Common Mode Chokes, also known as line filters, are widely used in EMC/EMI suppression applications. Common mode choke can be used in signal lines, power supply lines, and data lines, and provide a high level of EMC/EMI protection from both conducted and radiated noise. The 750311650 is a particular type of common mode choke.

Common mode chokes are primarily used to suppress common mode EMI emissions. The basic construction of a common mode choke includes a pair of windings wound in opposite directions on the same core, usually a ferrite core. This creates an inductive circuit which provides high impedance in the common mode and low impedance in the differential mode.

The 750311650 is designed to reduce common mode noise in signal lines, power supply lines, and data lines. Its operating frequency range is 2MHz to 2GHz, which makes it ideal for suppressing emissions from broadband sources. The 750311650 is available in two sizes and three versions - OA, DSL, and TDMA. The ‘OA’ version is the most common, designed for wideband applications. The ‘DSL’ version is designed for telephone line applications. The ‘TDMA’ (Time Division Multiplied Access) version is designed for mobile communication applications.

The 750311650 has a typical inductance of 18μH at 250MHz. The signal insertion loss is 2dB at 2MHz, 1.3dB at 100MHz, and 1dB at 1GHz. Other features of the 750311650 include high common mode suppression, high insertion loss, and high return loss.

The working principle of the 750311650 is based on the interaction between two magnetic fields. Magnetic fields interact with each other, and as the two windings of the common mode choke are wound in opposite directions, the incoming magnetic field is attenuated. The level of attenuation depends on the design of the choke, as well as the frequency and amplitude of the incoming signal.

In conclusion, the 750311650 is a type of common mode choke designed for EMC/EMI suppression applications. It is mainly used for suppressing common mode EMI emissions, and its operating frequency range is 2MHz to 2GHz. The 750311650 has a typical inductance of 18μH at 250MHz and the signal insertion loss is 2dB at 2MHz, 1.3dB at 100MHz, and 1dB at 1GHz. The working principle of the 750311650 is based on the interaction between two magnetic fields.
