Tantalum Capacitors

Tantalum capacitors are a specific type of capacitor, developed from the use of tantalum, a solid chemical element, as the primary component of its structure. Tantalum capacitors offer superior performance to other types of capacitors due to their extremely high density, pronounced temperature stability, and wide operating voltage range. The M39003/01-7053H is a tantalum capacitor specifically designed for use in military and aerospace applications.

M39003/01-7053H Application Field and Working Principle

The M39003/01-7053H capacitor is particularly suitable for applications such as avionics, radar, communications, missiles, and small aerospace payloads. It offers an extremely high capacitance at a nominal temperature of -55°C, and a significantly lower equivalent series resistance (ESR) than competing types of capacitors. The capacitor operates in an unipolar mode and features a low leakage current as well as minimal dielectric absorption. The device is composed of a tantalum anode, an electrolyte, and an internal ceramic dielectric. A conductive layer, known as the cathode, is formed on the surface of the anode by applying a layer of tantalum pentoxide, which is then covered by an additional layer of an electrolyte. When a voltage is applied to the device, the tantalum pentoxide layer acts as a dielectric, with electrons travelling through the layer and establishing an electric field. This electric field then creates a capacitance, allowing the capacitor to store electrical energy. The M39003/01-7053H has a nominal capacitance of 12uF, a nominal temperature of -55°C, and an operating voltage of 16V-35V. The capacitor measures 18.4mm x 9.6mm x 5.2mm and weighs 17.2 grams. It has a maximum equivalent series resistance of 4.1mΩ at 100kHz, and a maximum dissipation factor of 0.07%. The temperature coefficient of the unit is ±30ppm/°C, making it highly stable under varying temperatures. In addition to the device’s technical specifications, the M39003/01-7053H provides numerous other benefits. Fulfilling the requirements of military and aerospace applications, the capacitor is able to tolerate high vibration levels and wide temperature ranges. It also has an extended shelf life, offering stable performance over long periods of time. The M39003/01-7053H tantalum capacitor is a relatively new technology developed to meet the demands of modern military and aerospace applications. With its impressive performance capabilities and impressive stability, the device is sure to become a popular choice for these types of high-end applications.
