742701716

Overview

The Würth Elektronik part number 742701716 is a WE-TOF EMI suppression toroidal ferrite core. It features a round, solid design with an inner diameter of 7.9 mm and an outer diameter of 12.7 mm. The component has a length of 6.35 mm (0.250 inches) and provides an impedance of 100 ohms. It is designed for free-hanging mounting applications to suppress electromagnetic interference in electronic circuits.

Feature Summary

• Round solid toroidal geometry for uniform magnetic flux distribution
• Designed for effective EMI suppression in signal and power lines
• Free-hanging mounting style allows flexible installation on cables

Applications

• Electromagnetic interference suppression on data cables
• Noise filtering on power supply lines
• Signal integrity enhancement in sensitive electronic assemblies

Procurement Notes

Verify the specific impedance rating and physical dimensions against the official Wurth Elektronik datasheet before integration. Confirm that the 7.9 mm inner diameter accommodates the target cable or wire gauge without excessive strain. Ensure the material composition meets the required frequency response characteristics for the intended application environment.

Selection Notes

Select this component when a compact, round toroidal ferrite is required for high-frequency noise attenuation. The 100 ohm impedance at the specified frequency makes it suitable for general EMI suppression tasks. Consider the free-hanging form factor if space constraints prevent the use of clamp-on cores or if direct cable wrapping is preferred for maximum coupling efficiency.

Part Context

This part belongs to the WE-TOF series of EMI suppression components from Wurth Elektronik. These toroidal cores are engineered to provide reliable noise reduction across various electronic systems. The series offers different sizes and impedance values to match specific cable diameters and frequency requirements, ensuring effective electromagnetic compatibility compliance.
