74272151

Overview

The Würth Elektronik 74272151 is a snap-on ferrite core from the STAR-TEC series, designed for electromagnetic interference suppression. It features a manganese-zinc material composition and a square shape with a single opening. The component has an inner diameter of 15 mm and external dimensions of 39 mm x 35 mm x 49 mm. It exhibits an impedance of 195 Ω at 25 MHz and 340 Ω at 100 MHz. The device operates within a temperature range of -25°C to +105°C and includes a wrench for installation.

Feature Summary

• Snap-on design allows for rapid installation on existing cables without disconnection.
• Square cross-section provides structural stability for secure cable retention.
• Integrated wrench facilitates tight closure of the split core housing.

Applications

• Electromagnetic interference suppression
• Power cable noise reduction
• Computer data line filtering

Procurement Notes

Verify the specific impedance requirements against application frequency spectra before ordering. Confirm that the target cable diameter fits within the 15 mm inner diameter specification. Check for RoHS and REACH compliance documentation if required by regional regulations. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.

Selection Notes

Select this model when high impedance at 100 MHz is required for broadband noise attenuation. The 15 mm aperture accommodates thicker cables compared to smaller STAR-TEC variants. Consider the inclusion of the wrench as a functional advantage for field installations where manual tightening is necessary. Compare physical dimensions against available space constraints in the enclosure.

Part Context

This component belongs to the STAR-TEC series of snap-on ferrites manufactured by Würth Elektronik. These cores utilize 4W620 material optimized for common mode noise suppression in the VHF/UHF range. The series offers various aperture sizes to suit different cable diameters while maintaining consistent mounting characteristics.
