SMB2.5R-2

Overview

The Delevan SMB2.5R-2 is a surface-mount ferrite chip bead designed for electromagnetic interference suppression in compact electronic assemblies. This component features a shielded construction that minimizes external magnetic field leakage while providing effective noise attenuation across high-frequency bands. It offers an impedance of 490 Ohms at 100 MHz, supporting a maximum DC current rating of 9.5 A with a low DC resistance of 5 mOhms. The device operates reliably within a temperature range of -40°C to +125°C and utilizes SMD/SMT termination styles for automated assembly integration.

Feature Summary

• Shielded surface-mount design for enhanced EMI suppression
• High current handling capability suitable for power lines
• Low DC resistance to minimize signal loss
• Wide operating temperature range for industrial environments

Applications

• Power supply input filtering
• High-speed data line noise suppression
• Industrial control system EMC compliance
• Automotive electronics EMI reduction

Procurement Notes

Verify the specific suffix designation against official API Delevan documentation to confirm exact electrical characteristics and physical dimensions. Ensure compatibility with existing PCB footprint requirements and reflow soldering profiles. Confirm moisture sensitivity level ratings prior to storage and handling procedures to maintain component integrity during assembly processes.

Selection Notes

Select this component when high current capacity is required alongside significant impedance at 100 MHz. The shielded architecture makes it suitable for applications where magnetic coupling to adjacent components must be minimized. Evaluate thermal management needs given the 125°C upper limit and ensure the 9.5A rating aligns with peak operational loads without exceeding safe operating areas.

Part Context

This part belongs to the SMB2.5R series of shield beads from API Delevan, engineered for surface-mount technology applications. The series provides compact solutions for suppressing electromagnetic interference in dense circuit layouts. These components are specifically designed to offer superior performance compared to unshielded alternatives while maintaining small form factors compatible with modern manufacturing standards.

Replacement Considerations

Consult official manufacturer substitution guides for verified equivalents. Cross-reference impedance curves and current ratings carefully when considering alternative ferrite bead suppliers to ensure functional parity in noise suppression performance and thermal stability under load conditions.
