Tantalum Capacitors: M39003/01-2790H Application Field and Working Principle

Tantalum capacitors, also known as Ta-capacitors, are electrochemical capacitors created using tantalum foil with an oxide dielectric layer. They are extremely small and have relatively stable electrical properties, making them popular for a variety of electronic applications. The M39003/01-2790H specific properties make them particularly useful in computer peripherals, automotive systems, and power supplies. This article will discuss the different application fields of the M39003/01-2790H, as well as its working principle.

Applications

The M39003/01-2790H is one of the most commonly used tantalum capacitor models due to its high capacitance and low parasitic inductance. It is often used in high-frequency computer and communication circuits, such as VHF amplifiers and transmitters. Because of its dense packaging, the M39003/01-2790H is also suitable for use in high-density circuit boards. It is frequently used in radio frequency (RF) circuits such as low-frequency voltage-controlled oscillators (VCOs), voltage-controlled amplifiers (VCAs), and low noise/low pass filters.

Another common application for the M39003/01-2790H is on automotive platforms where its small size and low inductance make it ideal for use in cramped spaces. It is often used in motor drive circuits, such as EGR valves, fuel injectors, antilock brakes, cruise control systems, and other applications. Additionally, it is perfect for power supplies used in medical, military, and aerospace applications.

Working Principle

At the most basic level, the M39003/01-2790H tantalum capacitor works in the same way as other capacitors. Like regular capacitors, it uses an oxide-based dielectric to store electric charge. However, because of its small size and tight packaging, the capacitance of the M39003/01-2790H is much higher than regular capacitors. The high capacitance allows the M39003/01-2790H to store more charge, and therefore more energy, in a smaller space.

When an electric current passes through the device, a potential difference is created across its two ends. This potential difference allows electric charge to flow from one end to the other, resulting in a current. The amount of current that can flow across the device depends on the capacitance of the device and the amount of charge that it can hold.

The M39003/01-2790H also has exceptionally low parasitic inductance, making it a good choice for high-frequency circuits. The low inductance allows the device to respond to higher frequencies without losing its capacitive properties. This makes the M39003/01-2790H a very desirable component for use in high-frequency computer and communication circuits.

Conclusion

The M39003/01-2790H tantalum capacitor is a versatile and reliable component that can be used in a variety of electronic applications. Its small size, high capacitance and low parasitic inductance make it well suited for high-density circuits and high-frequency applications. Additionally, its robust and stable construction make it a great choice for automotive, medical, military, and aerospace applications.
