Film Capacitors – CB042K0103K – Application Field and Working Principle

Film capacitors are the most common Passive Electronic Components used to store electrical charges, denoted as CB042K0103K. They are used to regulate the amount of electric current either by using them in a circuit directly or by inserting them between storage nodes. It is one of the most prevalent components used in applications of both commercial and industrial sectors.

In many industries, such as communications technology and automation engineering, film capacitors are used in combination with other components as part of a power supply system or as a part of a circuit to regulate voltage and current. The two main factors governing the selection of capacitors are application field and operating principle. Depending on how the capacitor is to be used in the system, these characteristics must be taken into consideration while choosing the appropriate type.

Application Field

The CB042K0103K film capacitors can be used in many applications, due to its versatile characteristics. As it has a low temperature coefficient, it is very suitable to work on higher temperature levels than other types of capacitors. This type of capacitor provides a wide heat range and high stability, which helps it to be used in automotive applications.

Furthermore, due to its high cycle life (at least 30,000 operating cycles), it is ideal for usage in electric and electronic equipment, such as in electric motors, sound systems, telecommunication and laboratory products. It is also commonly used in industrial sectors, as it is highly effective in controlling and regulating power.

Working Principle

The CB042K0103K film capacitors works on the principle of electrostatic induction. When a metal plate is electrically charged, the electrons on the plate will accumulate around the outer edges, and will form a "shell", thus creating a "charge" around the surrounding edges. These charged edges draw in the electrons from the surrounding dielectric material, and once this charge is complete, a current begins to flow. This current is what creates the capacitance which allows the capacitor to store an electrical charge.

The CB042K0103K film capacitors also have a very low leakage current, meaning that current will not flow through the capacitor unless the voltage is present. This characteristic helps to maintain the capacitance of the capacitor over a long period of time. This makes the CB042K0103K a very reliable capacitor, as its characteristics will not deteriorate over time.

This type of capacitor also has a very low equivalent series resistance (ESR), which helps in efficient heat dissipation. This further stabilises the capacitor and makes it a very efficient component for controlling and regulating power.

Conclusion

Overall, the CB042K0103K film capacitors are a very reliable and effective passive electronic component. It can be used in both commercial and industrial sectors, due to its versatile applications and its robust characteristics. This type of capacitor is best suited for applications which require high temperature operations, as it has a low temperature coefficient and its characteristics will remain stable over a prolonged usage.
