Film capacitors are electrical components that use a dielectric (insulating) film to store electrical energy. One of the most common types of film capacitors is the FCN1206A182J-H2, used across a wide range of applications. In this article, we will look at its application field, as well as its working principle.

Application Field of the FCN1206A182J-H2

The FCN1206A182J-H2 film capacitor is chiefly used as a power supply component for power supply circuits and voltage-dividing circuits. It is also used for high-voltage spark noises of around 100 V in both pulse circuits and delay circuits. Owing to its very low DC leakage current and in-rush current, this film capacitor is also used in analog circuits.

The FCN1206A182J-H2 is also employed in differential amplifier circuits and impedance deviation measurement circuits, as well as in various AC noise suppression and prevention circuits, such as AC filters and differential filters. As its capacitance value and Withstand Voltage conform to standard values, it is also employed in boards that require high capacitance.

Working Principle of the FCN1206A182J-H2

The FCN1206A182J-H2 is an electrolytic capacitor that uses a film, instead of an electrolyte, to achieve a high dielectric constant. This makes it difficult for electrons to move through the dielectric, making the capacitor a low-pass filter. This means that frequencies lower than the capacitor’s cut-off frequency will pass through unhindered, while high-frequency noise will be blocked. This reduces noise in the electrical system and increases the stability of the supply voltage.

The FCN1206A182J-H2 is a particularly high-performing type of film capacitor thanks to its metalized film dielectric, which has two layers of metal coating (Al or Zn). This increases capacitance, as well as the Withstand Voltage and Operating Temperature versus other types of film capacitors.

The FCN1206A182J-H2 is a self-healing film capacitor and its internal structure is designed to allow any short circuits or breakdowns to heal over time. This makes the device robust and reliable, ensuring an extended product life-span. Moreover, its high thermal stability and high self-healing ability make the FCN1206A182J-H2 suitable for use in high-pressure and high-temperature environments.

Conclusion

The FCN1206A182J-H2 is a reliable and high-performing film capacitor widely used in a variety of power supply and noise reduction applications. Its metalized film dielectric gives it a superior capacitance and Withstand Voltage, as well as excellent Operating Temperature and thermal resistance. Moreover, the device is self-healing, making it suitable for high-pressure and high-temperature environments.
