Film capacitors are important components in electronic circuits due to their ability to store energy. They are commonly used in many fields such as motor circuits, power electronics and measurement circuits. PHE450PB5100JR06 is a film capacitor produced by a certain electronic components manufacturer. This article will explain its application field and working principle.

The PHE450PB5100JR06 is a polypropylene film capacitor with a plastic case. It has rated capacitance of 450pF and tolerance of ±5% . The working voltage is 100V and the dimensions are 3.2mm x 6.8mm. It is commonly used in signal circuits, measuring circuits, power regulator circuits and switching power supplies to reduce signal interference and compensation. This capacitor also has excellent frequency characteristics and its self-resonant frequency is as high as 8.2MHz.

Because of its small size, the PHE450PB5100JR06 is widely used in electronic equipment with high space constraints, such as electronic instruments and remote control. Also, due to its superior frequency characteristics, this film capacitor excels in noise suppression, particularly in low frequency interference. This makes it widely used in circuits where noise signals occur frequently.

The working principle of the PHE450PB5100JR06 is based on the dielectric polarization of insulators. A two-layered dielectric is arranged between two metal layers, creating a capacitor configuration. This two-layered dielectric is made of a film substrate material, typically a high-grade Polypropylene, sandwiched between two metal layers. When an AC signal is applied, the two metal layers will attract each other, creating an electric field between them. This electric field will cause the dielectric material to polarize, allowing it to store electrostatic energy.

The capacitance of the PHE450PB5100JR06 film capacitor is mainly determined by its physical parameters, including the area of the electrodes, the thickness of the dielectric layer and relative permittivity of the dielectric.

In conclusion, PHE450PB5100JR06 is a polypropylene film capacitor with a rated capacitance of 450pF. It is mainly used in signal circuits, measuring circuits, power regulator circuits and switching power supplies. Its working principle is based on the dielectric polarization of insulators, and its capacitance is mainly determined by the physical parameters of the film capacitor.
