MFBW1V1608-500-R

Overview

The Eaton MFBW1V1608-500-R is a multilayer ferrite chip bead designed for electromagnetic interference (EMI) suppression in surface-mount applications. It 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 50 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 1 A and has a maximum DC resistance of 120 mOhms. The device operates within a temperature range of -40°C to +85°C and is shielded.

Feature Summary

• Multilayer construction for effective EMI suppression
• Shielded design to contain magnetic fields
• Surface-mount compatibility for automated assembly

Applications

• Power line filtering in portable electronics
• Signal integrity protection in high-speed data lines
• Noise suppression in automotive electronic modules

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official Eaton datasheet prior to procurement, as manufacturing batches may exhibit variations within specified limits. Confirm that the 0603 package footprint aligns with the target PCB layout. Ensure compliance with RoHS3 standards if required by the end-product regulations. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a low-impedance ferrite solution is required for 1 A power rails or sensitive signal lines in compact designs. The 50 Ohm impedance at 100 MHz makes it suitable for suppressing lower-frequency noise compared to higher-impedance variants. Consider the 120 mOhms DCR to ensure minimal voltage drop across the circuit path. The 0603 size offers a balance between current handling capability and board space efficiency.

Part Context

This part belongs to the Eaton MFBW1V series of multilayer ferrite beads. The series utilizes proprietary ceramic materials to provide stable impedance characteristics over a wide frequency range. The MFBW1V1608 variant specifically targets applications requiring robust performance in small form factors, offering reliable shielding and thermal stability for modern electronic systems.

Replacement Considerations

Direct substitutes include the MFBM1V1608-500-R from the same manufacturer family, which shares the 0603 footprint but may differ in current rating and DC resistance specifications. Verify electrical parameters before substitution.
