Tantalum Capacitors

Tantalum capacitors are an electrochemical type of capacitor and operate similar to a battery. Essentially, they are two electrodes with a thin insulating dielectric layer between them to create the effect of a capacitor. The capacitance is determined by the area of the electrodes, the dielectric constant of the dielectric layer, and the distance between the two electrodes. The dielectric layer is usually a material such as tantalum oxide or Polyvinylidene Fluoride (PVDF).

M39003/01-5745H Application Field and Working Principle

The M39003/01-5745H is a high-temperature, hermetically sealed semiconductor chip tantalum capacitor, designed for use in high current, low voltage, and high frequency applications. The M39003/01-5745H offers high reliability due to its construction, which uses two electrodes and a tantalum oxide dielectric layer. The two electrodes are surrounded by a sealed glass-to-metal package on one side, and a hermetic feedthrough with a plastic-to-metal seal on the other. This design ensures that the high-temperature environment will not affect the capacitor’s performance or integrity.

When operating, the M39003/01-5745H capacitor stores a charge on the two electrodes, creating a voltage between them. This voltage is equal to the dielectric constant multiplied by the distance between the two electrodes. As the capacitor is charged and discharged, the electric field between the two electrodes increases and decreases with the changing charge. On discharge, this electric field generates an electric current which flows between the two poles of the capacitor.

Since the M39003/01-5745H capacitor is a high-temperature capacitor, it can be used in many challenging environments. It is capable of withstanding temperatures of up to 105°C without compromising performance or longevity. Additionally, the M39003/01-5745H is a low-loss capacitor with extremely low ESR, making it suitable for high-frequency applications.

Typically, the M39003/01-5745H is used in automotive, military, aerospace, energy, and industrial applications. The capacitor is typically used as a pulse energy storage device, providing the instantaneous energy required for high-current and high-frequency applications. Additionally, the M39003/01-5745H is used in power supply filtering, making the voltage more stable and providing clean power to the circuit.

In conclusion, the M39003/01-5745H capacitor is a hermetically sealed, high-temperature tantalum capacitor ideal for use in a wide range of applications. It operates on the principle of two electrodes surrounded by a dielectric layer, which generates an electric field when charged and discharged. Due to its high-temperature, low ESR, and low-loss design, the M39003/01-5745H capacitor is suitable for use in many applications, including automotive, military, aerospace, energy, and industrial applications.
