Wurth Elektronik STAR-GAP Series Ferrite Sleeve, 35.1mm External Depth, 8mm Aperture Diameter - 74271633S

This ferrite sleeve is a gapped, openable ferrite component intended for general-application use where EMI suppression is required. It is manufactured from material grade 4W620 and designed to be opened for straightforward installation around cables or harnesses. The component meets REACH and RoHS standards and provides frequency-dependent impedance to attenuate unwanted interference across a broad spectrum.

Features and Benefits:

• High impedance at 500MHz delivers strong high-frequency suppression
• 100 Ω impedance at 100MHz reduces mid-band noise effectively
• 28 Ω impedance at 25MHz improves low-frequency attenuation
• Gapped design controls magnetic characteristics for tailored performance
• Openable construction allows Rapid retrofitting on existing cabling

Applications

• Suitable for suppression on signal and power leads
• Ideal for retrofitting to wiring looms in assemblies
• Used with equipment needing controlled magnetic response
• Can be used for EMI control in industrial installations
• Appropriate for cable runs requiring a single-aperture core

What aperture size accommodates typical cable diameters?

The internal opening measures 8mm, permitting single-conductor routing through the core.

How many passages are available for cables through the part?

It features one aperture designed for individual cable or bundle placement.

Which standards govern the material restrictions for this item?

The construction complies with REACH and RoHS requirements for restricted substances.

What physical form factor aids installation in confined spaces?

The unit is openable, enabling clasping onto existing cables without disassembly.

How does the gap affect magnetic behaviour?

The presence of a gap modifies the magnetic path to adjust impedance and prevent saturation.
