Film capacitors are special types of capacitors that use thin plastic or paper sheets as a dielectric. The R75QR41504000J capacitor is one of the most popular types of film capacitors available on the market. It has a high operating temperature, high insulation resistance, and long lifetime. It is also highly reliable and cost-effective.

The R75QR41504000J is primarily used in power factor correction applications, where it is used to improve the power factor of an electrical system. The capacitor helps to reduce the total amount of energy that is consumed, thereby reducing the overall power costs. The capacitor is also recommended for use in noise suppression and other applications where high under-voltage protection is needed.

The R75QR41504000J capacitor is a polypropylene dielectric film capacitor with a lead-free tin-plating. It has a temperature coefficient of between -40°C to +105°C, offering high reliability and making it suitable for industrial applications. The R75QR41504000J capacitor has a capacitance of 44 μF (microfarads) and a rated voltage of 400V. It also has a low ESR (equivalent series resistance) and low ESL (equivalent series inductance) that make it suitable for high-frequency applications.

The working principle of the R75QR41504000J capacitor is that when AC power is supplied to it, electrical energy is stored in the capacitor and then released in the form of electrical current when there is an interruption in the power supply. This principle is analogous to that of an electrochemical cell. The capacitor stores electrical charges, and when the current is interrupted, it releases them in the form of electrical current. The capacitor works by creating a potential difference between the two terminals by storing electrical energy.

In order to maximize the performance of the R75QR41504000J capacitor, it should be properly sized to the application. The capacitance should be selected based on the maximum peak current, the operating temperature, and the frequency of the power supply. It is important to ensure that the operating temperature is within the manufacturer specified temperature range.

In conclusion, the R75QR41504000J capacitor is a highly reliable and cost-effective film capacitor that can be used for a variety of applications. It is ideal for power factor correction applications, noise suppression and other applications where high under-voltage protection is needed. The capacitor has a high operating temperature and high insulation resistance, making it suitable for industrial applications. It also has a low ESR and Low ESL making it suitable for high-frequency applications.
