Wurth Elektronik STAR-TEC Series Ferrite Clamp, 125Ω Impedance at 25Mhz, 235Ω Impedance at 100MHz - 74271131
This ferrite clamp is an openable single-aperture component designed to reduce conducted interference in general application wiring. It is manufactured from 4W620 material and provides frequency-dependent impedance to suppress high-frequency noise across common signal and power cables. The product is suitable for inline installation where a removable clamp format is required and conforms to RoHS and REACH directives.
Features and Benefits:
• 125Ω impedance at 25MHz provides low-frequency attenuation
• 235Ω impedance at 100MHz offers mid-band suppression
• 145Ω impedance at 500MHz improves high-frequency rejection
• 7.5mm aperture accepts single cable routing
• Openable design allows retrofit installation without cable disconnection
• 235Ω impedance at 100MHz offers mid-band suppression
• 145Ω impedance at 500MHz improves high-frequency rejection
• 7.5mm aperture accepts single cable routing
• Openable design allows retrofit installation without cable disconnection
Applications
• Suitable for cable noise reduction on control wiring
• Used with harnesses requiring retrofit EMI suppression
• Can be used for suppression on signal and data lines
• Ideal for assemblies needing removable interference clamps
• Used with harnesses requiring retrofit EMI suppression
• Can be used for suppression on signal and data lines
• Ideal for assemblies needing removable interference clamps
What material is used for the core and why?
The clamp is formed from 4W620 ferrite material chosen for its frequency-dependent permeability that provides impedance across a broad spectrum.
What physical size should be allowed for mounting?
The external footprint measures 36.4 x 24.6 x 20.1mm so allowance for that envelope is required during installation.
How many cables can be passed through the clamp?
A single aperture of 7.5mm diameter is provided, intended for one conductor or bundled cable within that diameter.
Are there regulatory restrictions affecting use in assemblies?
The component meets RoHS and REACH approvals, indicating compliance with applicable substance restrictions for integration.
