Tantalum Capacitors
Tantalum capacitor is a type of capacitor, which has a tantalum anode and an electrolyte impregnated with an oxide cathode. Characterized by large capacitance for their size, they are widely used in electronics, from medical and military to consumer electronics. Particularly, the M39003/03-0143/TR tantalum capacitor is a standard commercial grade and mainly used in avionics and electromechanical applications.
Application Field
M39003/03-0143/TR is ideal for applications in high density modules and solution due to its small size. Commonly uses in communication systems such as in the avionics dedicated to the industrial, communication and automotive areas. It meets the requirements of most of the environmental-friendly standards such as RoHS, REACH, and in accordance with UL 94V-0 for the plastic molding compound. In addition, the capacitor is AEC-Q200 qualified.
Working Principle
The main principles of how a tantalum capacitor works can be explained as follows. Tantalum capacitors are essentially a tiny version of a typical electrochemical double-layer capacitor that uses an electrolyte as a conductor of energy between two electrical conductors, as opposed to a conventional capacitor that uses a dielectric insulator. The tantalum capacitor starts with a tantalum grain which is an oxide coated anode, when a voltage is applied to the capacitor, ions from the electrolyte are attracted to the anode which creates a layer on the surface of the grain that acts as an electrical double layer capacitor.
The electrical isolation between the grain and the electrolyte depends on the covering material, which is usually an oxide layer. The capacitor is able to store energy when a voltage is applied on it, due to the charge-loss phenomenon which occurs when the charge stored on either of the two conductors is discharged. This charge-loss phenomenon, which is also called the “charging-discharging self-capacitation”, allows capacitors to store energy for circuitry that would otherwise be difficult.
The amount of energy that a capacitor can store is directly proportional to its capacitance, which is determined by its size, shape, and the material that is used to create the dielectric. With the M39003/03-0143/TR, it has a capacitance of 4.7uf and can hold a voltage of 25V. It also has a low ESR of 7mOhms and an operating temperature range of -55℃ to 85℃.
In addition, M39003/03-0143/TR tantalum capacitor is designed with a hermetic-sealed structure, preventing it from absorbing moisture from the atmosphere and short circuiting. This greatly reduces the risk of an electrical short causing a component failure.
Conclusion
The M39003/03-0143/TR tantalum capacitor is an ideal choice for applications needing a small, yet effective, energy storage component. With a capacitance of 4.7uf and a voltage rating of 25V, it offers great performance at a reasonable cost. Its hermetic-sealed structure ensures that it is protected from damage caused by moisture in the atmosphere, while its qualification for RoHS, REACH and UL 94V-0 allows for use in most environmental-friendly applications. All in all, M39003/03-0143/TR is a reliable, cost-effective choice for many different types of applications.
