KEMET T520 Series Polymer Tantalum Capacitors: The Perfect Combination of Low ESR and High Performance

As the performance and reliability requirements of modern electronic equipment continue to increase, capacitors, as one of the key passive components, have attracted much attention in terms of technological development. KEMET has introduced the T520 series of polymer tantalum capacitors, which are ideal for many high-performance electronic applications due to their low ESR (Equivalent Serial Impedance), high-frequency performance, and long life. High-performance electronic applications with its low ESR (Equivalent Series Impedance), high-frequency performance and long life.

Technical Characteristics of the T520 Series

Part of the KEMET KO-CAP® (KEMET Organic Capacitor) family, the T520 Series uses a conductive polymer instead of the conventional MnO2 cathode, combining the advantages of multilayer ceramic capacitors, aluminium electrolytic capacitors, and conventional tantalum capacitors. The following are its key technical features: Firstly, the T520 series has an extremely low ESR, which enables it to excel in high-frequency applications, effectively reducing signal loss and improving system efficiency. Second, compared with traditional tantalum capacitors, the T520 series is more reliable, especially in humid or high-temperature environments, and its performance remains stable. In addition, the T520 series supports surface mount design (SMD) and is compact in size, making it ideal for the miniaturisation needs of modern electronic equipment. At the same time, the T520 series has a long life and benign failure mode, effectively avoiding the risk of ignition failure that can occur with traditional MnO2 tantalum capacitors. Finally, this series of products is RoHS compliant, halogen-free, and has passed a number of environmental tests, making it a green solution.

Typical Application Scenarios

With the above technical advantages, the T520 series is widely used in electronic devices that require high performance and reliability. For example, in the field of consumer electronics, it is often used in smartphones, laptops and tablets to provide stable power filtering and decoupling for these devices. In solid state drives (SSDs), it can effectively support power management during high-speed data transfer. In addition, in communication devices such as base stations and network equipment, it can meet the demand for low noise and high efficiency for complex signal processing. In the field of automotive electronics, the T520 series is also widely used in in-vehicle entertainment systems and navigation equipment to provide reliable support for these critical systems.

Popular Models and Parameters

The T520 series covers a wide range of needs from low to medium-high voltages and from small to large capacities. For example, the T520D337M006ATE045 is a model with a rated voltage of 6.3V, capacitance value of 330µF, and ESR of 45mΩ, making it ideal for scenarios that require a large capacity and medium ESR value. The T520B227M2R5ATE035, on the other hand, is a miniaturised model with a rated voltage of 2.5V, capacitance value of 220µF and ESR of 35mΩ, which can be used in space-constrained applications that require low ESR. In addition, models like the T520V157M006ATE007, with a rated voltage of 6.3V, capacitance value of 150µF, and ESR of only 7mΩ, focus on ultra-low ESR needs and are ideal for use in high-frequency, high-performance designs.

Advantages Compared to Other Types of Capacitors

Compared to conventional MnO2 tantalum capacitors, the T520 Series performs better in terms of ESR, temperature stability, and safety. Their low ESR characteristics provide better signal integrity in high frequency applications, while their benign failure modes significantly reduce risk during use. With higher capacity density, longer life and better temperature stability than aluminium electrolytic capacitors, the T520 series is ideally suited for applications that require prolonged operation and complex environmental conditions.

Summary

KEMET T520 series polymer tantalum capacitors are widely used in consumer electronics, automotive electronics, and communication equipment due to their low ESR, high reliability, miniaturised design, and environmental compliance. It not only optimises system performance, but also reduces component count and PCB area, providing design engineers with a flexible and efficient solution. For the pursuit of high performance and reliability-oriented electronic design, the T520 series is undoubtedly a trustworthy choice.
