Wurth Elektronik STAR-TEC Series Ferrite Sleeve, 13mm Aperture, 158Ω Impedance at 25MHz - 74271221
This ferrite sleeve is an openable core designed for general EMI suppression on cable runs. It provides frequency-dependent impedance to reduce interference in electronic assemblies while allowing simple retrofitting to existing wiring. The component is MADE from material 4W620 and includes a single pass-through aperture for straightforward installation in applications requiring removable attenuation.
Features and Benefits:
• 158Ω impedance at 25MHz for low-frequency attenuation
• 278Ω impedance at 100MHz for mid-high frequency suppression
• Openable design enabling quick clamp-on installation
• Single aperture construction ensuring consistent cable placement
• REACH and RoHS approvals supporting regulatory conformity
• 278Ω impedance at 100MHz for mid-high frequency suppression
• Openable design enabling quick clamp-on installation
• Single aperture construction ensuring consistent cable placement
• REACH and RoHS approvals supporting regulatory conformity
Applications
• Suitable for noise reduction in power-supply leads
• Ideal for EMI control in signal-cable assemblies
• Used with harnesses requiring removable suppression elements
• Can be used for retrofitting existing equipment cabling
• Suitable for general-application electronic assemblies
• Ideal for EMI control in signal-cable assemblies
• Used with harnesses requiring removable suppression elements
• Can be used for retrofitting existing equipment cabling
• Suitable for general-application electronic assemblies
What are the external physical sizes of the component?
The outer dimensions measure 33.6mm depth, 29.5mm height and 37.7mm width.
How large is the aperture for cable routing?
The through-hole diameter is 13mm to accept standard cable diameters.
What material is the core manufactured from?
It is produced using material 4W620 chosen for its magnetic-loss characteristics.
Is the unit suitable for multiple cable passes?
It is configured with a single aperture intended for one cable pass only.
