Tantalum capacitors, often referred to as Polymer Tantalum Capacitors or Polymer Electrolytic Capacitors, have a wide range of applications in consumer electronic devices, medical devices, automotive electronics, and telecommunications equipment. The M39003/01-7224/TR is a type of Tantalum Capacitor that is especially useful in these applications.

Tantalum capacitors are components that store and discharge energy. They are made up of two metal plates - the anode and the cathode - separated by a dielectric material, typically tantalum pentoxide. This dielectric material has a high dielectric constant, meaning it stores charge comparatively well for a given size.

Tantalum capacitors come in a variety of configurations. The M39003/01-7224/TR is an Axial-Leaded Tantalum Capacitor, meaning that it has two leads on either side of it, resembling the shape of an axle, for easy connection to an application. It is characterized by its capacity of 470uF with a very low maximum impedance (ESL) of 5mohm at 25 degrees Celsius. It is a surface mounted component, so it doesn’t occupy too much space, making it ideal for applications where space is at a premium.

The M39003/01-7224/TR is also noted for its exceptional stability and reliability. It features an ESR (Equivalent Series Resistance) of 7mohm, a temperature range of –55 degrees Celsius to +105 degrees Celsius, and it can withstand up to 20volts of reverse voltage in a single package. This makes it an ideal component for applications where there may be high levels of environmental or electrical stress. Its high frequency performance is also noteworthy, with an excellent capacitance-to-frequency ratio and a low ESR-to-frequency ratio.

The working principle of a Tantalum Capacitor is quite simple and is not dissimilar to that of an electrolytic condenser or a standard capacitor. When a voltage difference is applied across the capacitor, an electric field is formed within its dielectric material, which draws charge to the electrodes. In this way, electric charge is stored and discharged when the electric field is disrupted, allowing it to be used as a power source or energy save. When the capacitor is in a discharged state, the negative charge on the anode plate is attracted to the positive charge on the cathode plate, allowing for the flow of current. When the capacitor is in a charged state, the opposite charges on the plates attract, creating a barrier that prevents current flowing. As current moves between the anode and cathode plates, electrical energy is stored within the Electrolytic Capacitor.

Tantalum capacitors offer a wide range of advantages over other capacitors, such as long-term reliability, high capacitance for a given size, low impedance, and low ESR. The M39003/01-7224/TR is an excellent example of a tantalum capacitor, offering excellent stability, high frequency performance, and high power capabilities. These features make this capacitor suitable for a variety of applications.
