Tantalum capacitors are a type of electronic component used in many different types of circuits. Commonly used for their ability to store a charge in an area of the circuit board, they are normally used to filter circuits or create time delays. The T86E476M020EASS is one type of capacitor in the family of Tantalum capacitors and is often found in computers and other consumer electronics. This article will discuss the application fields and working principle of the T86E476M020EASS.

The application fields for the T86E476M020EASS would include computer motherboards, servers, embedded systems, automotive radios, drones, communication systems, among others. This particular capacitor was designed to offer a low-profile surface-mount component with long-term reliability and very low leakage current and insulation resistance characteristics. This makes it particularly well-suited for applications with harsh heat requirements, high vibration, and radiation environments. Additionally, this capacitor features a moldable termination which prevents the hardening of the termination during soldering, making them able to withstand the mechanical fatigue of long-term usage in mobile applications.

In terms of working principle, the T86E476M020EASS uses a solid tantalum electrolyte, with electrodes of either solid or porous tantalum. The solid electrolyte is anodic to the electrodes, which create an electric double layer of capacitance across the solid electrolyte, forming the capacitor. This double-layer capacitance creates a voltage drop across the capacitor, and is known as the “depolarization” of the capacitor. The depolarization of the capacitor works in combination with other properties, such as charge time and the ability to hold charge for extended periods of time, to create the various capacitances and voltages the capacitor is designed to provide.

The T86E476M020EASS is a robust and low-profile surface-mount capacitor designed for use in many different types of consumer electronics. It’s low-profile design makes it ideal for use in space-constrained applications, and high-temperature, high-vibration, and radiation environments. Its solid tantalum electrolyte and electrode material create an electric double-layer of capacitance that allow it to provide low-leakage current and insulation resistance characteristics, while also having a long-term reliability. These attributes make the T86E476M020EASS one of the most reliable capacitors in the family of Tantalum Capacitors.
