitance for long periods of time. The capacitor is lead-free and RoHS compliant.

Overall, the T521D476M016ATE040 Tantalum Polymer capacitor is an ideal solution for low voltage and high current applications, allowing high performance with reliability. The wide temperature range, long life and low ESR make the T521D476M016ATE040 an excellent choice for many types of electronics.
