74271622

Overview

The Würth Elektronik 74271622 is a square snap-on ferrite core from the STAR-GAP series, designed for electromagnetic interference suppression. It features an internal diameter of 12.5 mm and is constructed from 4W620 material. The component provides an impedance of 140 ohms at 100 MHz. External dimensions are 32.5 mm in length, 30.3 mm in width, and 28.2 mm in height. It utilizes a grey color code and includes a safety key mechanism.

Feature Summary

• Snap-on design with integrated safety key for secure cable retention
• Square geometry optimized for space-constrained applications
• High impedance performance at 100 MHz using 4W620 material

Applications

• RF applications requiring effective EMI suppression
• Cable protection for wires up to 12.5 mm diameter
• General electromagnetic interference mitigation

Procurement Notes

Verify the exact part number suffix when ordering, as variations such as 74271622S may exist within the same product family. Confirm that the required impedance level of 140 ohms at 100 MHz aligns with your specific circuit requirements. Ensure compatibility with the target cable diameter of 12.5 mm before procurement.

Selection Notes

Select this component when a snap-on solution is preferred over split-core alternatives for ease of installation on existing cables. The 12.5 mm inner diameter accommodates standard cable sizes. Consider the 140 ohm impedance at 100 MHz as the primary filtering characteristic for high-frequency noise reduction.

Part Context

This component belongs to the STAR-GAP series of ferrite cores manufactured by Würth Elektronik. The series is characterized by snap-on designs that facilitate quick installation without disconnecting cables. The 4W620 material composition ensures stable magnetic properties across varying environmental conditions.

Replacement Considerations

The 74271622S is a related variant within the STAR-GAP series. Verify dimensional and impedance specifications before substituting. No other direct public substitutes are confirmed.
