MFBM1V1608-181-R

Overview

The Eaton MFBM1V1608-181-R is a multilayer chip ferrite bead designed for surface-mount technology applications. It operates within a temperature range of -40°C to +85°C and features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 180 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1.5 A and has a maximum DC resistance of 90 mOhms. This single-channel device is shielded and complies with RoHS standards.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Shielded design to contain magnetic fields
• High saturation current capability suitable for power line filtering

Applications

• Power supply output filtering
• DC-DC converter noise suppression
• General-purpose EMI suppression in compact electronics

Procurement Notes

Verify the specific impedance value and current rating against the target circuit requirements before ordering. Confirm that the 0603 footprint matches the PCB layout. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check for any specific packaging preferences such as cut tape or reel quantities if applicable to the production process.

Selection Notes

Select this component when a balance between high current handling and moderate impedance is required in a small form factor. The 1.5 A rating allows it to handle significant load currents without excessive saturation. The low DC resistance minimizes voltage drop across the component during normal operation. Consider the 180 Ohm impedance profile at 100 MHz to ensure adequate attenuation for the specific noise frequencies present in the application.
