Tantalum Capacitors

Tantalum capacitors have a wide range of uses, from most consumer electronics and automotive electronics applications to energy production and aerospace applications. Due to their higher energy density than aluminum electrolytic capacitors, tantalum capacitors are well suited for power supply applications and for use in environments subject to high temperatures, shock and vibration. In addition, thanks to their low ESR and ESL characteristics, tantalum capacitors are becoming increasingly popular in clock and signal conditioning applications.

The model 199D686X06R3D1V1E3, for example, is a 7302 chip ceramic capacitor, coated with a moisture-resistant epoxy material and is ideal for high-temperature and high-voltage applications. With a temperature coefficient of +2250 ppm/°C and an operating temperature range of -55°C to +125°C, this tantalum capacitor is suitable for low-leakage and low-ESR applications.

The working principle of tantalum capacitors is based on their structure. Inside the capacitor, two separate “plates” (separated by an insulating medium called a dielectric) are sealed into a case filled with an electrolyte. When voltage is applied to the capacitor, this causes an electric field to form inside the capacitor, allowing electrons to move between the plates. The charge capacity of the capacitor is determined by the size of the plates, the distance separating them and the type of dielectric material used. As a result, the tantalum capacitor is able to store a significant amount of energy.

In addition, because of their relatively small size and relatively large capacity, tantalum capacitors are capable of delivering very high currents, making them ideal for boosting the current output of power supplies, as well as for providing the high peak currents required in some applications. The high stability, low electrical noise and low leakage of tantalum capacitors also make them particularly suitable for situations where reliable voltage is critical.

Whether in consumer electronics, automotive electronics or high-end industrial applications, the high performance of tantalum capacitors make them a critical component in a wide range of modern electronics. The model 199D686X06R3D1V1E3, is an example of the type of tantalum capacitor that can be deployed to deliver optimal performance for the desired application.
