Tantalum Capacitors

Tantalum capacitors, also known as manganese dioxide capacitors, are constructed with tantalum metal which act as the anode for the capacitor and are formulated with manganese dioxide as the dielectric material. The use of tantalum as the anode material gives these capacitors a high capacitance-to-volume ratio, making them the ideal choice for applications with high density requirements. These capacitors are typically used in switching power supplies, telecom equipment, computers, and medical equipment.

M39003/01-5713 Application Field and Working Principle

M39003/01-5713 is a series of polymer tantalum capacitors with a variety of voltage ranges and capacitance values. These capacitors are designed to operate in applications that require high capacitance, temperature and long-term reliability. They come in various sizes and are constructed with the proven solid polymer, which is an extremely reliable solid electrolyte.

Tantalum capacitors have many features that make them attractive for use in demanding applications. M39003/01-5713 series of polymer capacitors offer excellent electrical and mechanical characteristics, providing excellent low impedance and thermal stability. The combination of tantalum and manganese dioxide as the dielectric gives M39003/01-5713 capacitors an ideal performance in applications that are subject to low impedance. The capacitors also feature an internal forming process that ensures reliable and stable capacitance across frequency and temperature.

M39003/01-5713 capacitors come in two different types: wet slug and dry slug. The wet slug type is filled with a liquid electrolyte and provides higher capacitance values at lower voltage ratings. The dry slug type is filled with a solid dielectric, and provides excellent reliability and stability.

The working principle of M39003/01-5713 capacitors is based on their ability to accumulate charge on the plate and store it as electrical energy. This is achieved by generating a change of potential (voltage) across the capacitor when the charge is applied. This voltage will then remain over the capacitor for a short period of time until the capacitor begins to discharge. During this displacement process, charge is transferred from one plate to another, eventually leaving no charge.

The M39003/01-5713 series of capacitors are able to provide a high capacitance to voltage ratio and are therefore ideal for a variety of applications such as power supplies, telecom equipment, computers, medical equipment, audio/video equipment, and anything else requiring high-density power. They provide long-term reliability and have proven to be an excellent choice for applications demanding long life.
