Common Mode Chokes

Block High Frequency Noise with Our Common Mode Choke Series

A common mode choke (CMM) serves as an efficient way to filter in-phase supply lines, enabling equipment to meet strict electrical radiation specifications. It helps filter and block high-frequency, common mode current noise in the supply lines. High frequency noise can potentially damage other electrical components or devices in your system if left unfiltered.

Amgis offers a variety of standard high efficiency common mode chokes. If necessary, our team of engineers can design a custom common mode choke to fit your specific requirements.

CA Series Common Mode Toroidal Chokes

CLJ-2 Series – Miniature SMD Common Mode Double Chokes

This common mode choke line is designed for SMD (surface mount) applications and are packaged for pick and place compatibility. Our team has more than 20 years of manufacturing experience so your SMD products provide consistent and reliable coplanarity.

We offer many standard options as direct drop-in solution. Other inductance values, higher current ratings and special high-temp designs (150° C ambient temperatures) are available upon request.

Features

  • Surface mount design (can convert to TH upon request)
  • High attenuation over a broad frequency range up to 500 MHz
  • Available as a sector (suffix S) winding or bifilar winding design
    • (Sector: provides less capacitance between windings)
    • (Bifilar: provides better coupling between windings, less leakage)
  • Fully RoHS compliant
  • Meet lead-free reflow level J-STD-020C
  • Manufactured in an ISO 9001 certified facility

CMJ Series – SMD Miniature Common Mode Chokes

The CMJ common mode choke series is also designed for SMD (surface mount) applications and pick and place compatibility. As with our CLJ-2 Series, our CMJ series provides excellent coplanarity, which means you don’t have to worry about mounting issues.

Features

  • Miniature, low-cost solution
  • High attenuation over a wide frequency range
  • Manufactured in an ISO 9001 certified facility
