Working Principle

HM28-32022LF common mode choke has an integrated high-speed digital signal and high-frequency transformer to effectively filter and control EMI noise. It operates on the principle of counter electromagnetic induction. The working principle of this component is described in the following steps:

• When a high-frequency current passes through the preset coil of the common-mode choke, electromagnetic induction will be generated.
• This inductance will oppose changes in the current. When a high-frequency noise voltage is generated in the device, the high-frequency current will cause a sudden change in the electromagnetic field.
• The generated voltage will be processed and utilized by using the principle of electromagnetic induction and the high-frequency noise will be absorbed by the EMI common-mode choke.
• In this way, the high-frequency noise will be filtered out and suppressed.

In short, HM28-32022LF common mode choke operates on the principle of counter electromagnetic induction. This allows it to effectively filter and suppress EMI noise, making it suitable for high-speed digital signal transmission, data control, and noise reduction applications.
