Film Capacitors are a type of capacitor that has been around for over a century and have been successfully utilized in a huge variety of applications. One such capacitor is the FCN1206A472J, which has many applications and a unique working principle.

Overview of FCN1206A472J

The FCN1206A472J is an aluminum electrolytic SMD (Surface Mount Device) capacitor. It has an 8.6 mm long plastic case, with a diameter of 5.5 mm and a height of 4.2 mm. The capacitor is designed to withstand a maximum voltage of 630V DC. The maximum capacitance for this capacitor is 470µF, and its tolerances are +/- 20%. It also has a very low ESR (Equivalent Series Resistance) of 0.014Ω.

Applications

Primarily, the FCN1206A472J is used as an energy storage device in various electronic circuits. It can be used as a filter capacitor to suppress high-frequency noise or as a decoupling capacitor for power supply circuits. Since it has very low ESR, it is also used to regulate voltage levels in electronic systems. Other applications for this capacitor include power factor correction, motor start circuits, and DC/AC converter circuits.

Working Principle

The FCN1206A472J capacitor works similarly to other capacitors. An electric field is established between two conductive plates, one made of aluminum and the other of a conductive dielectric material such as paper or plastic. Electrical energy is stored in this electric field, and when an external voltage is applied, the capacitor allows current to pass through it. The rate at which the current passes through the capacitor is determined by the capacitance, meaning higher capacitance means more current will pass through it.

Conclusion

The FCN1206A472J is a versatile capacitor with many applications in the electronics industry. Its low ESR makes it ideal for regulating voltage levels, as well as for noise suppression and power supply decoupling. Furthermore, due to its compact size, it can be used in almost any type of electronic system. When used properly and within its specifications, the FCN1206A472J can provide reliable performance for many years.
