Common Mode Chokes have gained active application in industrial fields, more and more devices are turning to this kind of filter to get the electromagnetic compatibility (EMC). ELF-18D419 from Shin-Etsu Electronic Co., LTD., is a commonly used common mode choke filter.

ELF-18D419 is based on a special high-frequency and high-efficiency magnetic material with a small volume but a high inductance. With this structure, it’s able to successfully suppress common-mode noise at gigahertz or higher frequency ranges.

ELF-18D419’s application field is very broad. First of all, it can be applied in a variety of instruments and meters which are popular in industrial control, medical and measuring areas, such as digital disk writers and readers, analog/digital storage oscilloscopes, X ray tube excitation power supplies, CATV waveform detector and many other measurement meters.

It is also used in the field of communications. To name some of them: cell phones, cordless phones, digital broadcast receivers, Ethernet and other local area networks, and microwave. ELF-18D419 also works in a variety of industrial computing and information systems. Examples are the production of industrial automation systems, counter and measuring instruments, PLC controllers, motor controls, and other industrial control systems.

ELF-18D419 features a low-noise, low-distortion, and can eliminate common-mode noises at its working frequency. Its common-mode inductance of 200uH can also effectively attenuate the noise from cables.

In terms of ELF-18D419’s working principle, it’s based on the alternative current of L and C components which work as a band-pass filter and limit the transmission of noise signals. The common-mode choke can filter out the common-mode noises rapidly and accurately in a wide frequency range. Its low leakage inductance also effectively reduce the noises on the output signal.

ELF-18D419 is a trusted component from Shin-Etsu, and thisCommon Mode Choke is setting the standard for the best EMC performance in the industrial market today. With its broad application fields, high efficiency in eliminating noises and high reliability, it’s no surprise that ELF-18D419 is a preferred choice in the market.
