Tantalum capacitors are a type of specialized capacitor containing tantalum as a casing material. They provide high performance and stability in various applications, such as automotive, industrial, consumer and medical electronics. The M39003/03-2026/TR is a variant of the Tantalum capacitor that is also used due to its reliability and long-term stability.

The M39003/03-2026/TR is made of tantalum pentoxide as the anode and is configured as a surface mount device. The end on the anode is sealed in a hermetic-sealed enclosure. The cathode end is a series of termination pins along with the contact points for connecting wire leads. It has a capacitance value of 470μF, maximum leakage current of 20μA, and a working voltage of 10 volts. This Tantalum capacitor was designed to provide high performance and stability in consumer electronics, automotive, industrial, and medical applications.

Tantalum capacitors have several characteristics that make them ideal for their application fields. They possess higher and more reliable capacitance values than most other types of capacitors. They also have a low equivalent series resistance, meaning that they do not distort the signal they take in or the output wave they produce. Their very low leakage current also prevents signal degradation even in harsh environments. This makes them ideal for applications requiring frequent dynamic changes and where endurance is important.

The working principle of the M39003/03-2026/TR is simple. When a voltage is applied to the anode, a process known as reoxidation takes place which causes a layer of tantalum pentoxide to form on its surface. This layer acts as a dielectric material and creates an electrostatic field between the anode and the cathode. The resistive current flow occurs between the two terminals, creating the capacitor’s electric field. This field is used to store energy that can be released through a current in a subsequent circuit.

The M39003/03-2026/TR offers a great performance in applications such as automotive, industrial, consumer, and medical electronics. Its very low leakage current and high capacitance means it works well in dynamic and endurance-critical uses. The tantalum casing makes it perfect for harsh environments while the hermetic-sealed enclosure prevents it from damage caused by moisture. Its use as a reliable and long-term stable capacitor ensures that it will continue to be used in various applications for years to come.
