Toroidal core common mode choke


A specially designed filter whose main function is to filter out electromagnetic interference signals. The main product features are as follows:

  1. High common mode impedance: CMC choke inductor has a high common mode impedance, which can effectively suppress common mode noise.
  2. Low differential mode impedance: Conversely to the common mode impedance, it has a low differential mode impedance, which means it does not interfere with normal differential signal transmission.
  3. Electromagnetic interference suppression: In computer-related or electronic products, such as switch power supplies and board card designs, CMC choke inductor is used to filter out common mode electromagnetic interference signals and prevent electromagnetic waves from radiating outwards.
  4. Filtering function: CMC choke inductor achieves efficient electromagnetic interference filtering through various winding methods.

Overall, CMC choke is a powerful tool designed to protect electronic devices from the effects of electromagnetic interference and ensure accurate and stable data transmission.
