74270053

Overview

The Würth Elektronik part number 74270053 is an axial ferrite bead belonging to the WE-AFB series. It is designed for EMI suppression with a nominal impedance of 195 Ohms at a test frequency of 25 MHz. The component features a solid toroidal geometry with an outer diameter of 16.00 mm, an inner diameter of 9.00 mm, and a length of 28.00 mm. It operates within a frequency range up to 100 MHz and complies with RoHS standards.

Feature Summary

• Provides effective electromagnetic interference suppression through high impedance characteristics
• Solid ring construction allows for easy cable wrapping or insertion
• Compliant with RoHS directives for lead-free manufacturing

Applications

• EMI suppression on coaxial cables
• Noise filtering on wrapped cables
• Suppression on multi-wire harnesses

Procurement Notes

Verify the specific impedance value of 195 Ohms at 25 MHz against design requirements. Confirm physical dimensions match the 16.00 mm outer diameter and 9.00 mm inner diameter constraints. Ensure the application environment falls within the specified operational frequency range up to 100 MHz. Check for RoHS compliance documentation if required by project standards.

Selection Notes

Select this component when high impedance at lower frequencies around 25 MHz is required for noise reduction. The large bore size accommodates thicker cables compared to standard beads. Consider the physical volume of the 28.00 mm length during layout planning. This axial form factor is suitable for manual assembly or dedicated fixtures rather than automated surface mount processes.

Part Context

This component is part of the WE-AFB family of axial ferrite beads manufactured by Würth Elektronik. These components are engineered specifically for suppressing electromagnetic interference in electronic circuits. The series offers various impedance values and physical sizes to suit different cable diameters and noise profiles.

Replacement Considerations

Cross-reference other Wurth Elektronik WE-AFB parts with similar impedance and dimensional specifications. Verify that any substitute maintains the 195 Ohm impedance characteristic at 25 MHz. Ensure the replacement fits the 9.00 mm inner diameter constraint.
