104MPR400K Film Capacitors

Film capacitors are a type of capacitors often used in electronic circuits. The 104MPR400K series of film capacitors are some of the most popular on the market. This series are polyester film capacitors designed for low inductance and high-frequency capabilities, making them ideal for various applications.

Features

The 104MPR400K series of film capacitors are made of polyester film and use an epoxy resin as the dielectric. This makes these film capacitors highly reliable and dimensionally stable compared to other types of capacitors. They also boast low inductance and high frequency capabilities, and have a temperature range of - 55C to +125C and voltage ratings from 100VDC to 400VCD.

These type of capacitors come with a variety of features, such as:

• Low impedance and high frequency capabilities
• High corrosion resistance
• High stability over wide temperature range
• Reinforced insulation resistance
• Insulation resistance to coiling the leads
• Non-polurised

Application

Due to its features and wide temperature range, these film capacitors are widely used in all sorts of applications, such as power supplies, voltage converters, high-frequency applications, and other related applications. Its high consistency and reliability ensures even performance across all sorts of applications. Furthermore, their insulation resistance allow them to be safely used in hazardous environments.

Working Principle

A film capacitor works by storing electrical energy in the form of a static electrical field. It works in a similar fashion to other types of capacitors, such as electrolytic and ceramic capacitors. When a voltage is applied to its terminals, it creates an electrostatic field between the plates. This electrostatic field is what stores the electrical energy and creates capacitance. When the voltage is removed, the electrostatic field collapses and the capacitor releases its stored energy.

Conclusion

The 104MPR400K series of film capacitors are reliable and offer superior performance compared to other types of capacitors. They are suitable for a wide range of applications, including high-frequency applications, power supplies, and voltage converters. Their insulation resistance also makes them suitable for hazardous environments. They work by storing electrical energy in the form of an electrostatic field, which is created when a voltage is applied.
