Film capacitors are widely used in today’s electronic devices, such as cell phones, TVs, computers, and more, due to their excellent electrical properties and reliability. The SFA24T6K219B-F is a film capacitor specifically designed for AC applications. This article covers the application field and the working principles of the SFA24T6K219B-F.

Application Field

The SFA24T6K219B-F is designed to meet the high AC demands of power factor correction and other AC-related applications. It is ideal for use in AC filters, peak current circuits, lighting ballasts, and EMI applications where low ESL, low ESR, parasitic inductance, and clean dampening are necessary. It can also be used in other places that require voltage protection and voltage-dependent control circuits. Furthermore, this capacitor is specifically designed for use in harsh environments and is equipped with an automatic build-up process.

Working Principle

The SFA24T6K219B-F is based on a non-metallic, metallized polypropylene film, which has good electrical behavior and excellent mechanical properties. The film is then rolled and welded into a cylinder and enclosed into an aluminum foil casing. This structure provides high self-healing capability and good resistance to heat, electrical, and chemical contamination. This capacitance is designed for active power factor correction, peak current smoothing, and other applications where a low-ESR film capacitor is needed. It provides high current density due to its low ESR, wide capacitance range, and high self-healing capability, even in hot or humid environments. The SFA24T6K219B-F also provides excellent damping performance over a wide frequency range, maximizing protection from AC spikes and transients.

Conclusion

The SFA24T6K219B-F is a film capacitor specifically designed for AC applications. Its excellent electrical properties and reliability make it ideal for applications such as power factor correction and peak current smoothing. It has high current density due to its low ESR and wide capacitance range, and its wide frequency response and self-healing capability provide great protection against spikes and transients.
