Tantalum capacitors have become an essential component in electronic systems. This type of capacitor provides high capacitance and long life reliability, as well as low leakage and voltage temperature stability due to its use of a tantalum dielectric layer. The M39003/01-2789/HSD capacitor is a specific type of tantalum capacitor, typically used in military and aerospace applications. In this article, we will provide a detailed overview of this capacitor’s application field and its working principle.

The M39003/01-2789/HSD tantalum capacitor is commonly used in military and aerospace applications due to its long-term reliability and high level of performance. It is a radial leaded surface-mount tantalum capacitor, designed for high-temperature, low-standing-current applications. It is particularly useful in applications requiring high capacitance, long operating life, and withstanding extreme temperatures. Such applications include high-temperature radio applications, power supplies, filter networks, satellite and defense use, instrumentation, and avionics.

This type of capacitor is made from a tantalum pellet and two Mn02 electrodes. The Mn02 electrodes are plated with a mixture of silver, manganese, and cobalt. The pellets are then sealed with a layer of epoxy to keep the two electrodes in place. The capacitors can withstand temperatures up to 125°C. The Mn02 electrodes provide a low (less than 1uA) leakage current, a low ESR, and high capacitance.

The working principle of the M39003/01-2789/HSD tantalum capacitor is based on the electrochemical properties of the tantalum dielectric layer and the electrical connections between the two electrodes. In operation, the positive terminal of the device is connected to a positive voltage source, and the negative terminal of the device is connected to ground. When the voltage source is switched on, electrons will flow into the positive electrode and into the positive charged tantalum ions. The electrons are then attracted to the negative electrode and out of the tantalum dielectric layer, resulting in a build-up of charge on the capacitor plates and the production of energy.

The M39003/01-2789/HSD tantalum capacitor is a reliable, high performance component that is used widely in military and aerospace applications. Its high capacitance, long-term reliability, and ability to withstand extreme temperatures make it ideal for such conditions. Its working principle is also based on its electrochemical properties and the electrical connection between the two electrodes. Overall, this type of capacitor offers numerous advantages for a variety of applications.
