Film capacitors are a type of capacitor that uses a film as its dielectric foundation layer. This type of capacitor is usually characterized by high electrical stability and low failure rate, making them a popular choice in a wide range of applications. The R76QD0470SE00K is a film capacitor that is often used in industrial and telecom applications. In this article, we will look at the R76QD0470SE00K application field and working principle.

The Application Field of R76QD0470SE00K

The R76QD0470SE00K is a metallized polypropylene film capacitor used in several industrial and telecom applications. It has a high insulation resistance of 7500V AC, making it suitable for telecommunications, power supply, and power supply systems. It is also used in network communications and in the industrial automation markets. The R76QD0470SE00K is an ideal power capacitor for capacitive discharge welding systems and other AC systems due to its high insulation resistance.

Additionally, the R76QD0470SE00K provides high reliability in high-voltage AC environments. It also has excellent self-healing characteristics and its dielectric properties ensure high temperature and voltage stability. These properties make it ideal for use in high-performance power solutions and DC filtering solutions. The R76QD0470SE00K is also RoHS compliant, making it ideal for use in applications that require meeting specific environmental requirements.

The Working Principle of R76QD0470SE00K

The working principle of the R76QD0470SE00K is similar to other film capacitors. It has a film dielectric layer made from polypropylene. This dielectric layer is sandwiched between two metalized layers. The metalized layers are in contact with the capacitor\'s terminals and are connected to an electrode system. When exposed to an electric field, the film creates a polarized dipole which makes the capacitor absorb and then release charges.

The R76QD0470SE00K has an electrostatic leakage rate of 0.15CV/s, which is much lower than its competitors. This results in a high insulation resistance and stable capicitance over time. The capacitor also has excellent temperature coefficient resistance, allowing it to be used in high-temperature systems without degradation in performance. Additionally, the capacitor provides low loss and high ripple current capability due to the metallized polypropylene film used in its construction.

Conclusion

The R76QD0470SE00K is a popular film capacitor that is used in many industrial and telecom applications. It offers a high insulation resistance, excellent temperature coefficient resistance, low electrostatic leakage rate, and stable capacitance over time. Additionally, it is RoHS compliant and has excellent self-healing characteristics, making it the perfect choice for high-voltage AC applications, power solutions, and DC filtering solutions.
