Introduction to Tantalum Capacitors

Tantalum capacitors are one of the most versatile types of passive components found in the electronics market. They are widely used in consumer electronics, automotive, military, medical, and aviation applications. As a capacitor, their primary job is to store electrical energy and then release it at a later time. They are perfect for applications where high reliability and long life is critical as they are highly resistant to shock and vibration, and are extremely stable over time and temperature.

T86D686K010ESAL Application Field and Working Principle

The T86D686K010ESAL is a metal-oxide, manganese-dioxide, tantalum capacitor manufactured by Kemet. It is designed for use in harsh environments that require high reliability. It offers high capacitance, low equivalent series resistance, and a long lifetime due to the metallized construction.

The working principle of the T86D686K010ESAL is similar to other types of capacitors in that it stores electrical charge. However, it differs from other types of capacitors because it utilizes the insulating properties of an oxide material to store the charge. This oxide material is usually built onto the surface of a dielectric. The dielectric is then layered with a thin conductive oxide material. This conductive oxide helps keep the surface charges on either side of the capacitor from neutralizing each other. The capacitance of the device is determined by the area of the capacitor and the dielectric constant.

The T86D686K010ESAL are mainly used for decoupling applications in harsh, high-temperature environments. These capacitors are often used in automotive applications where reliable operation in high temperature is required, such as navigation systems, engine control unit, and headlights. They are also commonly used in other applications such as mobile phone chargers and power management systems.

The T86D686K010ESAL can operate from -55°C to +105°C with a maximum ripple current rating of 4.5A. The maximum volumetric efficiency rating is 7.3V/mm and can handle a peak pulse current of 78A. The capacitance of the device ranges from 0.10µF to 10.0µF and its rated ESR is 0.019Ω.

Conclusion

The T86D686K010ESAL is a reliable and robust tantalum capacitor used in a wide range of harsh environment applications. It offers high capacitance, low ESR, and a long lifetime due to its metallized construction. It’s perfect for decoupling applications in automotive, military, aviation, and consumer electronics applications.
