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

What mounting orientation is required for installation?

The component is axial in form and is intended to be slipped along the conductor so the bead encircles the insulation.

Which approvals indicate restricted-substance compliance?

It conforms to RoHS and REACH declarations and meets halogen-free standards referenced in JEDEC and IEC documents.

How does temperature affect performance range?

Electrical characteristics are specified for operation within -25°C to 125°C and should be maintained within these limits for consistent attenuation.

For which cable types is this component compatible?

It is suitable for individual wires, multiconductor cables and coaxial cable where axial beads can be applied.
