7427221

Overview

The Würth Elektronik 7427221 is a solid ferrite cable core from the WE-FLAT series, designed for electromagnetic interference suppression. It exhibits an impedance of 166 Ohms at a test frequency of 100 MHz. The component features internal dimensions of 14 mm length and 1 mm height, with external dimensions of 8 mm depth, 18 mm width, and 5 mm height. Constructed from 4 W 620 material, it supports a maximum operating temperature of +125°C and a minimum of -25°C. The unit weighs approximately 2.657 grams.

Feature Summary

• Solid construction designed specifically for flat ribbon cables
• Provides high impedance characteristics for effective noise suppression
• Compatible with digital equipment applications requiring EMI control

Applications

• Flat ribbon cable integration
• Digital equipment signal integrity enhancement
• Electromagnetic interference suppression in general electronic systems

Procurement Notes

Verify the manufacturer part number 7427221 against official Wurth Elektronik documentation to ensure authenticity. Confirm that the specific WE-FLAT series designation matches project requirements. Check RoHS compliance status through current datasheets. Validate dimensional tolerances and material specifications (4 W 620) prior to procurement to avoid integration issues.

Selection Notes

Select this component when flat ribbon cable geometry is required for EMI mitigation. The 166 Ohm impedance at 100 MHz suits high-frequency noise reduction. Ensure the internal opening accommodates the target cable thickness. Consider the operating temperature range of -25°C to +125°C for environmental compatibility. Verify physical space constraints against the external dimensions of 18x8x5 mm.

Part Context

This part belongs to the WE-FLAT series of solid ferrite cores manufactured by Würth Elektronik. Unlike split-core designs, these are solid units intended for installation during cable assembly or manufacturing stages. The series focuses on providing standardized impedance profiles for flat cabling solutions used in consumer and industrial electronics.
