Tantalum capacitors are an indispensable part of most electronic devices, providing electrical energy storage and conditioning in a wide variety of applications. The M39003/03-4076/HSD, a tantalum capacitor, offers the user a number of advantages, including improved performance, lower costs, and smaller size. Understanding the application field and working principle of this capacitor can provide users with the necessary information to gain the maximum benefit from its usage.

Application Field

Adapted from standard military grade tantalum capacitors, the M39003/03-4076/HSD is an excellent choice for a variety of applications, especially those that require reliability and cost effectiveness. This capacitor is extensively used in many different industries, most notably within audio frequency power supply decoupling applications, low power high speed digital circuitry, as well as automotive electronics. Additionally, the M39003/03-4076/HSD can be found in industrial electronics, medical equipment, and most consumer electronic products.

Working Principle

The M39003/03-4076/HSD is a polarized electrolytic capacitor that uses a tantalum plate as its anode (positive electrode) and a porous dielectric oxide film as its cathode (negative electrode). An electrolyte composed of manganese dioxide is then applied between the two electrodes, acting as an ion bridge and allowing the ions to pass between them. This enables the capacitor to store its charge.

In normal operation, electric current flows from the anode to the cathode, and the capacitor charges and discharges accordingly. However, since the capacitor is polarized, the anode must always have a greater potential than the cathode in order for the capacitor to store a positive charge. This difference in potential across the electrodes is known as the capacitor\'s voltage rating, and this must always be kept within specified safe levels.

The M39003/03-4076/HSD capacitor also has a low-temperature coefficient, meaning it is able to hold its charge even when the ambient temperature is fluctuating. The capacitor also has excellent insulation properties, allowing it to maintain its charge even under higher resonant frequencies, making it ideal for audio power supply decoupling applications.

Due to their low cost and small size, tantalum capacitors are becoming increasingly popular for a wide range of applications, and the M39003/03-4076/HSD is no exception. This capacitor provides users with the reliability, performance, and cost effectiveness that they are looking for in a tantalum capacitor, making it the perfect choice for many applications.
