Film capacitors are high-performance capacitors made from dielectric film materials and metal foil electrodes, and represent some of the most stable capacitors available for a wide range of applications. 474MMR250K is a table model film capacitor with a rating of MKP474MMR250K. These capacitors are used for a number of electrical applications in the industrial, military, and communications fields, and offer some of the highest quality performance when used in such critically demanding environments.

The 474MMR250K capacitor is a single-phase capacitor that operates at a frequency of 455 kHz. It is composed of a dielectric material consisting of a polyester film that is wound in the form of an electrolytic capacitor. This material provides high capacitance, high voltage stability and low noise characteristics. The capacitor also has an effective capacitance rating of 474 pF and a rated capacitance of 250 KVAR.

The capacitor is designed to provide high levels of performance and reliability when used in a variety of applications, such as:

• Power supplies – used as an energy storage device for voltage-regulating devices.
• Voltage transmission – used for voltage resistance in DC and AC circuits.
• High voltage switching – used for the protection of electronic components from voltage surge, over-voltage and transients.
• Power factor correction – used in power factor correction circuits to reduce reactive power.
• Audio and broadcasting systems – used to reduce noise and improve signal quality.
• Voltage-sensing relays – used as a voltage detector for DC and AC circuits.

In addition to its various uses, the 474MMR250K capacitor offers several benefits over other capacitors, such as:

• High stability – The polyester film used in the construction of the capacitor provides excellent voltage stability, reducing the amount of voltage fluctuation from switching and other transient sources.
• High capacitance – The capacitor has an effective capacitance rating of 474 pF, which is significantly higher than other available commercial capacitors.
• Low dielectric absorption – The capacitor exhibits lower dielectric absorption than other dielectric films, and is suitable for use in applications with high power levels.
• High voltage dissipation – The capacitor is capable of dissipating high voltage levels, making it ideal for use in high power and/or high frequency applications.
• Power factor correction – The capacitor has a high levels of power factor correction, providing improved performance in high demand applications.

The working principle of the 474MMR250K capacitor is relatively straightforward. In its simplest form, the capacitor consists of two metal plates, separated by a dielectric material. When a voltage is applied across these two plates, a current flows, resulting in an electrical charge on the plates. This charge is stored in the capacitor and, when the voltage is removed, it will remain there until it is discharged, either through a circuit or by the capacitor itself. This is the basic principle behind all capacitors, and is the principle behind the 474MMR250K capacitor.

The 474MMR250K film capacitor is one of the most popular capacitors used in the industrial, military, and communications fields. It offers excellent performance and reliability in a wide range of applications, such as power supplies, voltage transmission, power factor correction, audio and broadcasting systems, and voltage sensing relays.
