The M39003/01-8370H is particularly suitable for high temperature applications due to its superior solderability and operating temperature range of −55°C to +125°C. This makes it a suitable choice for applications that require long-term reliability and high-temperature environments.

Working Principle

The M39003/01-8370H is based on the principle of storage and release of electrical energy. It is composed of a negative and positive electrode, known as the anode and the cathode, respectively. The negative electrode is made of tantalum and serves as a storage for negative charges, while the positive electrode serves as a storage for positive charges. Between the electrodes, an insulating layer is formed by an organic or inorganic electrolyte.

When a voltage is applied across the electrodes of the M39003/01-8370H, electrical current flows from the positive to the negative electrode. This causes a negative charge to be stored in the negative electrode and a positive charge to be stored in the positive electrode. As the voltage increases, more current flows and more charge is stored, causing the capacitance of the capacitor to increase. When the voltage is removed, the stored charges remain and can be released when the voltage is returned. This creates a time lag between the application of the voltage and the release of the charge. This lag time is known as the capacitance of the capacitor and it is used to store and release energy.

Conclusion

The M39003/01-8370H is a miniature, surface-mounted tantalum capacitor with excellent electrical characteristics and a high level of reliability. It is used in a variety of applications, such as digital communication products, cellphone adapters, medical instruments, power supplies, military avionics, and other high reliability applications. The M39003/01-8370H is based on the principle of storing and releasing electrical energy by storing a negative and positive charge in the negative and positive electrodes. This allows the capacitor to store and release energy with a time lag, known as the capacitance of the capacitor.
