Tantalum capacitors are an essential component of many electronic circuits. They offer improved performance and reliability compared to conventional aluminum electrolytic capacitors, due to their superior capacitance and lower ESR (equivalent series resistance). The M39003/01-5698 is a tantalum capacitor designed to meet the specific needs of high power applications, where considerable energy must be stored or dissipated in a reliable and efficient manner. This article will explain the M39003/01-5698’s application field and working principle.

Application Field

The M39003/01-5698 is a surface-mount capacitor designed to meet the exacting requirements of desktop computers and other power-hungry applications. It comes in a small, corrosion-resistant package that allows it to be easily mounted onto a circuit board. The capacitor features low ESR and high capacitance, which make it ideal for power-supply and UPS-regulated systems. It is also capable of providing a low equivalent series resistance value, which enables it to handle high amounts of energy. The capacitor\'s low inductance ensures minimal power supply noise and distortion.

The capacitor can also be used in digital signal processing (DSP) applications, such as audio amplifiers, as it offers low ESR and high capacitance, making it ideal for storing large amounts of energy for short periods of time. It is also highly recommended for use in switching power supplies where it can provide a low ESR, enabling the power supply to operate at higher frequencies with less ripple. Additionally, the capacitor is also well-suited for temperature sensing applications, due to its low temperature coefficient.

Working Principle

A tantalum capacitor works by creating a dielectric barrier between two separated surfaces of a conducting material. This dielectric barrier is formed when a negative anode and a positive cathode are separated by an insulator. When an electric potential is applied between the two electrodes, the insulating dielectric will build up between them, creating a capacitance. This capacitance is responsible for storing electrical energy and allowing it to be discharged in a controlled manner.

The M39003/01-5698 is a solid, surface-mount tantalum capacitor that is designed to provide high power density and low ESR values. The capacitor is constructed with a “leaky” dielectric, which means that when the capacitor is charged, the electrons will slowly leak out over time. This is beneficial because it helps keep the capacitance stable and prevents voltage spikes from occurring. The leaky dielectric is also designed to absorb electrical surges, protecting the circuit from damage.

In order to ensure reliability and increased energy density, the M39003/01-5698 is constructed with a cap design that allows for the internal electrodes to be connected directly to the terminals, reducing resistance and improving energy storage. Additionally, the capacitor is designed with an integrated ESR-reduction feature, which allows for reduced overall ESR values and increased efficiency.

The unique construction of the M39003/01-5698 makes it an ideal choice for high power design requirements. Its superior capacitance and low ESR makes it an excellent choice for applications where large amounts of energy need to be stored and discharged in a reliable and efficient manner. This is why the capacitor is often used in power supplies, UPS-regulated systems, digital signal processing, and temperature sensing applications.
