The M39003/01-5352H Tantalum Capacitor

The M39003/01-5352H is an axial-leaded, hermetically sealed tantalum capacitor designed for military and aerospace applications. It is constructed with a porous tantalum anode and electroded with a solid manganese dioxide (MnO₂) cathode. It is also encapsulated with an epoxy encapsulating compound for added insulation and robustness. Developed by Mallory Sonalert Products, the M39003/01-5352H is known for its reliable performance even under extreme environmental pressures.

Application Fields

The M39003/01-5352H is often used as an integral part of military and aerospace systems, as it is capable of withstanding the wide range of conditions encountered in such environments. It is mainly utilized in signal and power supply line applications, and is useful for a variety of both AC and DC uses. Its temperature range of operation is -55°C to 85°C, and it can be used safely at temperatures as high as 150°C due to its superior thermal tolerance. The capacitor also offers excellent compliance to high-energy and reliability requirements, as it has a long lasting life cycle for reliable operation.Additionally, the M39003/01-5352H is an ideal solution for many demanding applications requiring reliability, such as pulse power systems, radiation hardware, and aerospace systems. Its rugged construction, hermetic seal, and high galvanic potential make it an excellent choice for applications serving military purposes. Furthermore, its use of porous tantalum as the anode affords it good thermal behaviour, making it ideal for working in applications with wide temperature ranges.

Working Principle

The M39003/01-5352H is a polarized capacitor, meaning that it should only be operated with the correct electrical polarity and voltage applied. It functions as an energy storage device by utilizing the electrostatic principle when voltage is applied to its terminals. When a positive voltage is applied to the anode, the anode\'s oxide increases in thickness due to the formation of an oxide film on its surface, and this is substantially greater than the width of the dielectric in the air gap between the anode and the cathode. This creates an insulating barrier, and thus, a separation between the anode and cathode. It should be noted, however, that the capacitor must not be operated "backwards" because the reverse polarity will cause the oxide layer to thin and create a conductive path between the anode and cathode.Moreover, the M39003/01-5352H is a non-inductive capacitor that maximizes energy storage efficiency due to its low internal inductance. It also offers a high capacitance range, with capacitances values up to 1500uF available on the market. This makes it versatile for applications where higher voltage and capacitance are needed.

Conclusion

In summary, the M39003/01-5352H is a hermetically sealed tantalum capacitor. As such, it is particularly suitable for enhancing the performance of military and aerospace systems that require reliable and high-efficiency performance. It has a high temperature tolerance, a wide capacitance range, and an excellent galvanic safety potential. Additionally, it is extremely durable and robust, making it well suited for use in demanding applications such as pulse power systems or radiation hardware.
