Common Mode Chokes are widely used in industrial, automotive, medical and consumer applications to suppress common mode noise, which are unwanted signals on the power line transmissions or data line transmissions. The 744821120 Common Mode Choke (CMC) provides high frequency noise filtering for power lines and data lines, helping protect valuable electronics devices from noise.
A typical CMC consists of two sets of windings over a single core enclosed in a small package. One winding or set of windings filters out the common mode noise, while the other set of windings filters out the differential mode noise. The CMC is connected in series between the source and the load and typically placed in the ground loop. Both differential mode noise and common mode noise is rejected by the CMC.
The winding of the 744821120 CMC is designed to form a balanced transmission line with an acceptable common mode impedance, usually a maximum of 500 ohms. This allows the CMC to function as an impedance transformer, providing increased common mode noise rejection at higher frequencies. The windings can be placed in series or in parallel, depending on the application. By changing the number of turns in the windings and the core material, a variety of designs can be achieved.
In addition to providing high frequency noise filtering, the 744821120 CMC also provides shielding to reduce emissions. The windings and magnetic core absorb the electric and magnetic fields, preventing them from radiating around the outside of the CMC. This reduces radio frequency interference (RFI) and other forms of electromagnetic interference (EMI).
The 744821120 CMC is also designed to operate in temperatures from -40°C to +125°C, making it suitable for a wide range of applications in both industrial and automotive environments. In addition, the CMC is compliant with UL 94V-0 flammability and is lead-free compliant according to RoHS.
The 744821120 CMC is an ideal solution for minimizing common mode noise and RFI/EMI in industrial, automotive, medical and consumer applications. It provides high frequency noise filtering, shielding and high temperature operation in a compact package.
