MFBW1V1005-190-R

Overview

The MFBW1V1005-190-R is a single-line ferrite bead from the Eaton MFBW1V1005 series, designed for EMI suppression in surface-mount applications. It features a 0402 (1005 metric) package with dimensions of 1.00mm x 0.50mm and a maximum height of 0.65mm. The component provides an impedance of 19 ohms at 100 MHz with a tolerance of ±25%. It supports a rated current of 700 mA and has a maximum DC resistance of 60 milliohms. Operating temperature ranges from -40°C to +85°C.

Feature Summary

• Provides effective electromagnetic interference suppression through high impedance characteristics at target frequencies
• Utilizes a compact 0402 surface-mount footprint to optimize board space utilization
• Engineered for high-current handling capabilities suitable for power line filtering applications

Applications

• EMI suppression on data lines in portable electronic devices
• Filtering noise on power supply rails in consumer electronics
• Signal integrity enhancement in high-speed digital circuits

Procurement Notes

Verify the specific suffix '190' confirms the 19 Ohm impedance value, as other suffixes in the MFBW1V1005 series denote different impedance ratings. Confirm RoHS3 compliance status if required by your manufacturing standards. Ensure the ordering quantity aligns with the manufacturer's standard packaging specifications to avoid additional handling fees or minimum order constraints.

Selection Notes

Select this component when a low-profile 0402 ferrite bead is required for noise attenuation in space-constrained designs. The 700 mA current rating makes it suitable for moderate current paths where minimal DC resistance is critical to prevent voltage drop. Compare impedance curves against the specific noise frequency spectrum to ensure adequate attenuation at the target frequency range.

Part Context

This part belongs to the Eaton MFBW1V1005 series of multilayer ferrite chip beads. These components are engineered for general-purpose EMI suppression in various electronic systems. The series offers multiple impedance options within the same physical package, allowing designers to maintain consistent board layouts while adjusting filtering characteristics for different circuit requirements.

Replacement Considerations

Cross-reference with other 0402 ferrite beads offering similar 19 Ohm impedance at 100 MHz and comparable current ratings. Verify that alternative components match the physical dimensions and terminal configurations to ensure compatibility with existing footprints.
