74271722S

Overview

The Würth Elektronik 74271722S is a snap-on ferrite core from the STAR-FIX series, designed for rapid installation on cables. It features a single opening with an inner diameter of 12.5 mm and utilizes 4W620 material composition. The component provides an impedance of 270 Ω at 100 MHz and 145 Ω at 25 MHz. External dimensions are 42.2 mm in width, 28.8 mm in height, and 33.5 mm in depth. It operates within a temperature range of -25°C to +105°C and complies with RoHS and REACH standards.

Feature Summary

• Snap-on design with flexible cable fixing mechanism for quick manual installation without tools.
• Constructed from 4W620 ferrite material optimized for high-frequency noise suppression.
• Single-opening configuration allows direct clamping around existing cable assemblies.

Applications

• Power cable noise suppression
• Computer data line filtering
• General EMI suppression on circuit board wiring

Procurement Notes

Verify the specific ordering suffix to ensure the correct package quantity and variant match project requirements. Confirm that the 12.5 mm inner diameter accommodates the target cable assembly size. Check compliance documentation for RoHS and REACH status if required by regulatory frameworks. Ensure storage conditions maintain component integrity prior to installation.

Selection Notes

Select this model when a snap-on solution is preferred over split-core or solid ferrites for ease of retrofitting. The 12.5 mm aperture suits medium-sized cables requiring moderate impedance at 100 MHz. Consider the operating temperature range of -25°C to +105°C for environmental compatibility. Compare impedance curves against specific noise frequencies to validate effectiveness.

Part Context

This component belongs to the STAR-FIX Snap series, which specializes in hinged ferrite cores for efficient cable management. It complements other Wurth Elektronik ferrite solutions by offering tool-free installation capabilities. The series supports various aperture sizes to accommodate different cable diameters while maintaining consistent material properties across the lineup.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users must verify dimensional fit and impedance characteristics carefully when considering alternative manufacturers or series.
