Applications of the PHE450MF6680JR06L2

The PHE450MF6680JR06L2 is designed to handle high voltage, high Q applications and is useful in a variety of situations. The capacitor can be used as a dc blocking capacitor in circuits where dc voltage needs to be kept away from other components. Additionally, the PHE450MF6680JR06L2 can also be used as a bypass capacitor to keep high frequency ac signals away from sensitive components. Lastly, the film capacitor can be employed to filter high frequency ac signals.

Working Principle of the PHE450MF6680JR06L2 Film Capacitor

The PHE450MF6680JR06L2 is a polyethylene-naphthalate film capacitor with an operating voltage of 450VAC and a capacitance rating of 0.68uF. The capacitor is constructed of two metalized polyethylene-naphthalate dielectric layers between which is a conductive layer. This conductive layer is formed when the two metalized layers are pressed together in such a manner that it forms multiple contact points. When an AC voltage is applied to the capacitor, the current flow is limited since the AC voltage changes polarity over time. This alternating current flow creates an electric field between the two layers, which stores energy.

When the capacitor is loaded, it acts as a low pass filter, allowing low frequency AC signals to pass through while blocking high frequency signals. This prevents damage to components due to high frequency signals, as well as helps to reduce noise. Additionally, when a DC voltage is applied to the capacitor, it acts as a blocking capacitor, preventing the DC voltage from reaching other components.

Conclusion

The PHE450MF6680JR06L2 is a versatile film capacitor that can be used in a variety of general purpose applications. It is designed to handle high voltages and frequencies, and is able to block DC voltages, filter high frequency AC signals, and by-pass low frequency signals. This makes the capacitor a useful tool in many circuits.
