Tantalum capacitors have seen growing acceptance in modern electronics, thanks to their advantages over traditional ceramic capacitors and electrolytic capacitors. The M39003/03-3085H is a tantalum capacitor manufactured by Vishay, a leader in all things capacitor. It is an hermetic surface mount device designed for use in high-reliability and high-temperature applications. In this article, we will explore the application field and working principle of the M39003/03-3085H tantalum capacitor.

The M39003/03-3085H from Vishay is a solid, round, surface-mount tantala capacitors, with a capacitance value of 330 μF. This device is available in a 7343 package and features a wide temperature range of -55°C to +125°C, low ESR, and high ripple current handling capabilities. The combination of these characteristics make the M39003/03-3085H well-suited for use in military, aerospace, and other high-reliability engineering applications. Additionally, the device is also rated for flight applications and for space flight use.

In terms of working principles, the M39003/03-3085H is a non-polar device. It functions by having two electrodes separated by a dielectric material. When voltage is applied to the device, a polarizing charge builds up on the surface of the dielectric, increasing its dielectric constant and allowing current to pass. The electrical current that passes through the capacitor is stored in the form of a charge on the plates of the capacitor. The device is able to hold a charge until the voltage is cut off, thus allowing the capacitor to “hold” a charge and serve as a storage and release device for the electrical current.

The M39003/03-3085H tantalum capacitor also features a hermetic seal, allowing it to be used in challenging, high-temperature environments. This hermetic seal ensures that the device is leak-proof and immune to dust, moisture, or other environmental contaminants. The hermetic seal, combined with the device’s conformal coating, further boosts its endurance and longevity.

Overall, the M39003/03-3085H tantalum capacitor from Vishay is a solid device designed for use in high-reliability and high-temperature applications. Its wide temperature range, hermetic seal, and conformal coating ensure that it is able to withstand extended use in a wide variety of environments. Additionally, its non-polar design allows the device to store and release electrical current, thus making it a versatile and powerful component.
