Common Mode Chokes (CMCs) are electronic components used to restrict the flow of electrical signals. CMCs can be used to provide common mode noise attenuation, impedance matching, and RF signal isolation. Of particular importance are CMCs that are used to suppress common mode noise in high speed data applications. CAX-1.3-3.9 are one such type of CMCs.

The CAX-1.3-3.9 CMCs are small, laminated ferrite core devices with a tight, low impedance winding on the device. The windings are designed to create a high impedance to common mode signals, while still allowing the flow of a differential signal. This helps to reduce EMI noise in high-speed transmissions.

The CAX-1.3-3.9 CMCs are typically used in communications and data applications that require high frequency signal transmission such as USB, HDMI, and SDI. They are also suitable for power circuits, industrial drives, and other applications that require common mode noise suppression. The CAX-1.3-3.9 CMCs are capable of operating over a temperature range of -40°C to +110°C.

In terms of working principles, the CMCs are designed to block the passage of common mode noise. The core is made of a ferrite material that creates a magnetic field, which prevents the passage of common mode noise. The winding of the CAX-1.3-3.9 CMCs creates a further barrier to the passage of common mode noise, creating high common mode impedance. This also helps to create a good differential mode impedance.

The CMCs are also designed to provide a low insertion loss. This is important to ensure that the signal is not degraded during transmission. The core material and winding configuration of the CAX-1.3-3.9 CMCs are designed to minimize loss and ensure a high signal quality. Additionally, the CMCs are designed to be self-resonant, meaning that they are not prone to harmonic distortion.

In summary, the CAX-1.3-3.9 CMCs are small, high impedance choke coils designed to provide common mode noise suppression in a wide range of applications. The CMCs are designed to minimize insertion loss and harmonic distortion, and are capable of operating over a wide temperature range. The CMCs have a variety of valuable features that make them an ideal choice for applications that require high frequency signal transmission and common mode noise suppression.
