T86D156K020EAAS is a type of Tantalum Capacitors, which are specialized formulated capacitors in the family of electrolytic capacitors.

Background Introduction

Tantalum capacitors are electrochemical components that are used frequently in electronic circuitry. As a result of their unique construction, they have a higher conductance when compared to other capacitor technologies. They also have a much longer lifespan, due to their solid electrolyte and tantalum anode construction. Tantalum capacitors are frequently used in critical applications.

Application Field

T86D156K020EAAS are used in a wide range of applications, such as snubbers, decoupling, timing circuits, and major power supply bypassing. In most of these applications, they are used to reduce the inductance and EMI generation. They are also used in high temperature applications, such as automotive. In these high temperature applications, T86D156K020EAAS are very effective in providing higher temperature protection.

Working Principle

Tantalum capacitors consist of two electrodes, typically a anode and cathode. The electrodes are separated by a solid electrolyte, usually made of palladium, which keeps the electrodes from touching each other. Electrical charge is produced when a voltage is applied across the two electrodes. The mechanism for charge generation is called double-layer capacitance, which is formed when an electrostatic attraction occurs between the two electrodes. The resulting charge is stored on the electrodes and can be used to reduce spikes and other signal interferences.

Range of Capacitance

T86D156K020EAAS have a wide range of capacitance, which is measured by the Farad (F). This range can go from the very small values of 0.1uF to much larger values of 1F. Typical values of capacitances for T86D156K020EAAS are 1uF – 10uF. As the value of capacitance increase, the size of the capacitor also increases.

Impedance and Dissipation Factor

Two important considerations when selecting a tantalum capacitor for an application are the impedance and dissipation factor (DF). The impedance of a capacitor is the opposition it offers when subjected to changes in current. The DF indicates how much of the energy that is stored in the capacitor is lost as heat. For T86D156K020EAAS capacitors, typical impedances are in the range of 20-100 ohms, and DF values can range from 0.003 – 0.1.

Conclusion

T86D156K020EAAS are form of tantalum capacitor with many useful features. As a result, they are frequently used in high power and high temperature applications, such as snubbers, decoupling, and major power supply bypassing. The capacitance of T86D156K020EAAS range from 0.1uF to 1F, while their impedance and dissipation factor are in the range of 20-100 ohms and 0.003 – 0.1, respectively. As a result, they offer a unique solution for many electronics applications.
