Common Mode Chokes are components used in many technical applications across all industries. The HM67-B472LFTR13 is a particularly popular choke due to its superior performance in a variety of applications. This technical brief describes the application field and working principle of the HM67-B472LFTR13 so that users can better understand what it can do and how it works.The HM67-B472LFTR13 is a high-temperature-resistant, small-sized common mode choke that can operate over a wide frequency range and temperature range. It is a three-coil common mode choke, meaning it features three coils wound on a single core. This allows it to efficiently reject common-mode noise and provide an extremely low impedance for common-mode currents. This feature makes it ideal for many different applications.For example, the choke can be used in signal line applications to reduce the amount of common-mode noise. This type of noise can cause signal distortion, loss of information, and other problems, so it is important to reduce it as much as possible. The choke helps reduce the noise because it serves as a low-pass filter that eliminates the signal’s high frequency components. This helps prevent signal distortion and allows the signal to be accurately transmitted.The choke can also be used to reduce common mode interference in power lines. Electrical power distribution systems often suffer from problems caused by high frequency noise. This type of noise can cause electrical equipment to malfunction, resulting in a decrease in performance and even complete system failure. The choke’s ability to reject common mode interference helps to eliminate this problem and prevent power line failure.In terms of working principle, the HM67-B472LFTR13 choke works differently depending on whether it is used for AC or DC applications. For AC applications, the choke is effective in rejecting common-mode noise because the direction of the voltage across each winding is constantly changing. This helps to reduce the amount of interference by preventing the path of current from forming a complete loop.For DC applications, the choke works differently. Instead of reducing the current flow in a loop, it reduces the amount of current that can flow across the windings. This is because the choke’s internal circuit creates a magnetic field, which disrupts the electric field set up by the current. This reduces the amount of current that can flow across the windings and helps to reduce any interference.In conclusion, the HM67-B472LFTR13 is a popular common mode choke used in many technical applications. It is high temperature-resistant and has the ability to reduce common-mode noise in both AC and DC applications. This makes it a reliable and efficient solution for many different applications.
