35F0121-1SR-10

Overview

The 35F0121-1SR-10 is a single-line ferrite bead manufactured by Laird-Signal Integrity Products, designed for power line filtering applications. It features an impedance of 82 Ohms at 100 MHz and supports a maximum current rating of 10A. The component has a maximum DC resistance (DCR) of 1mOhm and utilizes a 2-SMD J-Lead package with dimensions of 3.05mm x 2.54mm. It operates within a temperature range of -40°C to 125°C.

Feature Summary

• Provides effective electromagnetic interference suppression for high-current power lines
• Utilizes a compact surface-mount J-lead package for automated assembly
• Maintains low DC resistance to minimize voltage drop in power circuits

Applications

• High-frequency circuit noise filtering
• Power line signal conditioning
• Electromagnetic interference suppression in electronic devices

Procurement Notes

Verify the specific suffix and manufacturer designation when sourcing, as variants may exist. Confirm RoHS compliance status directly with the supplier or official documentation, as regulatory statuses can change over time. Ensure the selected packaging type matches your production requirements. Cross-reference the DigiKey part number 240-2442-2-ND for additional distributor details if needed.

Selection Notes

Select this component for applications requiring high current handling capability alongside significant impedance at 100 MHz. The 10A rating makes it suitable for main power rails where lower impedance beads would saturate. Consider the physical footprint and J-lead configuration for PCB layout compatibility. Verify thermal performance under continuous load conditions.

Part Context

This component belongs to the 35F series of ferrite beads from Laird-Signal Integrity Products. It is functionally similar to the 28F0121-0SR but offers higher impedance characteristics tailored for specific power line filtering needs. The series is designed for robust EMI suppression in demanding electronic environments.

Replacement Considerations

The 28F0121-0SR is a related variant within the same product family, though impedance and RoHS status may differ. Verify electrical parameters and package compatibility before substitution.
