Tantalum Capacitors

What is a Tantalum Capacitor?

A tantalum capacitor is an electrolytic capacitor, a passive electronic component, which has a tantalum (Ta) oxide layer as its dielectric material. Tantalum capacitors are widely used in consumer electronics, computing, aerospace, and industrial applications, due to their low profile, small size, high capacitance, and low leakage current. Tantalum capacitors offer several advantages over other types of capacitors, including a high level of stability, an excellent frequency response, better power handling, lowerloss levels, and high resistance to radiation.

History of Tantalum Capacitors

The history of tantalum capacitors began in the late 1940s when engineers began experimenting with the element tantalum for use in capacitors. Due to high melting point of tantalum, engineers used it in the form of a thin wire, which acted as an electrolyte in the capacitor. This early version of tantalum capacitors eventually evolved into the modern-day devices used today.

The M39003/01-7274H Tantalum Capacitor is an abundant, robust, and reliable capacitor used for circuit protection and decoupling purposes. It has numbers of applications across industries such as aerospace, automotive, communications, consumer electronics, industrial, and military. This particular capacitor is engineered with durable and rigid epoxy-coated tantalum caps and high-reliability terminal welds. The M39003/01-7274H Tantalum Capacitor has several advantageous features such as an operational temperature range of -55°C to +85°C, an operating voltage of 4.3V and 16V, a capacitance of 5600uF and 2000uF, an ESR of 0.19 ohms and 0.06 ohms, and a tolerance of 20%.

M39003/01-7274H Application Field and Working Principle

The most common applications for M39003/01-7274H Tantalum Capacitor include bypassing, filtering, and decoupling in power-supply circuits. It is also used as an energy storage device for electronic circuits such as computers, radios, and amplifiers. The capacitor is designed with a tantalum oxide layer as its dielectric material. This layer is charged and capable of storing electric energy. When current passes through the device, a charge is applied, which results in a change in the potential difference between the electrodes. This difference in potential creates an internal electric field, which is the fundamental working principle of a capacitor. In other words, the capacitor acts as a storage unit for electric charge, with the electrodes behaving like two parallel plates, separated by a dielectric material. The stored electric charge allows the capacitor to act like a two-port device, allowing energy to flow across it in two directions.

Conclusion

Tantalum capacitors have become increasingly popular due to their low profile, high capacitance, and low leakage current. The M39003/01-7274H Tantalum Capacitor is an example of this, with applications in various sectors due to its robustness and reliability. It works by applying current to the device, which creates an internal electric field, allowing it to act like a two-port device, and store electric energy.
