Power Line Filter Modules typically have to accomplish multiple tasks. Commonly, these include eliminating common-mode and differential-mode currents, and providing basic galvanic isolation. It is important to select a model that is properly suited for the intended application.

FN9246B-6-06 is a compact power line filter module that can be used in a variety of applications. This filter module is constructed from a UL94 V-0 flame-retardant material and is rated for applications up to 250V, with operating temperature range of -10°C to +80°C. It measures in at a handy 80-20mm size.

In terms of application fields, FN9246B-6-06 is suitable for telecommunications, medical instruments, audio equipment, industrial control applications where impedance and signal integrity is desirable. The filter module meets standard FCC Class B requirements. It effectively eliminates electromagnetic interference, and can even be used for data lines at 500 MHz.

As for working principle, the FN9246B-6-06 works by providing inductor coils in combination with resistors and capacitors. These components form a low pass filter which works by absorbing high frequency signals and discarding low frequency ones. In the case of FN9246B-6-06, the input is on one side and the output is on the other. The filter module consists of an input inductor together with appropriate capacitors and resistors to provide high frequency attenuation. The input inductor typically has higher inductance than the output inductor, which helps to reduce the effects of coupling between the two lines.

The filter module also features two capacitors placed between the input and output in order to block the common-mode and differential-mode signals. As a result, the electromagnetic radiation in the frequency range of the input and output lines is eliminated. Moreover, the filter module also offers galvanic isolation, allowing for the system to operate safely at mains voltages.

In summary, FN9246B-6-06 is a compact power line filter module that can be used in a variety of applications. Its multiple tasks include eliminating common-mode and differential-mode currents, and providing basic galvanic isolation. Its working principle is based on providing inductor coils in combination with resistors and capacitors, which form a low pass filter. This filter module can be used for telecommunications, medical instruments, audio equipment, industrial control applications where impedance and signal integrity is desirable.
