74270162

Overview

The Wurth Elektronik part number 74270162 is a cylindrical ferrite core belonging to the WE-AFB series. It is designed for axial cable installation with a single turn configuration. The component features an inner diameter of 6.75 mm and an outer diameter of 11 mm, with a total length of 15 mm. It provides an impedance of 94 Ohms at 15 MHz and 59 Ohms at 25 MHz. The material composition is optimized for high-frequency noise suppression in electronic circuits.

Feature Summary

• Cylindrical geometry facilitates easy axial sliding onto cables
• Single-turn design simplifies installation on existing wiring
• Optimized magnetic material for effective high-frequency attenuation

Applications

• Noise suppression on power supply cables
• EMI filtering on data transmission lines
• Common mode choke applications for single conductors

Procurement Notes

Verify the specific impedance frequency points against your application requirements, as values vary across the WE-AFB series. Confirm that the 6.75 mm inner diameter accommodates the target cable insulation thickness. Ensure compliance with RoHS directives if required by your manufacturing standards. Cross-reference the datasheet for temperature stability ratings before final selection.

Selection Notes

Select this model when a snap-on or slide-on ferrite solution is preferred over split cores. The cylindrical shape requires access to both ends of the cable during installation. Compare impedance curves with other WE-AFB variants to ensure adequate attenuation at the specific interference frequencies present in your system environment.

Part Context

This component is part of the WE-AFB family from Wurth Elektronik, which specializes in passive components for electromagnetic compatibility. The series offers various dimensions and materials to address different cable sizes and frequency ranges. It serves as a standard solution for mitigating radiated emissions in compact electronic assemblies.

Replacement Considerations

Check for alternative part numbers within the same WE-AFB series that may offer different impedance characteristics or physical dimensions. Verify compatibility with existing cable bundles before substituting.
