MFBM1V1005-301-R

Overview

The MFBM1V1005-301-R is a single-line multilayer ferrite bead chip manufactured by Eaton Electronics Division. It features an impedance of 300 Ohms at 100 MHz and a maximum DC resistance of 300 milliohms. The component supports a rated current of 600 mA and operates within a temperature range of -40°C to +85°C. Housed in a compact 0402 (1005 Metric) surface-mount package with dimensions of 1.00mm x 0.50mm, it is designed for EMI suppression applications.

Feature Summary

• Provides effective electromagnetic interference suppression through high impedance characteristics at target frequencies
• Utilizes multilayer ceramic construction for reliable performance in compact surface-mount designs
• Supports high current handling capabilities suitable for power line filtering applications

Applications

• Power line filtering in portable electronic devices
• EMI suppression on data lines in consumer electronics
• Noise reduction in automotive infotainment systems

Procurement Notes

Verify the specific suffix against official Eaton documentation to confirm impedance and current ratings. Ensure the ordering code matches the required 0402 package variant. Confirm RoHS compliance status if restricted substances are mandated for the end product. Cross-reference the manufacturer part number with authorized distributor catalogs to avoid counterfeit components.

Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for noise attenuation. The 600 mA current rating must exceed the maximum operating current of the protected circuit. The 0402 footprint dictates board space constraints. Verify that the DC resistance meets voltage drop requirements for the specific power rail.

Part Context

This component belongs to the MFB series of multilayer ferrite beads from Eaton Electronics Division. These chips are engineered for high-density PCB layouts where space is limited. The series offers various impedance values and current ratings to address different frequency and power requirements across industrial and consumer markets.

Replacement Considerations

Direct substitutes include other Eaton MFB series parts with matching 300 Ohm impedance and 0402 packaging. Verify equivalent current ratings and DC resistance before substitution. Alternative manufacturers may offer similar specifications but require thermal and mechanical compatibility checks.
