Introduction

Tantalum – Polymer capacitors, or Ta-Poly capacitors, are capacitors used primarily in electronics and military applications. This type of capacitor contains two or more layers of solid material, generally referred to as an anode and a cathode, between which a dielectric material is sandwiched between them. This type of capacitor is particularly used because of its higher temperature stability, higher capacitance per unit volume, and its low self-discharge rate. Due to their lower characteristic losses at higher frequencies, they are especially useful in communications applications.One specific example of a Ta-Poly capacitor is the T541X107K0DT8710. It is a radial-leaded tantalum capacitor with a polymer dielectric that offers solid electrical performance. It has a capacitance tolerance of ±10%, and an operating temperature range of -55°C to +85°C. The capacitor has an ESR of 0.04 ohms, and an ERI of 0.68 ohms.

T541X107K0DT8710 Application Field and Working Principle

The T541X107K0DT8710 can be used in the following fields: Automotive, Industrial Control, Military equipment, Consumer electronics, etc. In automotive applications, it provides high capacitance, low ESR, and excellent temperature cycling/stability. It is widely used as a decoupling capacitor in automotive switching power converters, engine control units, and other automotive electronics. The T541X107K0DT8710 provides a reliable and consistent performance in industrial control and military equipment. In these settings, the T541X107K0DT8710 is utilized to filter, decouple and stabilize sensitive circuits. In consumer electronics, it performs the same roles as in industrial control, but also tightly controls and regulates power conditions in order to maintain system performance and stability. The basic principle of all capacitors is the same, regardless of type. The capacitor stores electric charge when a voltage is applied, and releases the stored charge when the voltage is removed. The capacitor consists of two metal plates, with a dielectric material (in this case polymer) sandwiched between them. When voltage is applied, electric charges are stored on both plates, creating an electric field between them and the dielectric material. This is how the capacitor stores energy. When the voltage is removed, the capacitor releases the stored charge and reverts back to its original state. The T541X107K0DT8710 capacitor has a high capacitance tolerance (±10%), making it an ideal capacitor for applications where precise control of capacitance is needed.

Advantages of Tantalum - Polymer Capacitors

Compared to other types of capacitors such as aluminum electrolytic capacitors and ceramic capacitors, Ta-Poly capacitors offer a number of advantages. These include:

• Higher temperature stability
• Higher capacitance per unit volume
• Low self-discharge rate
• Lower characteristic losses at higher frequencies

The high temperature stability of or Ta-Poly capacitors makes them ideal for use in high temperature environments such as automotive and military applications, where there is a greater risk of thermal stress. The high capacitance per unit volume allows for higher levels of capacitance in a smaller size, which is important for reducing circuit board space requirements. The low self-discharge rate allows for longer periods of inactivity before being discharged, making them ideal for applications where long periods of circuit inactivity is common. Lastly, the lower characteristic losses at higher frequencies make them well-suited for use in communications applications as they can provide better signal isolation at higher frequencies.

Conclusion

The T541X107K0DT8710 is a high-performance radial-leaded tantalum capacitor with a polymer dielectric. It is widely used across a variety of different applications, including automotive, industrial control and military equipment, due to its high temperature stability, high capacitance per unit volume and low self-discharge rate. It offers a high capacitance tolerance (±10%) for precise control and also has lower characteristic losses at higher frequencies. As such, it is an excellent choice for use in a wide range of applications requiring high reliability and excellent performance.
