Common Mode Chokes, or CM chokes, are high-frequency, low impedance components commonly used in telecommunications and electrical networks to block common mode noise. They work by creating a physical and electrical barrier between two circuits, allowing only the desired signals to pass through while filtering out unwanted noise.

A CM choke is constructed from a core of tightly wound copper wire with ferrite or ceramic materials. The windings are placed around a core and the choke is mounted across the two circuits. The sum of the inductance of each winding produces the effective inductance of the component and controls the high frequency performance.The choke is designed to attenuate common mode noise frequencies within its channel, while passing the desired signals. The number of windings and type of core material can be adjusted to create higher or lower inductance values.

Applications for CM chokes are widespread, from AC power line conditioning, EMI/EMC protection, oscilloscope probe storage, to DC-DC converters, audio amplifiers, and more. The superior signal quality and filtering of CM chokes saves time and money by avoiding costly system reworking due to noise interference.

CM chokes are available in a wide range of operating frequencies and tolerance values that cater for all types of applications. They are also highly cost-effective, allowing users to benefit from the additional performance provided by the choke without breaking the bank.

The 744861120 CM choke is a high-frequency, low DC resistance component that offers superior noise filtering and signal quality for various applications. It is designed to block common mode noise at frequencies up to 1.6GHz while passing the desired signals without attenuation.
