Wurth Elektronik WE-AFB-EMI Series Ferrite Bead, 12.50mm Diameter, 7W380 - 742700790

This ferrite bead is an axial EMI suppression component designed to attenuate high-frequency interference on wiring assemblies. It is intended for wrapping individual conductors, multiconductor cables and coaxial lines, operating in environments between -25°C and 125°C. The part is halogen-free and conforms to relevant RoHS and REACH specifications, making it suitable for designs requiring reduced halogen content and regulated substance declarations.

Features and Benefits:

• 127Ω impedance at 25MHz reduces low-frequency conducted emissions
• 218Ω impedance at 100MHz attenuates higher-frequency noise
• Axial form factor supports inline placement on wires for easy installation
• Halogen-free composition meets modern material restriction requirements
• Wide operating temperature range allows use in varied thermal conditions

Applications

• Suitable for wrapping cable to suppress EMI on signal runs
• Ideal for axial placement on coaxial cable to reduce interference
• Used with multiconductor wire assemblies to limit crosstalk
• Can be used for single-wire EMI mitigation in harnesses
• Suitable for wire installations where halogen-free materials are required
