MLB03-121-RC

Overview

The MLB03-121-RC is a multilayer ferrite bead manufactured by Allied Components International. It features a 0402 surface-mount package and provides an impedance of 120 ohms at 100 MHz. The component has a DC resistance of 250 milliohms and supports a current rating of 1 ampere. It is designed for noise suppression in high-frequency circuits.

Feature Summary

• Multilayer ferrite construction for effective high-frequency noise attenuation
• Compact 0402 surface-mount footprint suitable for space-constrained designs
• Low DC resistance to minimize signal loss in power lines

Applications

• High-speed data line filtering
• Power supply noise suppression
• EMI reduction in compact electronic devices

Procurement Notes

Verify the specific impedance tolerance and current rating requirements against your circuit design before ordering. Confirm RoHS compliance status with the supplier if environmental regulations apply to your region. Ensure the 0402 package dimensions match your PCB layout constraints. Check for any recent datasheet updates regarding parameter changes.

Selection Notes

Select this component when a low-profile, high-impedance solution is needed for 100 MHz noise suppression. The 250 milliohm DC resistance makes it suitable for applications where minimal voltage drop is critical. Consider the 1 ampere current handling capability to ensure adequate margin for peak loads in your specific application.
