The SMCC-201X-31 is a SMD (Surface Mount Device) Common Mode Choke from Fastron. Supreme Components International is an authorised distributor of Fastron electronic components, ensuring you receive genuine parts. Common mode chokes are essential for reducing electromagnetic interference (EMI) and noise in electronic circuits. They effectively suppress common-mode currents while allowing differential-mode signals to pass through with minimal attenuation. This particular SMD common mode choke is designed for automated assembly, making it suitable for high-volume production. While detailed specifications are unavailable, common mode chokes are typically used in applications such as power supplies, data lines, and signal lines to improve signal integrity and reduce unwanted noise.
