Common Mode Chokes

Common mode chokes are inductive devices designed to suppress common-mode EMI noise on signal lines. The B82799C104N1 is the latest development in common mode chokes and contributes to improved electromagnetic compatibility (EMC). As one of the leading components in high efficiency, low noise designs, the B82799C104N1 is used in a wide range of applications.

Application Field

Common mode chokes are widely used in automotive, industrial, telecommunications, medical, aerospace, and consumer electronics. The B82799C104N1 is suitable for use in many types of electronic products including sensors, power supplies, power management systems, motor drives, and power amplifiers. It is also an ideal component for RF signal interface, digital audio systems, and consumer appliances.

Working Principle

The B82799C104N1 is a state-of-the-art common mode choke that combines a differential mode inductor and a common mode inductor into one single component. The device has an very low DC resistance with high level of self-inductance. This ensures good impedance matching and maximum noise suppression. The choke also features a flat frequency response, high Q factor and wideband noise suppression capabilities.When the B82799C104N1 is connected to a circuit, it works to reduce noise and eliminate common mode EMI on the signal lines. The device works by passing a series of high-frequency currents through the inductor that match the frequencies of the EMI noise. To achieve this, the device has to be in a state of resonance, meaning it must have the right capacitance and inductance to create the desired resonance frequency. When the noise is reduced or eliminated, the signal is able to pass through with minimal loss or distortion.

Conclusion

The B82799C104N1 is a high performance common mode choke that is designed to suppress common mode EMI noise on signal lines. It has a very low DC resistance with high levels of self inductance, and its wideband noise suppression capabilities make it suitable for a wide range of applications. With its flat frequency response and high Q factor, this device is ideal for applications requiring improved EMC.
