Tantalum Capacitors

A tantalum capacitor is a type of electrolytic capacitor that uses a tantalum material as its anode. They are most commonly used for high stability and high reliability applications. The M39003/01-2813/TR is a fixed electrolytic SMT tantalum capacitor. It is designed for high-reliability, high-frequency, and low-impedance applications.

Application Field

M39003/01-2813/TR capacitors are commonly used in a variety of applications, including automotive, audio, communications, computing, consumer electronics, medical equipment, military, instrumentation, robotics, and more. These capacitors are ideal for high-frequency applications, such as RF/microwave, high frequency AC/DC converters, and other high frequency power applications.

M39003/01-2813/TR tantalum capacitors have a wide operating temperature range from -55 °C to +125 °C, making them suitable for a large number of temperature-sensitive applications. They also offer a high level of reliability due to their low leakage current and high impedance capability.

Working Principle

Tantalum capacitors use a tantalum anode and an electrolyte to create a non-polarized, fixed capacitor. The anode is manufactured from a special formulation of perflouroborate that keeps the capacitor stable and reliable at high temperatures. The anode is then immersed in an electrolyte, and a cathode is placed in contact with the anode.

When a voltage is applied across the capacitor, current flows through the electrolyte, causing an electrochemical reaction. This reaction produces an oxide layer on the surface of the tantalum anode, which acts as a dielectric. The oxide layer stores electrical energy, allowing the capacitor to hold a charge for a fixed period of time.

The oxide formed on the surface of the tantalum anode is very thin, which allows for a low ESR (Equivalent Series Resistance) characteristic. This makes the M39003/01-2813/TR ideal for high-frequency applications, where the capacitors need to charge and discharge quickly. The capacitors can also handle high temperatures and vibrations, making them suitable for a variety of environments.

M39003/01-2813/TR capacitors are also known for their high level of reliability, making them suitable for applications such as medical equipment, automotive, and military applications.

Conclusion

M39003/01-2813/TR tantalum capacitors are used in a wide range of high-reliability applications. They offer a low ESR characteristic, making them suitable for high-frequency applications, as well as a wide operating temperature range and high level of reliability. These capacitors are used in a variety of applications, from automotive, audio, communications, computing, consumer electronics, medical equipment, military, instrumentation, robotics, and more.
