Film Capacitors

BFC237541472 Application Field and Working Principle

Film capacitors, also known as film dielectric capacitors, plastic film capacitors, paper dielectric capacitors, are capacitors whose anode and cathode electrodes are separated by a thin layer of plastic film. Film capacitors are widely used due to their higher performance than other types of capacitors. BFC237541472 is one of the most popular film capacitors on the market. It is a surface mount mica film capacitor with a rated voltage of 250Vac and its main application fields are power supplies and AC/DC inverters.

Working Principle

Film capacitors function in an analogous manner to that of electronic components like capacitors and coils. They are typically made up of a thin film insulating material sandwiched between two voltage electrodes. When a voltage is applied across the capacitor, an electrical field is established and a charge is stored in the capacitor’s electric field. This stored electrical charge can then be released back into the circuit at a result. This back and forth cycle is termed as the capacitance effect and is the underlying principle behind the working of a film capacitor.

The film capacitor’s voltage capability is dependent on the thickness of the insulating film. Using thicker insulation films will result in higher voltages being applied to the capacitor without it being damaged. This is one of the advantages of using film capacitors in preference to other types of capacitors. The response time of the capacitor also depends on the thickness of the insulation film and the more the thickness, the faster the response time.

Applications

As mentioned, one of the main applications of the BFC237541472 is for use in power supplies. Their high voltage capability makes them ideal for this kind of application. They are also used in AC and DC inverters, which are used for converting AC power to DC power and vice versa. This kind of application requires capacitors with high voltage capabilities as well as a good response time, and the BFC237541472 is one of the few film capacitors available that can provide this type of performance.

In addition to their usage in power supplies and AC/DC inverters, film capacitors are also used in the automotive industry. This particularly involves the use of film capacitors in power train and other fuel injection systems. The BFC237541472 is also an excellent choice for these applications as its high voltage capabilities and fast response time make it perfect for the demanding requirements of these systems.

Conclusion

The BFC237541472 is a high-performance film capacitor that is capable of handling high voltages without being damaged. It is particularly ideal for use in power supplies and AC/DC inverters. It is also widely used in automotive applications, especially in power trains and fuel injection systems. The key advantages of this capacitor include its high voltage capability, fast response time, and relative low cost.
