Wurth Elektronik STAR-TEC Series Ferrite Sleeve, 175Ω Impedance at 25Mhz, 316Ω Impedance at 100MHz - 74271111S
This ferrite sleeve is an openable snap ferrite designed to suppress cable-borne EMI/RFI in both safety-relevant and general contexts. It provides a single 5mm aperture for through-cable installation and is manufactured from 4W620 material. The component conforms to RoHS and REACH standards and is intended for inline noise attenuation where removable, Snap-on ferrite cores are required.
Features and Benefits:
• 175Ω impedance at 25MHz delivers low-frequency noise attenuation
• 316Ω impedance at 100MHz improves high-frequency suppression
• Openable snap design enables quick retrofit installation
• Single-aperture format simplifies routing for individual cables
• 4W620 material provides consistent magnetic properties
• 316Ω impedance at 100MHz improves high-frequency suppression
• Openable snap design enables quick retrofit installation
• Single-aperture format simplifies routing for individual cables
• 4W620 material provides consistent magnetic properties
Applications
• Suitable for cable noise suppression in control systems
• Used with signal leads in safety-relevant
• Ideal for retrofit EMI reduction on interconnects
• Can be used for single-cable suppression in consumer equipment
• Used for attenuation where removable ferrite beads are needed
• Used with signal leads in safety-relevant
• Ideal for retrofit EMI reduction on interconnects
• Can be used for single-cable suppression in consumer equipment
• Used for attenuation where removable ferrite beads are needed
What aperture size does it accept?
It accommodates a 5mm cable diameter through its single aperture.
Is the component suitable for retrofitting existing wiring?
Yes, the openable snap construction allows installation without disconnecting the cable.
What approvals does it carry for regulatory handling?
It meets RoHS and REACH compliance requirements.
Which material defines its magnetic performance?
The core is produced from 4W620 material specified for its impedance characteristics.
