Film Capacitors

Film capacitors are a type of capacitor with many different applications used in today\'s electronics. The SCD105K202A3Z25-F is a film capacitor manufactured by KEMET, and is designed for use in applications such as AC line filtering, lighting dimmers, and across the line starting and voltage compensation. In this article, we will discuss the application field and working principle of the SCD105K202A3Z25-F.

Applications of SCD105K202A3Z25-F

The SCD105K202A3Z25-F is suitable for use in a range of different applications, including:

• AC line-filtering (Internal or external)*
• Line voltage compensation
• Inrush current protection
• Noise reduction
• Light dimmers
• Industrial control systems
• Test and measurement equipment

* Internal or external AC line filtering requires a minimum voltage rating of 300V, so the 275VAC rating of the SCD105K202A3Z25-F may not be suitable for these applications.

Working Principle of SCD105K202A3Z25-F

The working principle of the SCD105K202A3Z25-F is based on the storage of electrical charge in a dielectric material (polypropylene in this case). The dielectric material is sandwiched between two metal plates, typically made from aluminum or zinc. The stored electrical charge produces an electric field between the two metal plates, which acts as a barrier to further current flow and allows the capacitor to store a certain amount of energy. When a voltage is applied across the metal plates, the electric field increases, storing more energy in the capacitor.

The dielectric material in the SCD105K202A3Z25-F provides a high degree of insulation from outside electrical interference, and also increases the capacitance of the device. Polypropylene used as the dielectric material also has excellent temperature stability and high dielectric strength, making it ideal for use in AC line-filtering applications as well as other power related applications that require AC-DC conversion. This in turn allows for increased power efficiency and improved signal fidelity.

The SCD105K202A3Z25-F has a maximum operating temperature of 85°C, with a maximum capacitance tolerance of ±10%. It has a maximum voltage rating of 275VAC, and a maximum capacitance of 1000µF. The device is rated for continuous operation with ripple current, and has a minimum lifetime of 20,000 hours. The device is highly resistant to shock, vibration, and humidity, and is designed to operate in a wide range of operating temperatures.

Conclusion

The SCD105K202A3Z25-F is a high quality film capacitor manufactured by KEMET. It is suitable for a variety of applications, such as AC line-filtering, lighting dimmers, and across the line starting and voltage compensation. Its working principle is based on the storage of electrical charge in a dielectric material, and it has excellent insulation properties and high dielectric strength. The device offers high power efficiency and improved signal fidelity, and is designed to operate in a wide range of conditions. The SCD105K202A3Z25-F is an ideal solution for many of today\'s electronic applications.
