Tantalum Capacitors: M39003/03-2012 Application Field and Working Principle

Tantalum capacitors are a type of electrolytic capacitor, a component that acts as a charge storage device. Also known as a tantalum electrolytic capacitor, this type of capacitor is composed of two electrically conductive elements, referred to respectively as the anode and cathode. These elements are separated by an insulating electrolyte.Tantalum capacitors are typically polarised, meaning that they are designed to work in circuits with an accurate polarity. This makes sure that the voltage across the capacitor is always directed in a consistent way, ensuring a uniform flow of current. When making a selection from the M39003/03-2012 series, attention must be paid to ensure that the part is correct for the intended application.Tantalum capacitors from the M39003/03-2012 series are generally suitable for use in circuits in which the current at startup is high and can be used as components in applications such as military aircraft, avionics, medical devices, and astronautics.Tantalum capacitors from the M39003/03-2012 series are also used in the mobile phone, GPS, and other related electronic products. These capacitors feature a tantalum core surrounded by a layer of anodized aluminium oxide. This oxide layer forms the capacitor\'s dielectric material, meaning that it provides insulation between the core and outer contacts.The M39003/03-2012 series of capacitors are constructed using a sintered anode which means they are also known as sintered tantalum capacitors. This type of construction provides superior stability, excellent high-temperature performance, and a high capacitance per unit volume.Tantalum capacitors from the M39003/03-2012 series are a great choice for applications requiring high levels of reliability, cost-efficiency, and performance. They offer excellent electrical performance, including high capacitance, low ESR, and extremely low self-induction. Due to their relatively high-level of stability, they are also suitable for use in AC power applications.The working principle of tantalum capacitors from the M39003/03-2012 series can be explained by examining the structure of the capacitor in more detail. When an electrical voltage is applied to the anode, the current flow is resisted by the oxide layer. This in turn causes a small amount of dielectric polarization, which then results in a capacitance change. As the voltage across the capacitor then increases, the oxide layer resists the flow of current more, thus further increasing the capacitance.As previously mentioned, tantalum capacitors from the M39003/03-2012 series offer excellent levels of performance and reliability. This can be explained by examining the unique construction of the oxide layer, which is stable at a wide range of temperatures, and also offers a high dielectric strength. This ensures that the capacitor performs consistently in various environments.In addition to this, the tantalum capacitors from the M39003/03-2012 series are often used for their excellent low ESR, meaning that they can be used in high-frequency applications such as GPS receivers and communication systems. As well as this, they are also used for their relatively low self-induction, meaning that they require a relatively low current to charge and discharge.To summarise, tantalum capacitors from the M39003/03-2012 series offer a wide range of benefits, making them a popular choice for high-reliability circuits. Their superior stability, high capacitance, low self-induction, and low-ESR make them an ideal choice for a variety of applications, including medical, avionic, and electronic/digital systems.
