- Features low DC resistance for minimal signal loss
Applications
- Power line filtering
- Signal line EMI suppression
- General-purpose electromagnetic interference reduction
Procurement Notes
This component is officially obsolete and no longer in production. Procurement must rely on secondary market distributors or verified direct substitutes. Verify the exact suffix, such as -10, which indicates specific packaging or tape-and-reel configurations. Confirm RoHS compliance status and manufacturer lot codes when sourcing from non-original suppliers to ensure authenticity and quality.
Selection Notes
Select this component for circuits requiring axial ferrite beads with a 5A current capacity. Ensure the design accommodates the open radial bent lead form factor for through-hole assembly. Verify that the 143 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum. Consider the physical dimensions of 0.138 inches diameter during PCB layout planning.
Part Context
The 28J series represents Laird's axial ferrite bead lineup, characterized by robust current handling and standardized impedance profiles. These components are engineered for reliable EMI filtering in industrial and commercial electronics. The 28J0138-11R specifically utilizes a material formulation optimized for broadband noise attenuation while maintaining structural integrity under thermal stress.
Replacement Considerations
The direct substitute is 28L0138-50R-10. Both parts share identical electrical specifications and mechanical dimensions, ensuring pin-to-pin compatibility without circuit redesign.
