SMB2.5R-1

Overview

The Delevan SMB2.5R-1 is a surface-mount shield bead from the SMB2.5R series, designed for high-current electromagnetic interference suppression. It features an impedance of 385 Ohms at 100 MHz and supports a maximum DC current of 9.5 A. The component utilizes a two-terminal SMD J-lead termination style with a low DC resistance of 5 mΩ. Its physical dimensions are 11.68 mm in length, 7.2 mm in width, and 5.08 mm in height. The device operates within a temperature range of -40°C to +125°C and holds a Moisture Sensitivity Level of 1.

Feature Summary

Compact surface-mount design for effective EMI suppression
High current handling capability up to 9.5 A
Low DC resistance for minimal signal loss

Applications

Power supply line filtering
High-current circuit noise reduction
Electromagnetic interference suppression in compact PCB layouts

Procurement Notes

Verify the specific impedance value of 385 Ohms at 100 MHz against your filter requirements. Confirm the 9.5 A current rating suits your operational load. Ensure the J-lead footprint matches your PCB design. Check the -40°C to +125°C operating range for environmental compatibility. Validate the 5 mΩ DC resistance impact on your circuit efficiency.

Selection Notes

Select this component when high current capacity is required alongside significant impedance at 100 MHz. The large physical size accommodates the 9.5 A rating but requires adequate board space. Consider the J-lead termination for robust mechanical attachment. Evaluate the thermal performance given the high current flow through the 5 mΩ resistance.

Part Context

This part belongs to the SMB2.5R series of shield beads manufactured by API Delevan. These components are engineered as surface-mount suppressors offering a balance between compactness and high-performance noise attenuation. The series is characterized by its ability to handle substantial DC currents while providing targeted impedance for high-frequency noise control.
