MFBM1V1005-121-R

Overview

The MFBM1V1005-121-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 800 mA and has a maximum DC resistance of 150 mOhms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Shielded design to contain magnetic fields
• Compact 0402 footprint suitable for high-density PCB layouts

Applications

• Power line filtering in portable electronics
• EMI suppression in data transmission lines
• Noise reduction in clock signal circuits

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging configuration as per manufacturer standards. Confirm RoHS3 compliance status through official documentation before integration. Ensure storage conditions respect moisture sensitivity level 1 requirements to maintain component integrity during assembly processes.

Selection Notes

Select this component when space constraints require a 0402 package size. Choose based on the 120 Ohm impedance requirement at 100 MHz for target noise frequencies. Verify that the 800 mA current rating exceeds the maximum operating current of the circuit to prevent saturation or excessive heating during normal operation.
