Common Mode Chokes

The ELF-18D850C application field and working principle is a common mode choke, also referred to as a CM choke or a common mode filter. It is a type of electrical component that is designed to limit the amount of undesirable or high-frequency noise which is generated on an electrical signal line. CM chokes utilize a pair of inductors that are configured in a way that allows the inductors to chamber and reduce the amount of high-frequency noise over a signal line, allowing for a much cleaner signal output.

A common mode choke is used to suppress high-frequency noise in signals and power lines. This high-frequency noise can be generated on signal lines due to the presence of other equipment and signals that may be causing interference. Common mode chokes can be used in many different electronic devices such as cell phones, televisions, computers, and other electronic components where high-frequency noise needs to be reduced in order to ensure a clean signal output.

The ELF-18D850C application field and working principle is a surface mounted, low-profile common mode choke that has a wide-band frequency response from 8 MHz to 2 GHz. This means that it is capable of providing high levels of noise reduction across a wide range of frequency ranges and is the perfect solution for managing high-frequency noise in signal lines and power sources. The ELF-18D850C also features a low-profile, surface mount design, meaning that it is highly compatible with most surface mount applications.

The ELF-18D850C has been designed to work with both digital and analog signals. It is capable of providing wide-band frequency response and is able to reject EMI/RFI interference. This common mode filter features low insertion loss and a high common-mode greater-than 40 dB (at 50 MHz) along with over 40 dB of common-mode rejection at 100 MHz. It is also suitable for use in signal lines where wide-band noise immunity is required.

Common mode chokes are widely used to reduce high-frequency noise in power sources and signal lines. They are also commonly used in automotive, audiovisual, telecoms, and other applications where EMI interference is present. The ELF-18D850C application field and working principle is a low-profile common mode choke that is capable of providing excellent noise reduction and wide-band frequency response with low insertion loss and a high common-mode greater-than 40 dB (at 50 MHz).
