Film Capacitors

Film capacitors, or plastic film capacitors, are electrical components that incorporate a thin plastic film as the dielectric or insulating medium. Film capacitors are mostly used as bypass, blocking, coupling and decoupling capacitors. They are also used in power supplies, filters, and timing circuits. The FCP1206C393G-H3 is a film capacitor with a ceramic rod core, and it is used in a wide range of applications.

Application Field

The FCP1206C393G-H3 is mainly used for high-frequency filtering, decoupling and tuning, as well as motor start-up, acceleration and control, frequency conversion, control and protection circuits, differential counter balance and clamping protection. It is suitable for various onboard and peripheral electronics such as computers, automobiles, communications and consumer electronics, as well as low-power power supplies, AC and DC motors, solenoids and transformers.

Working Principle

The FCP1206C393G-H3 film capacitor consists of two electrodes surrounded by several layers of plastic film. The plastic film acts as the dielectric, or insulating medium, between the electrodes. The electrodes are connected to the external circuit, and when voltage is applied to them, electric charge accumulates at the electrodes. This causes an electric field to form in the dielectric, resulting in an accumulation of electric charge.

The ceramic rod core acts as a barrier between the plastic film and the electrodes, which protects them from damage. The ceramic rod core also allows for a higher capacitance, since it provides a larger dielectric surface area. The capacitance of the FCP1206C393G-H3 is specified at 0.39uF. This is more than double the 0.15uF of the same size FCP1206 capacitor without the ceramic rod core.

The FCP1206C393G-H3 is designed to operate within a temperature range of -55℃ to +105℃, with a rated voltage of 250V. It has a rated leakage current of 0.25μA, which is much lower than other film capacitors. This allows for a longer lifetime and more reliable operation. The FCP1206C393G-H3 has a high insulation resistance of 500MΩ, which is important for protection against electrical shock. The FCP1206C393G-H3 is also RoHS compliant, making it safe to use in a variety of applications.

Conclusion

The FCP1206C393G-H3 is a very versatile film capacitor that is suitable for a wide range of applications, such as high-frequency filtering, decoupling and tuning, motor start-up, acceleration and control, frequency conversion, control and protection circuits, differential counter balance, and clamping protection. Its ceramic rod core allows for a higher capacitance and better protection, while its low leakage current allows for a longer lifetime and more reliable operation. The FCP1206C393G-H3 is also RoHS compliant, making it an ideal choice for a variety of electronics and power supply applications.
