As more electronic components are applied to automobiles, most signals are transmitted via LAN cables connecting these ECUs. To combat noise and make components suitable for this kind of environment, noise suppression has become crucial for safety reasons. Common-mode chokes are frequently used to suppress electromagnetic compatibility (EMC) and increase system reliability. The SMD common mode filter MM series utilize the NiZn core and can be used to filter common-mode noise across a broad range of frequencies and can provide low DC resistance and higher current-carrying capacity. Common-mode chokes are not only available for automotive applications but also for other general industrial applications that require higher quality/characteristics. The whole series is RoHs, REACH compliance, and halogen-free.
Function of common mode choke
Unshielded electronics, inverters, or other unwanted signals often result in common-mode noise current, and a common-mode choke is usually the best choice to filter/suppress these unwanted noises in electrical circuits to avoid interference problems. The common-mode choke works like a filter in the circuit and has two windings with a 1:1 turn ratio and can work in both normal and differential modes. As a common mode, the current will flow through the two windings in the same direction, which means the magnetic flux will boost each other, generating inductance to impede common-mode current. On the other hand, in differential mode, the current travels from one line from the source to the load and returns in the opposite direction as the complete circuit. The magnetic flux is canceled, and the current can pass directly.
Features
- Effective in high frequency noise suppression.
- Without degrading the signal.
- Suppress the common mode noise on electronics products
- Excellent common mode impedance at high frequency to suppress the noise.
