Wurth Elektronik STAR-TEC Series Ferrite Sleeve, 158Ω Impedance at 25Mhz, 278Ω Impedance at 100MHz - 74271221S
This ferrite sleeve is an openable snap ferrite designed to reduce EMI/RFI interference on single cable runs. It is manufactured from 4W620 material and suits both general and safety-relevant applications. The component provides a single 10.5mm aperture and complies with RoHS and REACH standards, making it suitable for assemblies where regulatory substance limits are required.
Features and Benefits:
• 158Ω at 25MHz for targeted low-frequency suppression
• 278Ω at 100MHz for improved high-frequency attenuation
• Openable snap design for tool-free installation
• Single aperture construction for individual cable damping
• 4W620 material offering consistent magnetic permeability
• 278Ω at 100MHz for improved high-frequency attenuation
• Openable snap design for tool-free installation
• Single aperture construction for individual cable damping
• 4W620 material offering consistent magnetic permeability
Applications
• Suitable for reducing EMI on power leads
• Used with control cables in safety-related systems
• Ideal for retrofitting noise suppression in assemblies
• Can be used for single-cable signal line damping
• Suitable for inline suppression in service panels
• Used with control cables in safety-related systems
• Ideal for retrofitting noise suppression in assemblies
• Can be used for single-cable signal line damping
• Suitable for inline suppression in service panels
What physical form factor facilitates installation in confined spaces?
The part is a Snap-on sleeve with external dimensions 41.6 x 33.5 x 28.4mm enabling Compact placement.
How many conductors can be accommodated through the aperture?
