MFBW1V1608-122-R

Overview

The MFBW1V1608-122-R is a multilayer ferrite chip bead manufactured by Eaton Electronics, designed for surface-mount technology (SMT) 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 1.2 kOhms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 650 mOhms. The device is shielded and available in reel, cut tape, and MouseReel packaging formats.

Feature Summary

• Multilayer construction for effective electromagnetic interference suppression
• Shielded design to minimize external magnetic field interaction
• Surface-mount compatibility for automated PCB assembly processes

Applications

• EMI suppression in high-speed digital circuits
• Power line filtering for sensitive electronic components
• Signal integrity enhancement in communication interfaces

Procurement Notes

Verify the specific manufacturer part number against official Eaton Electronics documentation to ensure authenticity and correct specifications. Confirm RoHS compliance status through the latest datasheet or certification documents provided by the supplier. Check for any updated environmental declarations or material safety data sheets required for your manufacturing region. Ensure that the ordering suffix matches the desired packaging format, such as reel or cut tape, as indicated in the official product catalog.

Selection Notes

Select this component when shielding is required to prevent magnetic coupling with adjacent circuitry. The 500 mA current rating suits moderate power applications, while the 1.2 kOhm impedance at 100 MHz targets specific noise frequencies. Consider the 0603 footprint constraints and verify that the 650 mOhms DC resistance meets the voltage drop requirements of the target circuit. Evaluate thermal performance within the specified -40°C to +85°C operating range.

Part Context

This ferrite bead belongs to the MFBW1V series from Eaton Electronics, which focuses on multilayer chip beads for EMI suppression. The series utilizes advanced ceramic materials to provide stable impedance characteristics across varying temperatures. The MFBW1V1608-122-R specifically addresses the need for compact, shielded solutions in space-constrained modern electronics designs.

Replacement Considerations

Consult Eaton Electronics official substitution guides for verified alternative part numbers within the MFBW1V series or other compatible ferrite bead families. Ensure any substitute maintains identical impedance, current rating, and physical dimensions.
