74270073

Overview

The Würth Elektronik 74270073 is a cylindrical ferrite core from the WE-SAFB series, designed for electromagnetic interference (EMI) suppression. Constructed from 7W850 material, it features an inside diameter of 1.2 mm and an outside diameter of 3.8 mm. The component has a length of 4 mm and operates within a temperature range of -25°C to +125°C. It provides an impedance of 50 Ω at 100 MHz.

Feature Summary

• Cylindrical form factor for direct cable installation
• High-frequency EMI noise attenuation capability
• Suitable for compact electronic assemblies

Applications

• Transistor base line filtering
• Feed line noise suppression
• General EMI mitigation on small cables

Procurement Notes

Verify the specific impedance value required for your application against the datasheet specifications. Confirm that the cable diameter fits within the 1.2 mm inner diameter constraint. Ensure compliance with RoHS and REACH standards if mandated by your project requirements before finalizing procurement.

Selection Notes

Select this component when space constraints require a small cylindrical ferrite bead. The 1.2 mm bore size limits usage to thin wires or leads. Consider the 50 Ω impedance at 100 MHz to ensure effective attenuation for the target noise frequencies. Verify thermal stability requirements against the specified operating temperature range.

Part Context

This part belongs to the WE-SAFB series of ferrite beads manufactured by Würth Elektronik. These components are engineered for surface-mount or through-hole integration where minimal footprint is critical. The series utilizes specific ferrite compounds optimized for high-frequency absorption rather than reflection.

Replacement Considerations
