Common Mode Chokes

Common Mode Chokes (CMCs) are among the most popular components used in a wide range of electronic applications. CMCs are primarily used as power line filters, isolation cores, high frequency circuit components, and components for clock signal suppression. CMCs can generally be divided into two categories: air gap CMCs and ferrite CMCs. This article will focus on the SS21V-R400005 CMC, an air gap type CMC, and its application field and working principle. The SS21V-R400005 CMC is designed to be used in industrial, automotive, and consumer applications where high efficiency and lower power consumption are required. It is suitable for use in a wide range of voltage and current levels, including high speed circuits. It has a maximum operating temperature of 130°C. The SS21V-R400005 CMC features a low insertion loss, low ESR, and low Near-End Crosstalk (NEXT). The SS21V-R400005 CMC works by suppressing common mode noise, typically through the use of air core inductors. These inductors create a magnetic field that opposes the flow of current, and acts as a filter for high frequency signals. The reduced current and increased impedance provided by this magnetic field results in an improved signal quality.The SS21V-R400005 CMC is commonly used in the following applications:• Automotive applications including power supply noise suppression.• Industrial applications including AC line filtering, AC transformer noise suppression, and EMI/RFI suppression.• Consumer products such as electronic equipment, TVs, and DVD players.• Railway applications including noise suppression for AC and DC power systems.• Defense applications including radio communication systems.• Medical applications including power supply noise suppression and signal integrity.The SS21V-R400005 CMC is designed to be an effective filter for electromagnetic interference (EMI). It can also provide protection from voltage transients in a variety of applications. In addition, the SS21V-R400005 CMC is lightweight and has a small footprint, making it ideal for use in tight spaces.In summary, the SS21V-R400005 CMC is a type of common mode choke, an air core inductor-based device that is designed to suppress common mode noise in various electronics applications. It has a maximum temperature rating of 130°C and is suitable for use in a wide range of voltage and current levels, including high speed circuits. Common applications include automotive, industrial, consumer, railway, defense, and medical applications. The SS21V-R400005 CMC provides an effective filter for EMI and voltage transients while being highly reliable and cost effective.
