Tantalum capacitors are a type of capacitor that offers a high level of reliability and long-term wear-resistance for a given volume. They are widely used for decoupling, noise suppression, transient suppression and tuning applications where a stable capacitance-voltage product is needed for frequency control. The TRJD476K025R0250 is a tantalum capacitor especially designed for a wide range of applications in the electronics industry. This article provides a detailed overview of the application field and working principle of the TRJD476K025R0250.

Application Field

The TRJD476K025R0250 is an especially adapted tantalum capacitor with reliable operation at higher frequencies and higher temperature applications. It features an increased engagement to assure a tight contact between the anode and the cathode. This is especially important to optimize the performance of the capacitor in high frequency applications. The capacitor prevents short circuits, preventing damage to other components. The operating range of the capacitor is between -55°C to 125°C and the capacitance ranges from 10uf to 22uf. It is especially reliable for decoupling, buffering, tuning, and filtering. It can also be used in circuits for RF interference suppression. Additionally, it is beneficial for power conditioning and noise suppression applications.

Working Principle

Tantalum capacitors are polarized capacitors which require an anode (positive side) and a cathode (negative side). The two plates are made of a highly conducting tantalum core with an electrolyte coating. When a voltage is applied, electrical charge is stored in the capacitor, causing an electric filed to be established between the two plates. This field acts as a physical insulation between the plates, creating a dielectric field. The dielectric field then determines the capacitance value of the capacitor. The amount of current stored in the capacitor depends on its capacitance and the applied voltage.

The TRJD476K025R0250 is a radial leaded capacitor, with a positive lead and a negative lead. The positive lead is connected to the anode and the negative lead is connected to the cathode. The contact between the anode and the cathode is increased to ensure that the current flows through the capacitor more efficiently and with less noise. The capacitor is also made of a high quality tantalum core, ensuring that it can handle higher temperatures and frequencies.

In conclusion, the TRJD476K025R0250 is a specialized tantalum capacitor designed to perform in a wide range of applications. It is especially reliable and effective in high frequency applications and can also be used in circuits for RF interference suppression, power conditioning and noise suppression. The capacitance varies between 10uf to 22uf and the temperature range is between -55°C to 125°C.
