Film capacitors, also known as plastic-film capacitor, are non-polarized capacitors that use a plastic film as the dielectric. They have increased reliability and stability compared to other types of capacitors and are widely used in power supplies, frequency filtering, automatic control circuits, signal coupling and in other fields.

The SFA66T8K475B-F is a Film Capacitor made by Samsung. It has a 6.3V working voltage, a 0.22uF nominal capacitance, and a 2.5A rated current. It can be used in applications ranging from high frequency and transient suppression to motor drive communications.

The SFA66T8K475B-F is a dielectric film capacitor that has a high insulation resistance and stable temperature characteristics. The lead wire is made from a special thermoplastic material, providing high insulation resistance, outstanding solderability and excellent high-temperature stability. The capacitor is built in an insulated circular housing made from thermoplastic that protects the capacitor from humidity, air, and dust.

The working principle of the SFA66T8K475B-F is relatively simple. When an AC voltage applied across a capacitor, a current will start to flow that charges up the capacitor. This creates a counter emf, High Voltage Capacitors which opposes the applied voltage and resists the current flow, resulting in a phase shift between the applied voltage and current, and a decrease in current, while maintaining a constant voltage. This decreases the power applied to the capacitor, resulting in a decrease in voltage. This circuit limits the amount of ripple that is sent through the capacitor.

The SFA66T8K475B-F is a reliable and cost-effective Film Capacitor used in a variety of applications. It is suitable for frequency filtering, AC motor drive communications, transient suppression, surge protection circuits and more. Its high insulation resistance and stable temperature characteristics make it a great choice for environments subject to both high heat and cold temperatures.
