Tantalum capacitors have come to constitute a significant part of electronic components that are used in most modern electronic products. Generally speaking, a tantalum capacitor consists of a tantalum foil that is sandwiched between two dielectric layers, which can act either as a dielectric or a semi-conductor. The benefit of tantalum capacitors is that they can store electrical energy for a long period of time and can be used in high-reliability applications. The M39003/01-7302E is a tantalum capacitor specifically designed for high power electronic assemblies, such as in military and aerospace electronics.

The M39003/01-7302E is an extended temperature range (XTR) capacitor which performs to specification over the temperature range of -55°C to +85°C. It has a maximum voltage of 35 volts and a capacitance range of 10µF to 470µF and a capacitance tolerance of +】-10%. The M39003/01-7302E has been designed for applications that require high reliability, high temperature performance, and long service life of over 10,000 hours of operation at +125°C.

From a working principle perspective, a tantalum capacitor typically functions as follows: when a voltage is applied to the capacitor, the surface of the tantalum foil is oxidized and forms a thin, insulating layer known as the interface layer. This layer consists of two layers: an inner layer of tantalum oxide (Tox) and an outer layer of manganese oxide (Mn02). The Mn02 layer is highly resistive to electric current and acts as a dielectric in a similar manner to an insulating material. As current flows through the capacitor, the charge stored in the Mn02 layer becomes polarized, forming an internal electric field and providing a charge-storage mechanism.

The M39003/01-7302E utilizes this same principle, but the inner oxide layer is thinner to enable higher capacitance, higher reliability and better high temperature performance. The capacitor also features a wide operating temperature range, longer service life, a low ESR and low leakage. Additionally, the M39003/01-7302E has features that make it suitable for use in high voltage applications, such as its silver/copper leads which are resistant to corrosion, its double sided epoxy coating which provides high temperature and humidity protection, and its stainless steel end caps which provide additional environmental protection.

Due to its high performance and reliability, the M39003/01-7302E is suitable for a wide range of applications. It is commonly used in military and aerospace electronics, automotive power supplies, medical and industrial equipment, and other devices which require high power capabilities and long life performance. The capacitor is also commonly used in high relability applications, as its features make it suitable for use in life support systems, hazardous environment systems, and other mission critical systems.

The M39003/01-7302E is an excellent example of a high-performance tantalum capacitor that provides superior reliable performance for demanding applications. Its extended temperature range, low ESR, low leakage, and high reliability make it an ideal choice for military and aerospace applications that require long life performance as well as high power operation.
