74271633

Overview

The Würth Elektronik 74271633 is a split core ferrite clamp from the STAR-GAP series, designed for RF applications. It features an 8 mm aperture and utilizes 4W620 material. The component provides an impedance of 100 Ω at 100 MHz, 28 Ω at 25 MHz, 250 Ω at 300 MHz, and 354 Ω at 500 MHz. Its physical dimensions are 21.7 mm in depth, 35.1 mm in width, and 19 mm in height. The unit includes a wrench for installation and complies with REACH and RoHS standards.

Feature Summary

• Snap-fit design allows for rapid installation on existing cables without disconnection
• Utilizes 4W620 ferrite material to provide effective common mode noise suppression
• Includes integrated wrench mechanism to ensure secure closure and consistent clamping force

Applications

• General EMI/RFI noise suppression
• Safety-related electronic applications
• Cable harness filtering in industrial equipment

Procurement Notes

Verify the specific suffix 'S' in part number 74271633S against official Wurth Elektronik documentation to confirm inclusion of the installation wrench. Ensure the selected variant matches the required impedance profile for the target frequency range. Cross-reference the 4W620 material specification to validate thermal and magnetic performance requirements for the intended operating environment.

Selection Notes

Select this component when retrofitting ferrite suppression onto cables with diameters up to 8 mm. The STAR-GAP series is suitable for applications requiring quick assembly and removal. Compare impedance values at 100 MHz and 300 MHz against other series options like STAR-TEC or STAR-RING to determine if the 100 Ω characteristic meets the specific noise attenuation needs of the circuit.

Part Context

This component belongs to the STAR-GAP family of snap-on ferrites manufactured by Würth Elektronik. These parts are engineered for high-frequency interference mitigation. The 74271633 specifically targets mid-range cable diameters, offering a balance between aperture size and magnetic cross-section for effective noise absorption in compact spaces.

Replacement Considerations

Direct substitutes include other Wurth Elektronik snap ferrites with similar 8 mm apertures and 4W620 material, such as those in the STAR-TEC series, provided impedance curves align with the application's noise spectrum.
