Tantalum capacitors are valued for their large capacitance and small size. The M39003/09-4051 designed by Vishay is a surface-mount, hermetic, tantalum capacitor featuring reliable performance and small size. This capacitor is suitable for a wide range of applications and is offered with extended temperature range. In this article, we are going to discuss the application field and working principle of the M39003/09-4051.

The M39003/09-4051 is suitable for a wide range of applications, including military, medical, industrial, and commercial. It is designed to meet the requirements for professional electronics, such as aircraft avionics, medical devices, and communications equipment. The M39003/09-4051 is designed for high temperature and high current operation, offering reliable results even under severe conditions. This capacitors is also vibration resistant, making it suitable for applications where vibration can occur.

When it comes to the working principle, the M39003/09-4051 is based on the traditional tantalum capacitor. Tantalum capacitors use a tantalum anode and a solid manganese dioxide cathode in a sandwich structure. The Tantalum anode is made of a tantalum pellet that is surrounded by an oxide film, which serves as the dielectric. The anode and cathode are separated by a porous material, and the anode is held in place by a frame. When voltage is applied to the anode, the anode releases electrons, which are then collected by the cathode and stored in the capacitor. This process is known as charging, and it is repeated over and over again as long as voltage is applied across the electrodes.

In the M39003/09-4051, a gold-plated anode provides better corrosion resistance and high reliability. The anode-cathode gap is also designed to be extremely narrow to minimize the ESR (Effective Series Resistance). This results in a better surge capability, higher reliability, and better performance over a temperature range of -55°C to +125°C.

The M39003/09-4051 also features an advanced hermetic seal, which ensures that there is no air or oxygen within the capacitor, and that the dielectric won\'t degrade due to air or moisture. This hermetic seal also protects the capacitor from environmental influences, such as shock and vibration.

The M39003/09-4051 offers reliable performance and small size, making it suitable for a variety of applications. It is designed for high temperature and high current operation, making it suitable for applications where vibration can occur. Its gold-plated anode and hermetic seal ensures that the capacitor will be reliable in a wide range of environments and temperatures. Furthermore, its narrow gap between the anode and cathode reduces the ESR for better surge capability, higher reliability, and better performance.
