74275812S

Overview

The Würth Elektronik part number 74275812S is a split core ferrite component belonging to the WE-STAR-BUENO series. It features an internal width of 5 mm and provides an impedance of 200 Ω at 100 MHz, extending up to 1 GHz. The unit incorporates an optical closing control mechanism for secure engagement. External dimensions are approximately 30.3 mm in length, 19 mm in width, and 18.4 mm in height. The device complies with RoHS standards and is designed for general electronic equipment applications.

Feature Summary

• Incorporates an optical closing control mechanism to verify secure engagement of the split core halves.
• Features an internal prefixing cable system designed to facilitate the cable assembly process.
• Utilizes a security lock design to maintain structural integrity during operation.

Applications

• General electronic equipment
• Cable assembly processes requiring verified closure
• EMI suppression for cables fitting within 5 mm diameter

Procurement Notes

Verify the specific series designation (WE-STAR-BUENO) and optical locking feature against official datasheets before procurement. Confirm that the 5 mm internal width matches the target cable diameter precisely. Ensure compliance requirements such as RoHS are documented in the final bill of materials. Cross-reference the external dimensions to confirm spatial fit within the intended enclosure or mounting area.

Selection Notes

Select this component when visual verification of ferrite installation is required due to its unique optical closing mechanism. Choose this model over standard snap ferrites if the application demands a higher assurance of physical connection integrity. Consider the 200 Ω impedance profile at 100 MHz for high-frequency noise suppression needs. Evaluate the 5 mm aperture constraint to ensure compatibility with the specific cable bundle size being treated.

Part Context

This component is part of the WE-STAR-BUENO series from Würth Elektronik, which specializes in split core ferrites with enhanced installation verification features. Unlike standard openable ferrites, this series integrates mechanical and optical indicators to confirm proper closure. It serves as a specialized solution for applications where standard ferrite retention cannot be guaranteed visually or mechanically alone.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Standard split core ferrites lack the optical closing mechanism and may not provide equivalent installation verification. Any replacement must be validated against the specific impedance curve and dimensional constraints of the original design.

FAQ
