Common Mode Chokes
Common mode chokes play a critical role in enhancing the performance and reliability of electronic systems by filtering out unwanted noise. CMC`s suppress the common mode interference, therefore are an essential part in power supplies, telecommunications, and many other applications.As electronic devices continue to become more sensitive and compact, the demand for common mode chokes will remain critical in ensuring compliance with EMI standards and maintaining signal integrity.
Common mode chokes consist of two or more coils wound on a single magnetic core, typically made of ferrite or laminated iron, arranged in a way to attenuate the common mode noise and allow the normal operation of the differential signals.
General Features
- Wide ranging inductance values to attenuate the common mode noise as required for wide Operating Frequency ranges.
- Ferrites Cores Mn-Zn with High Permeability, Ni-Zn in various shapes namely EE, ET, FT, UU, Toroid etc.
- Metal Powder, Amorphous & Nanocrystalline Cores in Toroid shape.
- Sectional bobbins for increased stray inductance.
- Varied isolation requirements 1500V ~ 3000V between Winding to Winding.
- Taped / Coated cores depending on the isolation Requirement.
- Triple Insulated wire ( Reinforced insulation ) if required to enhance the insulation further.
- Varnishing under Atmospheric Pressure / Vacuum.
