Tantalum Capacitors are another type of capacitor, next to ceramic and aluminum capacitors. They are used in different types of electronics, such as radios, television sets, cell phones, computers, and other connected systems. For this reason, they are also known as “solid electrolytic capacitors.”

The T97R476M035EBA is one of the numerous types and packages of tantalum capacitors available, designed to meet the highest standards of reliability. The package incorporates four capacitors mounted on a common lead frame. It offers an exceptionally low ESR and high ripple current.

Application Field

Tantalum capacitors are increasingly used in many different applications and their use is growing due to their numerous advantages over ceramic and aluminum capacitors. Their small size, high capacitance, and low ESR make them highly attractive for applications such as consumer electronics (including audio/visual equipment and gaming consoles), security systems, automotive electronics, computers, medical electronics, and renewable energy.

The T97R476M035EBA is a reliable choice for use in a wide range of higher capacitance applications, offering significant advantages over conventional capacitors. It provides a wide capacitance range of 47µF to 2200µF in a standard package size, a high ripple current capability of 1.4A, and a low ESR of 0.28 ohm.

Working Principle

Tantalum capacitors are electronic components with two conductive plates, one of which is made of Tantalum, a metal ore. The other plate is usually made of Aluminum, or Nickel. The Tantalum plate is covered with a dielectric (a non-conductive layer). Different types of dielectric materials are used, such as Tantalum Oxide, Organic Polymer, or Aluminum Oxide.

When a voltage is applied across the plates, a small current flows through the dielectric and charges the capacitor. This charge enables the capacitor to act as a voltage source when the power supply is unhooked from the circuit. The capacitor’s design and the dielectric material used determine the voltage and capacitance value. The T97R476M035EBA, for example, provides a maximum voltage rating of 35V and a capacitance range from 47µF to 2200µF.

Tantalum capacitors are also known for their high surge currents and low ESR. The surge current is the highest current that the capacitor can deliver for short-term operation, while the ESR is the equivalent series resistance (ESR) of the capacitor. The low ESR makes it more efficient for high-frequency applications, as it provides better performance than traditional aluminum capacitors.

Conclusion

Tantalum capacitors are becoming increasingly popular in many different industries due to their high capacitance, small size, and low ESR. The T97R476M035EBA is an excellent choice for applications such as consumer electronics, automotive electronics, and security systems, as it provides a wide range of capacitances from 47µF to 2200µF and a low ESR rating of 0.28 ohm.
