Tantalum Capacitors

Tantalum capacitors, such as the M39003/01-5040/HSD, are often used in a variety of applications. These capacitors are electrolytic in nature and feature advantages over traditional paper capacitors or ceramic capacitors. They have low ESR, high capacitance relative to their size, improved temperature stability, and long life.

Application Fields

Tantalum capacitors are used in a wide variety of applications including medical, automotive, telecommunications, power supplies, military, and consumer electronics. They are often used in circuits requiring higher capacitance values, as well as in those circuits where their low ESR values are essential.Medical applications such as heart pacemakers and defibrillators often employ tantalum capacitors. Automotive applications often use them in audio systems. They are also used in various power supply applications, such as mobile phones, computers, televisions, and notebooks. Telecommunications often make use of tantalum capacitors in applications such as power stabilizers, surge protectors, and signal processing systems. In the military, they are used in military-spec electronics.

Working Principle

Tantalum capacitors feature a two-terminal design that incorporates a dielectric layer of tantalum. They are considered electrolytic capacitors, which means they use an electrolyte to store energy. The anode and cathode plates are made out of electrolytic materials, usually tantalum, nickel, or tantalum oxide. The dielectric layer is the main component of the capacitor and is responsible for storing electrical energy.When a voltage is applied across the capacitor, an electric field is created within the dielectric layer. This electric field causes charges to move across the capacitor plates, creating electric current within the capacitor. The electric current produces a counter-electromotive force, which counteracts the applied voltage. This counter-electromotive force serves to reduce further charge accumulation within the capacitor, creating a voltage leveling effect.

Conclusion

The M39003/01-5040/HSD tantalum capacitor is a type of electrolytic capacitor that is used in a wide variety of applications. These capacitors offer features such as low ESR, high capacitance relative to their size, improved temperature stability, and long life. Their two-terminal design includes a dielectric layer of tantalum oxide which serves to store electrical energy by creating a counter-electromotive force when a voltage is applied. They are found in medical, automotive, telecommunications, power supplies, military, and consumer electronics.
