Tantalum Capacitors

Capacitors are electrical components that are used to store electrical energy in an electric field. A tantalum capacitor is a type of capacitor that is composed of tantalum and has a relatively high capacity to store electrical energy. The M39003/01-5218H tantalum capacitor is a component manufactured by The Columbus Co. made for use in military and aerospace applications.

Applications

The M39003/01-5218H tantalum capacitor is designed for a variety of applications in both the military and aerospace industries. It is suitable for use in heavy-duty military electronic equipment, as well as in aviation electronics and satellite control systems. In addition, the M39003/01-5218H has a wide operating temperature range of -55°C to +130°C, making it an ideal choice for use in extreme temperature applications such as those encountered in the aerospace industry.

Design Specifications

The M39003/01-5218H tantalum capacitor has an extremely small form factor, measuring just 0.22 inches in length and 0.14 inches in width. It is a surface-mounted component and features a nonmagnetic design, making it suitable for use in equipment subject to magnetic fields. In addition, its low profile design helps to minimize the overall size of the system in which it is used.

The M39003/01-5218H tantalum capacitor has a capacitance rating of 560 µF with a rated voltage of 25V and a maximum voltage of 35V. Its capacitance tolerance is ±20% and it has a maximum dissipation factor of 0.07. The M39003/01-5218H also has a low-temperature coefficient, making it an ideal choice for use in temperature-sensitive applications.

Working Principle

The M39003/01-5218H tantalum capacitor works on the principle of electrical energy storage in a dielectric material. The device consists of two metal plates, known as “electrodes”, which are separated by a thin layer of insulation material called a “dielectric”. When an electric potential is applied across the two electrodes, an electric field is created within the dielectric material, resulting in electrical energy being stored within the device. The amount of energy stored is proportional to the capacitance of the component.

The M39003/01-5218H tantalum capacitor is constructed with a tantalum alloy electrode and organic polymer dielectric material. This combination gives it a higher capacitance rating than comparable components made with other material. In addition, the organic polymer dielectric has a lower leakage current, resulting in a longer life and improved performance in high temperature environments.

Conclusion

The M39003/01-5218H tantalum capacitor is a high-performance, small-form factor component suitable for use in military and aerospace applications. Its low profile design and excellent temperature performance make it an ideal solution for applications that require high-density electrical energy storage. The device has a capacitance rating of 560 µF with a rated voltage of 25V and a maximum voltage of 35V, and a low-temperature coefficient. Its construction with tantalum alloy and organic polymer dielectric materials gives the component a long life and improved performance in extreme temperature environments.
