M39006/25-0052 Capacitors

Tantalum capacitors are a type of capacitor that has been around since 1967. They are known for their high power output, excellent reliability, and wide temperature range of operation. The M39006/25-0052 is one of the most commonly used tantalum capacitors and is used in a variety of applications. This article will discuss the application field and working principle of the M39006/25-0052.

Tantalum Capacitors & Their Applications

Tantalum capacitors are primarily used in power electronics applications. This could include main power supplies, motor drives, high voltage power supplies, communication and industrial equipment, computer peripherals and more. They are also used in automotive and aerospace applications due to their long-term stability and reliability.

The M39006/25-0052 is a high power, low profile tantalum capacitor, making it an ideal choice for many applications. It is particularly well-suited for use in high current and high voltage circuit configurations, due to its low equivalent series resistance (ESR) and ripple current capabilities. The capacitor is also able to handle up to 2.5A of ripple current and can operate at temperatures up to 125°C.

Working Principle

The M39006/25-0052 contains two tantalum electrodes, formed from foils. The two electrodes are separated by a dielectric material, usually a semiconducting material such as tantalum oxide. When a voltage is applied to the capacitor, the tantalum oxide dielectric material creates an electric field between the two electrodes, which in turn creates an electrical charge. This process is called dielectric polarization. The electric field created by the dielectric material will increase as the applied voltage increases.

The capacitor also has a voltage rating, which is the maximum voltage it can sustain. If the voltage applied to the capacitor exceeds the voltage rating, the dielectric material will break down, resulting in the capacitor permanently sustaining a fault and potentially causing damage to the surrounding circuitry.

In order to prevent this from occurring, the M39006/25-0052 is designed with a surge voltage protection circuit. This protection circuit is designed to momentarily stop the current flow through the capacitor if the applied voltage exceeds the voltage rating. This will prevent the capacitor from sustaining any permanent damage.

Conclusion

The M39006/25-0052 is a high power, low profile tantalum capacitor ideal for high current and high voltage circuit configurations. The capacitor can withstand temperatures up to 125°C and has a voltage rating of 2.5A. It also has a surge voltage protection circuit to prevent the capacitor from sustaining any permanent damage if the voltage exceeds the rating.
