Fixed inductors, also known as chokes, are components packaged in small cylindrical or rectangular shapes, and are mostly made of ash or steel boxes. They are widely used in filtering, energy storage, smoothing and frequency selection to filter out signal noise. The 9406R-60 application field and working principle are described in more detail below.

Application Field
The main application fields of 9406R-60 are power supply filter, TV set differential mode filter, computer EMI filter and LCD backlight filter.

Power supply filter: 9406R-60 can be used in power source filter systems to realize the comprehensive filtering of harmonic and low frequency interference (10K ~ 200Kz) generated by electronic equipment. It can effectively reduce the equipment switching interference, electric interference and vibration noise, and make the power supply clean and efficient.

TV set differential mode filter: The 9406R-60 can be used for differential mode filtration to improve the power quality of TV sets. High frequency noise will be filtered out, and the power supply quality of the TV set will be higher.
Computer EMI filter: The 9406R-60 can be used for EMI filter on the computer main board, to prevent the harmful interference to the CPU and other related parts, thus improving the stability of the computer main board.

LCD backlight filter: The 9406R-60 can be used on the lamp driver circuit of the LCD backlight. It can effectively reduce the inductive noise generated by the switching of the lamp current and make the backlight more stable.

Working Principle
The inductance of 9406R-60 is generated by the magnetic field generated when the conductor passes the current. The working principle of 9406R-60 is to connect the inductor in series with the signal frequency, so that the signal in a certain frequency band can be filtered out, with the gain of the low frequency part and the attenuation of the high frequency part. The working frequency range of 9406R-60 is 10kHz-200kHz, and the equivalent series resistance is 5mΩ.

When the working frequency is close to the resonance frequency, the inductance will change greatly. Due to the change of the inductance, the output impedance of the inductor will also change greatly, and can be used to filter out some high frequency or low frequency signals. Therefore, the 9406R-60 is not only suitable for power supply filter, TV set differential mode filter, computer EMI filter, LCD backlight filter, but also can be used in the fields of signal noise filtering, smoothing and frequency select filtering.
