Working Principle of HM67-B471LFTR13

Common mode choke helps in reducing the magnitude of common-mode noise at the point of origin, which is typically in the switching power supply. This choke blocks currents from reaching other parts of the circuit while allowing differential-mode noise to pass. It determines the amount of noise that appears on the line. This is because common-mode noise directly adds to the signal voltage along the line, but differential-mode noise does not.

HM67-B471LFTR13, like other common mode chokes, works on the principle of inductance. The choke works by creating a large magnetizing current and passing it through the core of the choke. This kind of current induces a magnetic flux which in turn creates a back electromotive force, effectively blocking the currents from reaching other parts. This inductance helps to reduce the amount of noise entering or leaving that part of the circuit.

Conclusion

HM67-B471LFTR13 is an excellent common mode choke that has become popular due to its performance and robustness. It is mainly used in various applications such as automotive, industrial automation, consumer electronics, and telecommunication. The working principle of this choke revolves around the creation of an inductance across the core which allows the differential-mode noise to pass while blocking the common-mode currents. It also supports a wide operating temperature range and is available in a variety of sizes and shapes. Thus, the performance and features of HM67-B471LFTR13 have quickly made it one of the most sought-after common mode chokes available in the market.
