JS181126-AA Application Field and Working Principle

Film capacitors, or film dielectric capacitors, are components that have a plastic film as the electrical dielectric material and two or more metallic plates to act as electrodes. Film capacitors are quite versatile components, and there are several types, each with unique advantages and limitations. The JS181126-AA type is a metalized film capacitor featuring a flat design, low profile and excellent performance characteristics. This article explores its application field and working principle.

JS181126-AA Application Field

The JS181126-AA is a non-inductive, impedance compensation capacitor constructed with a metalized polyester film dielectric. Its numerous features have made it an ideal choice for various applications.The JS181126-AA is often used in various types of power supplies, including rectifiers and inverters, where its three-dimensional shape is particularly useful. Its low profile, low inductance, low capacitance and high reliability are also beneficial in large-scale computer, monitor and server power supply.The component is also highly sought-after in automotive and aviation electronics due to its excellent performance characteristics and stability under vibration and thermal shock. In particular, its self-healing, anti-surge and high dielectric strength properties make it an ideal choice for automobile audio, electronic fuel injection and electronic control systems.Film capacitors are also used often in EMI/RFI filtering circuits since they are able to accept higher ripple currents than other capacitor technologies. The JS181126-AA combines these features with low equivalent series resistance and very low reactance, making it highly suitable for high-frequency noise filtering on electronic instrumentation, wall electronic devices and communication equipment.

JS181126-AA Working Principle

The JS181126-AA is a non-polarized capacitor constructed with a metalized polyester film as the dielectric. It consists of two or more metallic plates separated by the film, and the capacity is determined by the area of the plates, the thickness of the dielectric and the distance between the plates.When an electrical current is applied, an electrostatic field is generated in the space between the two plates. This field is kept constant by the electrodes, and a certain amount of electrical energy is stored in the form of electrostatic fields. The capacitance is determined by the size of the surface area, the distance between the plates and the quality of the dielectric.The JS181126-AA offers a number of additional benefits. Its flat structure with a low profile typically generates lower inductance than other capacitor types, in addition to having a high self-healing function, high dielectric strength and anti-surge capability. Moreover, it has very little noise, can handle high ripple currents and is able to operate over a wide temperature range.

Conclusion

The JS181126-AA is a metalized film capacitor that offers a unique combination of flat structure, low profile, low inductance, low capacitance and excellent performance characteristics. It is suitable for various types of power supplies, automotive and aviation electronics, filtering circuits and more. Its features make it an ideal choice for electronic instrumentation, wall electronic devices, communication systems and other types of applications. Its working principle is based on electrostatic fields, and its self-healing, anti-surge, high dielectric strength and low noise properties make it especially useful in mission-critical applications.
