Tantalum Capacitors: M39003/01-2356/PR Application Field and Working Principle

Introduction

Tantalum capacitors are electronic components that have the ability to store an electrical charge with a variety of different characteristics. Commonly used in a wide range of products and projects, they are made up of a metalized layer of tantalum sandwiched between two metal sheets. The most common type is the electrolytic capacitor, which is a polarized device with a dielectric oxide layer around a metal plate on the anode. The M39003/01-2356/PR should be considered when looking for a reliable, long-lasting, ultra-compact capacitor. In this article, we will discuss the application field and the working principle of M39003/01-2356/PR.

Application Field

The M39003/01-2356/PR is a compact capacitor designed for high-performance, surface-mount applications that require low-profile solutions. Commonly used in telecommunication and data-processing systems, they are used to maintain tight capacitive tolerance in tight spaces. The capacitor is ideal for applications such as ultrasonic sinks, communications equipment, and switching regulators, where high-frequency signals are processed. It can also be used in audio amplifiers, movers, and other electronics equipment.The capacitor has a high ripple current capability, high frequency stability, and low volume and weight. It is robust and able to withstand extreme temperatures, humidity, and vibration and shock. This makes it suitable for military and aerospace applications, where high performance, reliable operation, and the ability to withstand extreme conditions are critical requirements.

Working Principle

The capacitance of the M39003/01-2356/PR is provided by a thin metalized layer of tantalum sandwiched between two metal plates. The metalized layer is made from an electrolyte oxide and works in the same way as the electrolyte oxide in an electrolytic capacitor. When a voltage is applied to the metal plates, an electric field is created across the tantalum layer. This electric field causes the formation of an oxide layer, which acts as a dielectric, preventing current from flowing through it. The amount of capacitance is determined by the thickness of the layer, the area of the metal plates, and the type of material used.The M39003/01-2356/PR is a polarized capacitor, meaning that it must be connected in the correct direction to get the best results. The anode of the capacitor is connected to the most positive part of the circuit, and the cathode is connected to the most negative part of the circuit. This ensures that the electric field across the tantalum layer is in the correct direction and allows the maximum amount of capacitance to be attained.

Conclusion

The M39003/01-2356/PR is a compact, highly stable, ultra-low-profile capacitor designed for high performance telecommunication, data-processing, and other electronic systems. It has a high ripple current capability, high frequency stability, and low weight and volume, making it suitable for use in demanding military and aerospace applications. The working principle of the capacitor is based on the formation of an electrolyte oxide around a metal plate on the anode, allowing an electric field to be formed across the tantalum layer, creating capacitance. It is important to connect the capacitor in the correct direction to get the best results.
