Tantalum Capacitors

Tantalum capacitors are one of many types of capacitors. They are a type of electrolytic capacitor, which is a type of capacitor that utilizes a wet electrolyte as the dielectric that is sandwiched between two plates of opposing polarity. These capacitors offer some advantages over traditional film-type and ceramic capacitors, such as higher capacitance per unit volume, higher operating temperature, as well as higher peak current ratings. They can also be made in smaller sizes than traditional film-type capacitors.

M39003/09-0003 Application Field and Working Principle

The M39003/09-0003 tantalum capacitor is a polarized, low voltage, broadband capacitor built for surface-mount applications on printed circuit boards (PCBs). It is made of a capacitively-coupled dielectric material (tantalum) between two plates with opposite polarities. It is sealed for prevention of environmental contamination. The typical operating voltage of this capacitor is 10V.

The two plates of the capacitor act like two oppositely charged plates in a battery, and when a voltage is applied between them, the capacitor exhibits a capacitance, or a change in electric charge. This electric charge can be used to store energy and to act as a filter for signals and noise within electronic circuits. The amount of capacitance (measured in Farads) varies, depending on the size and shape of the capacitor.

The M39003/09-0003 is designed specifically for high-impedance, low-power applications, such as radio-frequency (RF) oscillators, microwave amplifiers, and filters. This allows for clean, efficient operation at high frequencies, reducing the risk of interference and noise that can be caused by other components.

The working principle of the M39003/09-0003 involves the development of a dielectric that is created between two metal plates. The dielectric is charged with a source of electrical energy, and when a voltage is applied, the dielectric stores energy and stores a charge. This stored charge then behaves like a capacitor, allowing for filtering and noise suppression. It can also be used to store energy for longer periods, resulting in longer battery life for portable devices.

Because the M39003/09-0003 is able to withstand higher temperatures, it is often used in higher-temperature applications, where other capacitors may not be suitable. It also has much higher capacitance-to-volume ratios than traditional film-type or ceramic capacitors, making it ideal for space-limited applications such as mobile devices.

In summary, the M39003/09-0003 is a surface-mount tantalum capacitor designed for use in high-impedance, low-power applications. It is able to withstand higher temperatures, has a high capacitance-to-volume ratio, and is suitable for use in space-limited environments. Its benefits include efficient operation at high frequencies, reduced risk of interference and noise, and increased battery life for portable devices.
