Tantalum Capacitors

Tantalum capacitors are electrical capacitors whose anode contact material is formed from a sintered tantalum powder. These are widely used in modern electronics due to their robust construction and small form factor. They have a much higher capacity than other types of capacitors, and they are able to withstand high temperatures and higher voltage than most other capacitors.

M39003/01-8347H Application Field and Working Principle

The M39003/01-8347H is a small-sized tantalum capacitor, designed primarily for use in high temperature environments. This makes it suitable for applications such as in automotive, aerospace, and military electronics. The main advantage of this device is its small size, making it suitable for use in compact circuits. The device has an operating temperature range of -55°C to +150°C and a capacitance range of 10 µF to 6.3 µF.

The capacitance value of the M39003/01-8347H is defined by the ratio of voltage applied tocharge and the amount of electric charge stored. The amount of charge stored per unitvoltage is the capacitance. The capacitor stores electrical energy on the anode by a process called electrochemical conversion. Electrochemical conversion creates a thin layer of oxide on the anode that stores the charge, while the cathode is connected to a ground point. This structure creates a parallel plate capacitor, and when a potential is applied, charge is stored on the anode and discharged from the cathode.

The M39003/01-8347H is classified as a “chip” tantalum capacitor, meaning that the anode and cathode contacts are both connected to a single piece of metal. This allows the capacitor to be integrated into a single package, which is then soldered onto a printed circuit board. Because the capacitor is soldered onto the PCB, its value must be set correctly before use. Depending on the application, the current requirement could exceed the rated maximum current, and the voltage rating could exceed the rated maximum voltage, so careful consideration should be taken when selecting the appropriate value.

The M39003/01-8347H tantalum capacitors provide a high level of electrical and thermal performance, and their small size makes them ideal for use in a wide range of applications. Additionally, their long shelf-life and low ESR make them a cost-effective option for applications where space and power efficiency are a priority.
