The Type M Nanocrystalline Common Mode Choke is designed for advanced EMI suppression applications requiring high permeability, superior conducted-noise attenuation, and stable high-frequency filtering performance.
Utilizing nanocrystalline magnetic core technology, the choke delivers significantly improved common-mode noise suppression capability compared with conventional ferrite-based solutions, especially in high-frequency and broadband EMI environments.
Its optimized magnetic structure supports efficient AC line filtering, reduced electromagnetic interference, and enhanced EMC compliance performance in industrial and high-efficiency power systems.
The Type M series is particularly suitable for applications requiring compact size, high current capability, and enhanced filtering efficiency.
Customized inductance values, current ratings, insulation structures, and installation configurations are available according to customer requirements.
