Tantalum Capacitors

M39003/01-5438/HSD Application Field and Working Principle

Tantalum capacitors are used in a variety of electronic devices, from consumer electronics to military and aerospace systems. M39003/01-5438/HSD is a particular type of tantalum capacitor typically used in military and aerospace applications. It is a hermetically sealed, axial leaded, solid electrolytic capacitor with a long-term reliability rate of up to 95 percent.Tantalum capacitors are made up of two metal electrodes with a layer of tantalum pentoxide (Ta2O5) between them. When the capacitor is charged, it stores electrical energy and can then be used to release that energy when needed. The amount of electrical energy stored in a typical tantalum capacitor is relatively small; similar to the amount of energy stored in an alkaline battery. Tantalum capacitors can perform a variety of functions, depending on their structure and the type of electrolyte used. They can also be constructed in different shapes and sizes, such as axial or radial leads. In order to meet military and aerospace requirements, M39003/01-5438/HSD capacitors are designed with hermetic seals to prevent moisture and contamination from entering sensitive parts. The capacitors also feature gold-plated terminals and a molded package for durability and reliability. In terms of their working principle, M39003/01-5438/HSD tantalum capacitors operate in the same manner as any other type of capacitor. When a voltage is applied across the terminals, a current flows between them and charge is stored in the capacitor. The charge stored is proportional to the applied voltage and is held until the voltage is removed. When the voltage is removed, the charge stored in the capacitor is released. The M39003/01-5438/HSD capacitors’ reliability and longevity come from their hermetically sealed construction – with no air or gases present in the device – along with their reliability rate of up to 95 percent. The military and aerospace grade design also make them ideal components for these applications. They are also available in a wide range of voltage ratings from 1 – 100 volts, which makes them suitable for use in a variety of applications. In summary, M39003/01-5438/HSD capacitors are a type of tantalum capacitor commonly used in military and aerospace applications because of their high level of reliability. They are a hermetically sealed, axial leaded, solid electrolytic capacitor and are able to store electrical energy, which can then be used to release that energy when required. The capacitors feature gold-plated terminals and a molded package for added durability and reliability. They are available in a wide range of voltage ratings from 1 – 100 volts, making them suitable for a variety of applications.
