FE2X47-4-2NL

Common mode chokes are a type of electronic filter specifically used to suppress EMI (electromagnetic interference) and reduce differential mode noise from signals. The FE2X47-4-2NL is one such product from Fairchild Semiconductor. It is specifically designed for low cost and high performance, making it suitable for many applications.

In general, common mode chokes work by creating a low-pass filter that blocks any high frequency noise from being transmitted. This ability to filter out unwanted signals prevents interference and crosstalk among other components in a system. As such, they are often used in medical systems, automotive products, consumer electronics, and other applications that require reliable electrical performance.

The FE2X47-4-2NL is suitable for such applications due to its low cost and high performance. It is constructed with a high-end iron core and high-performance winding wire, which makes it able to handle high current environments with minimal voltage drop. This makes it suitable for automotive, consumer, medical, and other applications where high operating temperatures, electrical noise, and high current are present. Additionally, the FE2X47-4-2NL has a wide band noise suppression capability, making it suitable for applications with high-frequency noise.

In terms of specific applications, the FE2X47-4-2NL is suitable for automotive onboard electrical systems, personal electronics, medical appliances, and consumer products. It can be used to filter out unwanted signals, such as those emitted by battery management systems, vehicle charging systems, telecommunication systems, and RFID readers. It is also used to reduce audible noise in higher frequency electrical systems, such as those used in medical devices and surgery tools.

The working principle of the FE2X47-4-2NL is similar to the other common mode chokes in that it uses a low-pass filter to block any high frequency noise from being transmitted. This filtering action helps to improve overall system performance by eliminating unwanted interference and crosstalk, as well as preventing any over/under voltage issues. The winding wire inside the choke creates an inductive element which passes signals of only certain frequencies, allowing low frequency signals to pass while blocking out high frequency signals.

In conclusion, the FE2X47-4-2NL is a high performance, low cost common mode choke from Fairchild Semiconductor. It is suitable for many applications, including automotive onboard electrical systems, personal electronics, medical appliances, and consumer products. It works by creating a low-pass filter that blocks any high frequency noise from being transmitted, helping to improve system performance by eliminating EMI and differential mode noise.
