7427144

Overview

The Würth Elektronik 7427144 is a snap-on ferrite core designed for electromagnetic interference suppression. It features a grey plastic housing with an internal aperture diameter of 11.0 mm, accommodating cables up to this thickness. The component exhibits an impedance of 129 Ohms at 100 MHz. Its physical dimensions are 34.5 mm in length, 30 mm in width, and 17 mm in height. This hardware accessory belongs to the STAR-TEC series and is intended for clamping onto wires to enhance signal integrity.

Feature Summary

• Snap-on design allows for rapid installation without cable disconnection
• Plastic housing provides mechanical protection and secure fit
• High impedance characteristics effective for noise attenuation

Applications

• Suppression of common mode noise on data cables
• EMI reduction in industrial control wiring
• Signal integrity enhancement for communication lines

Procurement Notes

Verify the exact part number against official Wurth Elektronik documentation before procurement. Confirm that the required impedance value and physical aperture size match the specific application requirements. Check current manufacturing status as availability may vary. Ensure compliance with relevant safety standards for the target environment.

Selection Notes

Select this component when a non-invasive noise suppression solution is required for cables with diameters up to 11.0 mm. Consider the 129 Ohm impedance at 100 MHz for high-frequency noise environments. Evaluate spatial constraints against the 34.5 x 30 x 17 mm footprint. Compare with alternative series if different mounting styles or impedance profiles are needed.
