Wurth Elektronik Starfix Series Ferrite Sleeve, 8mm Aperture, 8W5000 - 74272733
This ferrite sleeve is designed to reduce electromagnetic interference on signal and power cables. It functions as an inline choke to suppress conducted emissions and improve signal integrity in assemblies where cable-borne noise is a concern. The component is intended for insertion around conductors to attenuate high-frequency interference in electronic systems.
Features and Benefits:
• 8mm aperture provides targeted attenuation for small-diameter cables
• 8W5000 material delivers high-frequency suppression performance
• EMI suppression capability reduces conducted noise on cable runs
• 8W5000 material delivers high-frequency suppression performance
• EMI suppression capability reduces conducted noise on cable runs
Applications
• Suitable for use with signal cables requiring noise reduction
• Used for attenuation of interference in electronic assemblies
• Ideal for retrofit damping on existing cable harnesses
• Used for attenuation of interference in electronic assemblies
• Ideal for retrofit damping on existing cable harnesses
How is the component installed on cables?
It is slipped over the conductor through its 8mm aperture and positioned where attenuation is required.
What functional effect does the material have on interference?
The 8W5000 composition increases impedance at high frequencies, acting as an EMI choke to diminish conducted emissions.
Note
For cable diameter 4.5 → 8mm ( 736-1920 ) and 8.5 → 12.5 mm ( 736-1923 ). Weight 29g ( 736-1920 ) and 73g ( 736-1923 ).
