Film Capacitors

Film capacitors, also known as polymer film capacitors, are classified as fixed capacitors. It is a non-polarized capacitor composed of metallized plastic film as the dielectric medium, packaged in a compact cylindrical form. Using 947D271K112AEGSN, this type of film capacitor is a part of a greater family of capacitors and can be used in various applications, from power conversion to general purpose filter applications.

Design Specifications

The 947D271K112AEGSN film capacitor is designed with a cylindrical shell, a resin-encapsulated layer, and has a lead-screw type terminal. It has a capacitance range of 0.047μF to 2.2μF with a narrow tolerance of just ±10%. It also features an operating temperature range of -40°C to +85°C, and can endure a reverse rated voltage range of up to 250V.

Application Field

Its wide range of application fields, small size, and lightweight design makes the 947D271K112AEGSN film capacitor an ideal option for various applications. Commonly, it finds use in industries such as power supplies, uninterruptible power supplies (UPS), medical and audio equipment, ground devices and automotive components for internal combustion engines and instrumentation. The capacitor is also commonly used where lightweight, compact size and low leakage are of critical importance.

Working Principle

The working principle of the 947D271K112AEGSN film capacitor is quite simple. It consists of a dielectric film sandwiched between two conductive, electrically isolated metallic plates. When voltage is applied, the device accumulates negative charge on one side and positive charge on the other. This generates an electrical field between the two plates. The electrons migrate from one plate to the other until it reaches a saturation point and the voltage is equalized. In order for the device to be effective, it must have a relatively large surface area, meaning that the capacitance of the device is rationed to it\'s surface area ratio.

Conclusion

Film capacitors are an essential component to many industries, and the 947D271K112AEGSN is just one example of this type of component. The device is a key component for many industries and offers a range of excellent design characteristics, including a narrow tolerance of ±10%, a reverse rated voltage range of up to 250V, and an operating temperature range of -40°C to +85°C. These features make the 947D271K112AEGSN film capacitor an ideal choice for many applications.
