Tantalum capacitors are electronic components that store and release electrical energy using its tantalum oxide dielectric layer as a medium. The M39003/01-7368, in particular, is a long lead version of the M39003/01-2310, an encapsulated solid tantalum capacitor developed for use in military and space applications. It has gained popularity as a reliable solution for the harsh environmental conditions that such applications require.

Features

The M39003/01-7368 is rated up to 20 volts. Its unique construction features a solid tantalum anode that is surrounded by a low-permittivity (LPE) dielectric layer. This layer increases the voltage rating of the capacitor, making it suitable for use in high voltage applications. The anode also features an internal heat dissipating inner wall, as well as an external end cap that provides space for the anode lead.

The M39003/01-7368 also has an external dielectric layer. This layer, formed from a combination of glass-filled polyethersulfone and polytetrafluoroethylene, conforms to the standard MIL-PRF-39006 and provides superior stability and robustness. It also offers superior thermal stability over other types of dielectric materials.

The M39003/01-7368 contains a manganese dioxide cathode that offers high capacitance at a wide range of temperatures. Additionally, it has a wide operating temperature range of -55 to +125°C and low ESR, making it suitable for use in automotive or industrial applications. The M39003/01-7368 has an extended lifetime and is capable of up to 2.5 million hours of operation, making it suitable for long-term storage applications.

Application field and working principle

The M39003/01-7368 is commonly used in a variety of applications, including military and space applications, automotive, and industrial applications. It is also highly suitable for use in avionics, medical imaging and telecommunication systems, as well as in high frequency circuits, DC-DC converters, and in power supply regulation and control systems.

The M39003/01-7368 works by relying on the dielectric layer, which provides electrical insulation. In this way, it is capable of storing electrical energy as electrical charge, provided by an external voltage source, in the dielectric layer. The capacitor can then be used to supply energy as it is discharged, either by a current or a voltage. This process is known as capacitance.

In practical terms, the capacitor works by transmitting and storing electrical energy. The dielectric layer works as a barrier, and the charge stored in the capacitor, the so-called capacitance, is proportional to the applied voltage. The electrical resistance of the capacitor is called the Equivalent Series Resistance (ESR). The M39003/01-7368 has a low ESR and is therefore suitable for high frequency applications.
