Tantalum Capacitors

Tantalum capacitors are widely used in many consumer and industrial applications. Typically, they are used to produce both high- and low-level electrical and electronic circuits, including those used in power supplies, signal processing, and audio equipment. The M39003/01-2694H is a type of tantalum capacitor, and is used in some of the more demanding applications.

M39003/01-2694H Applications

The M39003/01-2694H is a high performance differential-mode electrolytic capacitor. It is a small size, molded device designed for use in high voltage applications, such as in high-voltage power supplies, medical imaging systems, aircraft instrumentation systems, and communication radar systems. Its ability to operate with high input/output voltages (up to 350 volts) and high ripple current capabilities (up to 2.5 amps) makes it suitable for these types of applications.

The M39003/01-2694H is also suitable for smaller equipment such as personal electronics. It offers low voltage loss and current leakage, which makes it suitable for use in portable devices such as laptops, mobile phones, and PDAs. Due to its small size and low ESR, it is also suitable for use in integrated circuits (IC) and hybrids.

M39003/01-2694H Working Principle

The working principle of a tantalum capacitor revolves around a solid electrolyte material, usually tantalum pentoxide. A small amount of electrolyte is layered between each conductive plate, providing the electric current pathway inside the capacitor.

The two conductive plates of the capacitor are made of two different materials. One plate is made of anoxidised tantalum, while the other is made of an electroless nickel-plated manganese dioxide suspension. The two plates are further separated by insulation spacers, which prevent electric current from flowing through the capacitor in the opposite direction.

When an AC voltage is applied across the two plates, the current passes through the electrolyte layer and forms a capacitor. This capacitance increases when the electric field intensity rises. The value of the capacitance depends on the dielectric strength of the electrolyte material, the plate size and spacing, and the operating frequency.

As the energy stored in a capacitor increases, the amount of charge it can hold also increases. This is known as the charge capacity. The M39003/01-2694H has an excellent charge capacity, making it suitable for high voltage applications.

Conclusion

The M39003/01-2694H is a high performance differential-mode electrolytic capacitor widely used in many consumer and industrial applications. It is suitable for use in high-voltage power supplies, medical imaging systems, aircraft instrumentation systems, communication radar systems, and other electronic circuits. Its small size and high charge capacity make it suitable for use in portable devices as well. Its working principle is based on the solid electrolyte material usually tantalum pentoxide, and its capacitance can be adjusted by adjusting the dielectric strength and the distance between its conducting plates.
