MFBW1V1608-190-R

Overview

The MFBW1V1608-190-R is a multilayer chip ferrite bead manufactured by Eaton Electronics. It features a shielded design in a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 19 Ohms at a test frequency of 100 MHz, with a tolerance range of 12 to 25 Ohms. It supports a maximum DC current of 1.0 A and has a maximum DC resistance of 80 mOhms. The device operates within a temperature range of -40°C to +85°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling between adjacent circuits
• Multilayer chip architecture enables compact footprint integration for high-density PCB layouts
• High current handling capability suitable for power line noise suppression applications

Applications

• Noise suppression on power supply lines in portable electronic devices
• EMI filtering in mobile communication equipment
• Signal integrity enhancement in consumer electronics

Procurement Notes

Verify the specific suffix 'R' indicates reel packaging configuration when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure the selected distributor provides valid traceability records. Cross-reference the Eaton part number with authorized channel listings to avoid counterfeit components. Validate that the 0603 package size matches the target PCB land pattern specifications.

Selection Notes

Select this component when a 19 Ohm impedance at 100 MHz is required for noise attenuation. The 1.0 A current rating determines suitability for low-to-medium power circuits. The shielded type is preferred over unshielded variants to prevent magnetic field interaction with nearby sensitive components. Consider the 80 mOhms DC resistance impact on voltage drop in power delivery networks. The 0603 form factor dictates available board space constraints.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics. The series offers various impedance values and current ratings within the same 0603 footprint. The 'W' designation typically distinguishes specific material characteristics or current capabilities within the broader MFBM family. These components are designed for general-purpose EMI suppression in modern electronic assemblies.

Replacement Considerations

Direct substitutes include other 0603 shielded ferrite beads with 19 Ohms impedance and similar current ratings. Verify pin compatibility and thermal performance before substitution. Check if alternative manufacturers offer equivalent shielding effectiveness and impedance-frequency curves.
