Types of M39003/01-6264/TR Capacitor

The M39003/01-6264/TR capacitor is available in three distinct types. The axial case type is a small-sized symmetrical capacitor, known for its high capacitance-volume ratio. It offers through hole mounting with flexibility in the axial lead length. Meanwhile, the post case type is a mid-to-high voltage device, and it has enhanced dielectric capacitance and leakage current characteristics. The third type is the surface-mount type. It has a large capacitance range for use in high density applications.

Typical Applications

The M39003/01-6264/TR capacitor features a bright anode finish, which makes it suitable for reliable performance in a wide range of applications. Its excellent electrical performance and rugged construction make it a great option for military and aerospace applications, such as missiles and satellites. Apart from that, these components are also popular for use in medical settings, where it functions as a filter, bypass, or isolation capacitor. Moreover, it is common to find the M39003/01-6264/TR capacitor in radio, communication systems, thermocouples, DC-DC converters, inductors, and other electronic passive components.

Working Principle

The M39003/01-6264/TR capacitor is known as an electrolytic capacitors due to its distinct construction. It uses two metallic plates, a dielectric material, and an electrolyte as the medium. When a potential difference is applied to the capacitor, a charge builds up on each plate, and an electric field develops through the dielectric material. The electric field is responsible for storing and releasing the electric energy, which is stored in the form of electrostatic energy.

In a tantalum capacitor, the anode and cathode plates are fabricated from the metal tantalum. The tantalum oxide layer is then formed on the anode surface due to the electrolytic action of the electrolyte. This oxide layer acts as the dielectric material for the capacitor, providing an extremely efficient barrier that prevents electron flow between the two plates. As a result, the component acquires a high capacitance value – much higher than that of other non-electrolytic types.

Conclusion

The M39003/01-6264/TR capacitor is a widely used solid tantalum component, known for its small size, high reliability, and low and stable leakage current. It is available in three types –post case, surface-mount, and axial case– and it is suitable for military, aerospace, and medical electronics applications. Furthermore, owing to its construction with two metallic plates and a tantalum oxide dielectric layer, it acquires a high capacitance value and superior performance.
