Tantalum Capacitors

Tantalum capacitors are electrical components that store electrical energy and are usually made from the element tantalum, hence the name. By utilizing the properties of the tantalum element, high capacitances, automotive grade reliability, and very low leakage are achieved. The T491D107M016AG is a tantalum capacitor with particular characteristics and uses.

Application Field

The T491D107M016AG is a surface-mount device with an extended temperature range of -55°C to +125°C. It is designed to provide reliable performance in the harshest automotive environments. As a result, it is suitable for a wide range of applications, including engine control, battery management systems, and drive train systems. Other areas it is suitable for include downhole instrumentation, HVAC systems, consumer appliances, medical equipment, and automotive infotainment systems.

Working Principle

A tantalum capacitor uses electro-chemical processes to store and release electrical energy. The capacitor has two conductive electrodes, referred to as anode and cathode, with a tantalum dioxide layer separating them. An insulator (dielectric) layer is then placed between the electrodes to insulate them from each other. When electrical energy is applied to the anode and cathode, a capacitance or charge is formed. When the opposite electrical charge is applied to the capacitor, it releases the stored energy. The capacitance of the T491D107M016AG is 0.015 microfarads (uF) with a rated voltage of 10 volts. Its high Q-factor and good self-healing properties assure low ESR and no permanent loss. The device also offers long service life and surpasses automotive testing requirements.

Summary

The T491D107M016AG is a tantalum capacitor designed for demanding automotive applications. It offers high capacitances, automotive grade reliability, and very low leakage, making it suitable for a variety of applications such as engine control, battery management systems, HVAC systems, consumer appliances, and medical equipment. By utilizing the properties of the tantalum element, the capacitor is also able to offer a capacitance of 0.015 uF, rated voltage of 10 volts, long service life, and high Q-factor and good self-healing properties.
