Tantalum Capacitors

Tantalum capacitors, commonly referred to as Tant cap or tantalum electrolytic capacitors, are capacitors that can store an electrical charge with a very low rate of leakage or even no leakage at all. They are made from a tantalum metal oxide with a relatively large capacity, which makes them very stable and reliable. Tantalum capacitors have a low ESR (Equivalent Series Resistance) and are commonly used in high-frequency and high-voltage applications.

M39003/01-2689/TR — Application Field and Working Principle

The M39003/01-2689/TR is a high-quality tantalum capacitor manufactured by Phoenix Technologies Corporation. This type of capacitor is mainly used in data and communications network systems, cellular radio networks, video, and audio recording systems, medical imaging imaging systems, consumer electronics, and military applications. It is also used in many other applications such as power supplies, consumer computing equipment, and other precision electronic systems.

The M39003/01-2689/TR is a two-part capacitor composed of a tantalum anode and a glass-sealed vitreous electrolytic (GSE) material. The two parts are connected together via a single pin connector, and the two terminals are connected to the circuit board, via soldered jump wires. This allows the capacitor to provide the necessary solid-state polarity control for the circuit.

The working principle of a tantalum capacitor is based on the electrochemical effect. When an electrical charge is applied across the two terminals of the capacitor, an electrochemical reaction occurs in which a current is created. This current allows for the transfer of charge between the two terminals.

When the capacitor is charged, the electrolyte is drawn into the anode and the oxidation process occurs, creating a layer of metal oxide at the anode surface. When the capacitor is discharged, the metal oxide is neutralized and the electrolyte is removed from the anode.

The advantages of using a tantalum capacitor include its high capacitance, high stability, low ESR, high reliability, and long life expectancy. These features make it ideal for use in many types of high-performance circuits where reliable operation and consistent performance are important.
