Tantalum capacitors are electronic components used in electronic devices. They are available in a variety of shapes and sizes and can be used in a wide range of applications. The TH3A105M025D5200 is one type of tantalum capacitor that has unique characteristics. This article will discuss the application field and working principle of the TH3A105M025D5200.

Application Field

The TH3A105M025D5200 is a miniature high-temperature, epoxy-filled, molded tantalum capacitor. It has a high frequency, high pulse current, high stability, and high reliability, making it suitable for use in high-temperature environments and high frequency circuits. It can also be used in applications that require a low equivalent series resistance (ESR). Some of the most common applications of the TH3A105M025D5200 include high-temperature power supply regulation, high-frequency signal processing, signal amplification, data acquisition systems, and transistor radio and power amplifier circuits.

Working Principle

The TH3A105M025D5200 operates on the principle of dielectric absorption. A prismatic capacitor is made up of two internal layers, one consisting of a dielectric material and the other consisting of two pieces of foil. These two layers are separated by a dielectric material, and the entire structure is encased in an epoxy resin. As current is applied, an electric field is created within the capacitor, resulting in the dielectric material becoming more conductive and absorbing the energy.

The current applied to the TH3A105M025D5200 can be either direct current (DC) or alternating current (AC). When the current is applied, a voltage (hysteresis) is created in the dielectric material, which stabilizes the voltage across the second layer, allowing current to flow continuously. As the current is removed, the voltage across the capacitor falls rapidly and the capacitor is left with a residual charge.

The TH3A105M025D5200 capacitor is also designed to prevent against electrical overstress (EOS). The addition of a negative temperature coefficient, which reduces the capacitance value as the temperature rises, prevents the capacitor from being damaged by sudden temperature spikes. In addition, the capacitor has an internal protective coating that guards against voltage over-pressure.

The TH3A105M025D5200 tantalum capacitor is an excellent choice for high-frequency, high-temperature applications. Its low ESR and resilience to EOS make it a reliable solution in a wide range of applications. Whether you are looking for a solution for your high-temperature power supply regulation or signal amplification, the TH3A105M025D5200 is an excellent choice.
