Tantalum Capacitors are components that store electrical energy in an electrical field. The M39003/01-7258H is an example of a Tantalum Capacitor. The range of applications for Tantalum Capacitors vary from consumer electronics and automotive applications to military and aerospace applications. Each application area, however, beyond the requirement of having capacitance with low ESR, will have different demands in terms of the performance criteria expected.

The M39003/01-7258H is a hermetically sealed, case-size, molded tantalum capacitor featuring a proven solid electrolyte design with an energy density of 190J/cc. It offers extended life and reliability over an extended temperature range of -55°C to +125°C. It is designed to meet the demands of the many different environments from consumer products, automotive and mil/aero applications by providing outstanding operational stability and reliability.

The M39003/01-7258H has a capacitance range of 1 μF to 47 μF, a voltage rating of 6.3V to 25V and a Life Expectancy of 2,000 hours. Its capacitor element is constructed with two layers of formed tantalum anode foil, tantalum particles, and cathode foil. The particles sandwich the anode and cathode foils which are connected to the outer lead frames and coated with an electrolytic dielectric. The capacitor is then inserted into a molded, hermetically sealed case and assigned an identification number.

The working principle of the M39003/01-7258H relies on two electrical fields. One field is generated by a static charge, created by applying an electric current flow from the leads to the capacitor elements. This dynamic field is then stabilized by a second electrical field (Capacitance) generated between the anode and cathode in response to a DC voltage.

The working principle of the M39003/01-7258H capacitor allows it to be used in applications from mobile electronics such as cell phones and tablets to military and aerospace systems like missile interceptors and radars. Its capacitance stability over temperature and environmental conditions, as well as longevity, makes it ideal for such applications. Moreover, the hermetic seal of the molded case insulation prevents leakage and ensures safety.
