Introduction to Tantalum - Polymer Capacitors

Tantalum-polymer capacitors are a type of electrolytic capacitor that are composed of an oxide layer on a tantalum anode and a solid electrolytic polymer cathode. They offer improved performance over traditional tantalum capacitors, as well as a wider range of capacitance and operating temperature ranges. This makes them an ideal choice for applications such as power supply filtering and frequency stabilization. In this article, we will look at the T543X226M063ATS0757280 application field and working principle.

Tantalum - Polymer Capacitors

Tantalum-polymer capacitors are made of two layers of material, a non-conductive solid polymer cathode and a conductive tantalum anode. Between these two layers there is a conductive oxide layer which forms the connection between the two. This oxide layer acts as a dielectric, allowing current to flow between positive and negative poles of the capacitor and providing an electrical field for storing energy. Due to the geometry of the layers, the capacitance of the device will increase exponentially according to the voltage applied. Compared to traditional tantalum capacitors, tantalum-polymer capacitors have the benefit of increased capacitance and wider voltage ranges, as well as a longer life expectancy and improved performance at higher temperatures. This makes them suitable for applications such as filtering of power supplies and stabilizing of frequencies.

T543X226M063ATS0757280

The T543X226M063ATS0757280 is a tantalum-polymer capacitor with a low ESR (equivalent series resistance) and excellent performance in decoupling applications. The device has a wide temperature operating range of −55°C to +105°C, so it is suitable for many applications, including automotive and industrial environments. It has a capacitance of 2.6 μF and a maximum voltage rating of 16 VDC and is 100% surge-tested for Long Term Stability and Reliability.The device is particularly well-suited for decoupling applications, as it can supply high-quality bypass capacitance to ground from a DC power supply line and provide effective impedance control. This helps to reduce the output noise and instability of the system.

Working Principle

When voltage is applied to a tantalum-polymer capacitor, two things happen. Firstly, a conductive oxide layer forms on the anode and a solid electrolytic polymer layer forms on the cathode. This forms the electrical connection between the two layers. Secondly, the electric field created by the voltage causes ions to move through the oxide layer and form a charge distribution between the two electrodes. This charge distribution creates an energy storage effect, allowing the device to act as a capacitor.When a current is applied to the capacitor, the charge stored in it dissipates as current through the components connected to the terminals. This process is called capacitive current flow, and it works to filter out unwanted signals from the system, like AC noise and ripple.

Conclusion

In conclusion, tantalum-polymer capacitors like the T543X226M063ATS0757280 are ideal for filtering power supplies and stabilizing frequencies. They have the advantage of increased capacitance and wider voltage ranges, as well as longer life expectancy and improved performance at higher temperatures. The device is particularly well-suited to decoupling applications, as it provides high-quality bypass capacitance to reduce output noise and improve system stability.
