74272222

Overview

The Würth Elektronik part number 74272222 is a snap-on ferrite core from the STAR-TEC LFS series, designed for electromagnetic interference suppression. It features a manganese zinc material composition with an internal diameter of 12.5 mm and external dimensions of 33.5 mm x 28.4 mm x 41.6 mm. The component provides an impedance of 35 Ω at 25 MHz and 140 Ω at 100 MHz. It utilizes a quick-install design with a safety key mechanism and is rated for operating temperatures between -25°C and +105°C.

Feature Summary

• Snap-on design with integrated safety key technology for secure installation
• Manganese zinc material optimized for high-frequency noise suppression
• Quick-install mechanism eliminates the need for tools during assembly

Applications

• Electromagnetic interference suppression in digital equipment
• Noise filtering for flat cables and wiring harnesses
• General electronic applications requiring rapid EMI mitigation

Procurement Notes

Verify the specific manufacturing status and availability directly with authorized distributors or the manufacturer, as supply chain conditions may vary. Confirm that the requested quantity matches current stock levels and lead times before finalizing orders. Ensure compliance with RoHS and REACH standards if required by your project specifications. Cross-reference the datasheet to confirm dimensional and electrical parameters match your design requirements.

Selection Notes

Select this component when a snap-on solution is preferred over split-core or clamp types for faster assembly. The 12.5 mm inner diameter accommodates cables or wires within that size range. Choose based on the required impedance profile at target frequencies, specifically noting the 140 Ω value at 100 MHz. Consider the physical space constraints due to its external dimensions of 33.5 mm x 28.4 mm x 41.6 mm.

Part Context

This part belongs to the WE-STAR-TEC LFS family of snap ferrites, which are engineered for efficient EMI/RFI protection. The series emphasizes ease of use through its snap-fit design while maintaining robust performance characteristics. It complements other Würth Elektronik passive components used in EMC filtering and signal integrity management across various industrial and consumer electronics applications.
