WURTH ELEKTRONIK 742700221 EMI Noise Filter

The suppression ferrite bead is a small-sized electromagnetic interference (EMI) filter designed to reduce high-frequency noise in electronic circuits. Made from ferrite material, it offers effective filtering capabilities for cables with a maximum diameter of 3.8 mm, and operates within temperature ranges of -25°C to +105°C. Suitable for use in industrial and electronic applications, its typical impedance at 25 MHz is 20 Ω plus 25% tolerance, and at 100 MHz is 45 Ω with a -25% tolerance. The ferrite bead ensures compliance with electromagnetic compatibility standards, enhancing circuit performance and reducing noise interference.
