M39003/03-0255

Tantalum capacitors are a type of electrolytic capacitor. They have a larger capacitance per volume than other types of capacitors, making them useful in compact electronic equipment. The M39003/03-0255 is an extended temperature range, solid electrolytic capacitor. This type of capacitor is used to store and provide energy when electrons move through it.

The M39003/03-0255 features a ceramic core with a liquid tantalum electrolyte, giving it high performance and stability in extreme environmental conditions. The capacitor has a capacitance value of 68μF and a voltage rating of 25V. It is designed to operate in a temperature range of -55°C ~ 125°C with low ESR, giving it a high level of reliability over a range of environments.

The M39003/03-0255 is used in applications where reliability and stability are key factors. It is often used in military, aerospace, and medical devices, due to its ability to withstand high temperatures and vibrations. It is also suitable for high-reliability automotive applications, where it is used to provide sharp pulse current and pulse spike protection.

The working principle of the M39003/03-0255 is based on the concept of electrochemical capacitance. When voltage is applied across the capacitor, a double layer of charge forms at the electrode-electrolyte interface. This is known as the pseudo-capacitance effect, and is responsible for the capacitor’s high capacitance value. The electrolyte also acts as an insulator, preventing current from flowing through the capacitor.

The capacitor is capable of providing both high capacitance and high voltage ratings, due to its double-layer structure and design. The electrolyte also acts as a barrier to any short circuits which may form, thereby ensuring the capacitor’s reliability and stability. The ceramic core and liquid electrolyte arrangement also makes the capacitor very temperature resistant.

Overall, the M39003/03-0255 is a reliable and robust capacitor designed for use in extreme environments. Its high-voltage, high-capacitance performance makes it a popular choice for military, aerospace, and medical applications, as well as automotive and other industrial applications where reliability and stability are essential.
