Tantalum capacitors are a form of electrochemical capacitor which use tantalum as the anode and an oxide layer as the dielectric material, formed on the anode. They are widely used in portable and consumer electronics, especially in cell phones, due to their small size and low cost. The M39003/03-0307H is one such device, designed for high-frequency, high-reliability applications.

The M39003/03-0307H is made from tantalum pentoxide (Ta2O5) and coated with an electrolyte to form a highly stable dielectric layer. The device is encased in a small, hermetically-sealed package, typically with two leads or contacts. The leads provide a convenient way to connect the capacitor to an electronic circuit.

Application Field

The M39003/03-0307H is an ideal capacitor for high-frequency, high-reliability applications, such as radios and other communication equipment. Due to its small size and low cost, it is widely used in portable and consumer electronic devices, particularly in cell phones. The device is also used in power supplies, medical equipment, and other applications that require low power consumption and high capacitance.

Working Principle

Tantalum capacitors rely on the realization of the principle of capacitance, a basic electrical property in which two parallel metal plates separated by a dielectric material forms an electrical element capable of storing energy. In this device, the parallel plates are formed by two nickel-plated tantalum electrodes, while the dielectric material is a layer of tantalum pentoxide, which is formed by an electrolyte-based coating process.

When an electric charge is applied to the device, the plates become electrically polarized, and the ionic charge is stored in the dielectric layer. When the applied voltage is removed, the dielectric layer retains its charge, and the tantalum capacitor “holds” the stored voltage. This makes the device ideal for applications such as radiators and other devices that use a steady voltage.

Conclusion

The M39003/03-0307H is a highly reliable, low-cost, high-frequency tantalum capacitor. It is ideal for applications such as radios, cell phones, and other communication equipment, as well as power supplies and medical equipment. The device works by utilizing the electrical property of capacitance, which is a form of electrical storage based on two parallel plates separated by a dielectric material. The two plates in this device are formed by two nickel-plated tantalum electrodes, while the dielectric material is a layer of tantalum pentoxide.
