Tantalum capacitors are an important part of electronic components. This article will focus on the application field and working principle of M39003/01-7348 tantalum capacitors.
Tantalum capacitors are made from pure tantalum or oxidized tantalum electrodes. Crafting such electrode from tantalum yields two types of capacitors: wet and dry. Tantalum capacitors, filled with a manganese dioxide electrolyte, boast high capacitance by volume and low equivalent series resistance (ESR). Dry tantalum capacitors, referred to as “solid” capacitors, use a different type of tantalum electrodes and a polymer type material as the electrolyte. This particular type of capacitor is also known as polymer (or tantalum-polymer) capacitor and provides high volumetric efficiency due to its low ESR.
M39003/01-7348 is a non-solid (or “wet”) tantalum capacitor developed by Vishay. It is a preferred choice of capacitors for several reasons. This particular type of capacitor is highly reliable, as it offers increased resistance to vibration and shock. Its design allows a high frequency current to pass easily and this capacitor can also be adjusted to accommodate higher voltage levels. It also features an epoxy coating that is able to protect the metal from corrosion and to provide thermal stability.
M39003/01-7348 tantalum capacitors have many applications, such as in computers, cell phones, television sets, high-voltage power supplies, and automotive electronics. Due to their high capacitance-to-volume and low ESR values, they are also suitable for switch and filter applications. As these capacitors are non-solid, they are particularly useful audio applications, given their high frequency response.
M39003/01-7348 toggle capacitors operate on electrolytic principles. The capacitor body is composed of two electrodes, one of which is the cathode. The other electrode is the anode, and between them is a layer of tantalum pentoxide, which acts as the dielectric.
The core, or anode of the capacitor is made of tantalum metal powder. The oxide of the powder is then formed on the surface of the powder through heat and an irreversible chemical change. This process is known as anodization. After the anodization is complete, a manganese electrolytic solution is spread over the cathode. This electrolyte solution serves as the dielectric.
The electrical current is introduced into the capacitor in the form of a charges, which are held in place on the anode due to the attraction of the electrical field generated by the dielectric. The capacitor will then build up a charge until it reaches its maximum limit. The capacitor will be discharged when the current is removed from the circuit.
M39003/01-7348 capacitors offer high have many advantages and have been used in many industrial and commercial applications. They boast reliable operation in a wide range of temperature and humidity ranges and their design can be adjusted to higher voltages. They also offer excellent resistance to vibration and shock as well as a high frequency response. As such, M39003/01-7348 capacitors are excellent options for reliable power supplies, computers, automotive electronics, and audio applications.
