The CMM21T-361M-N is a common mode choke from Chilisin. Common mode chokes are used to suppress common-mode noise in electronic circuits. Common-mode noise is unwanted electrical noise that appears simultaneously on multiple signal lines with respect to a common reference, such as ground.

Applications:

• Power lines
• Signal lines
• USB interfaces
• Audio lines
• Data communication lines

Features:

• High common mode impedance
• Low differential mode impedance
• Compact size
• Surface mount technology (SMT)
• High reliability

Benefits:

• Effective suppression of common mode noise
• Minimal impact on differential signals
• Space-saving design
• Easy to integrate into circuit designs
• Improved signal integrity

Additional Details:

The CMM21T-361M-N features a common mode impedance of 360 ohms at 100 MHz. The 'M' in the part number indicates the tolerance of the inductance. The choke is designed for surface mount assembly, making it easy to integrate into automated manufacturing processes. The compact size allows for use in space-constrained applications. Common mode chokes work by presenting a high impedance to common mode currents while allowing differential mode currents to pass through with minimal attenuation. This is achieved through the winding configuration of the choke. The choke consists of two identical windings on a common core, wound in such a way that the magnetic fields generated by differential mode currents cancel each other out, while the magnetic fields generated by common mode currents add together, creating a high impedance. This component is crucial in ensuring compliance with electromagnetic compatibility (EMC) regulations. It effectively prevents unwanted noise from radiating out of the equipment and protects the equipment from external noise sources. Chilisin is a reputable manufacturer of passive components, and their products are known for their quality and reliability. The CMM21T-361M-N is designed to meet industry standards and provide consistent performance over a wide range of operating conditions.
