Film capacitors have wide application fields including others, processing circuit, regulating circuit, coupling, and suppressing nuclear EM interference.

Among them, the application field of 170474K400NE type film capacitor is mainly used in the AC circuit system, signal filtering, interference suppressing, pulse circuit coupling, and other parts. This type of capacitor is commonly used for AC/DC working power, pulse power, such as alarm, frequency regulating, testing equipment, and automatic equipment. Also, owing to the increasing demand of circuit miniaturization in electronic components, the frequency range and continuous power of this capacitor can be reliably worked under 6G/ 2KW for 1 Φ or 3 Φ circuit. Besides, this 170474K400NE capacitor can also work in the temperature range of -25℃ to +85℃, which makes it suitable for high frequency computer, instrument, and many other integrated circuit.

Now let’s have a look at the working principle of this type capacitor. Generally speaking, the working of a film capacitor is based upon the mutual electrostatic attraction of two segments of an electrode and a dielectric film. A dielectric film is placed between two metal plates of an electrode. One or both terminals of the capacitor are insulated by the dielectric and form a strong polar electric field. When it is applied with a voltage source, the free electrons at one electrode move, as a result, a current flows create the electrostatic charge density at the both opposite electrodes. The charge density between the two electrodes forms an electric field which is balanced by the capacitance of dielectric film. Thus, electric energy is stored in the electric field.

As to the 170474K400NE film capacitor, it comes with a wide capacity and the sustained voltage up to 1.2 times of rated voltage. As mentioned earlier, this film capacitor owns the good arc-over resistance, so it can be high safely used for filtering and blocking element in various electronics fields, AC power control circuit, high density digital switching power supply, DC motor controlling, and so on.

All in all, with the above features, 170474K400NE film capacitor is widely and safely used for high frequency circuit controlling, signal filtering, coupled circuit and high voltage rectifying circuit. On the top of that, it is looked as a great choice for high temperature application. Thanks to its compact size and outstanding performance, and it is also widely used in the wider area of electronic fields.
