Film capacitors, also known as plastic film capacitors, plastic film dielectric capacitors, and polymer film capacitors, are electronic components that are manufactured from polymers such as polyester, polypropylene, polycarbonate, polystyrene, polyethylene, and polyvinylidene fluoride, among others. They offer superior properties such as excellent insulation, dielectric constants, low losses, and high frequency response. In this article, we will take a look at the 168153J400F-F film capacitors and its application field and working principle.

Application Field

Film capacitors have seen an increasing demand primarily due to their wide range of applications. The 168153J400F-F film capacitors have found their way into medical equipment, telecommunications, HVAC, electric vehicle and power tools, consumer electronics, and photonics industries. Its design is ideal for applications that require high frequency response, high insulation resistance, and low losses in order to protect and maintain the performance of electrical devices.

Working Principle

168153J400F-F film capacitors utilize a thin plastic film as a dielectric material to electrically separate the two conductive plates inserted inside the capacitor. This is what gives the capacitors their excellent insulation and dielectric constants. The two conductive plates are then equally spaced at a predetermined distance and the ends are connected to two electrodes, which allows the capacitor to store electric energy.

When a voltage is applied across the two electrodes, electric current will flow towards the capacitor creating an accumulated electric charge on each plate. This accumulated electric charge produces and repulsive force, known as the counter-electrostatic force, which keeps the electric field from penetrating beyond the dielectric material. This counter-electrostatic force is directly proportional to the applied voltage and inversely proportional to the distance between the conductive plates.

When a current is passed through the capacitor, charge accumulates on the first plate and discharge on the other, creating an oscillating energy flow between the two plates, which is responsible for the capacitor’s frequency response. The 168153J400F-F film capacitors are able to offer high frequency response due to their excellent insulation and dielectric constants.

Conclusion

The 168153J400F-F film capacitors are extremely versatile components that have found use in a broad range of industries, such as medical, telecommunications, HVAC, electric vehicles, and consumer electronics. Their working principle relies on the thin plastic film as a dielectric material, where a voltage is applied across the two electrodes which creates an accumulated electric charge, producing a repulsive force that keeps the electric field from penetrating the dielectric material. Furthermore, the capacitor is able to offer high frequency response due to its excellent insulation and dielectric constants.
