MFBW1V3216-700-R

Overview

The MFBW1V3216-700-R is a multilayer ferrite chip bead from the Eaton Electronics MFBW1V series, designed for surface-mount technology (SMT) applications. It features a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 0.9 mm height. The component provides an impedance of 70 Ohms at a test frequency of 100 MHz, with a tolerance of ±25%. It supports a maximum DC current of 3.0 A and has a maximum DC resistance of 70 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 in compact SMT layouts
• Shielded design to minimize electromagnetic interference coupling
• High current handling capability suitable for power line filtering

Applications

• EMI suppression on high-current signal lines
• Power supply input/output filtering
• Digital circuit noise reduction

Procurement Notes

Verify the specific impedance value and current rating against the latest official datasheet before integration. Confirm that the 1206 package dimensions align with the PCB footprint requirements. Ensure the operating temperature range meets the environmental conditions of the final assembly. Check RoHS compliance status if required by regulatory standards.

Selection Notes

Select this component when a 70 Ohm impedance at 100 MHz is required for noise suppression in circuits carrying up to 3 Amperes. The 1206 package offers a balance between current capacity and board space. Consider the low DC resistance to minimize voltage drop and power loss in the signal path. Evaluate the thermal performance under continuous load conditions.

Part Context

This part belongs to the Eaton Electronics MFBW1V series of multilayer ferrite beads. These components are engineered for general-purpose EMI suppression in electronic equipment. The series utilizes advanced ceramic materials to provide stable impedance characteristics over a wide frequency range. They are commonly used in consumer electronics, industrial controls, and telecommunications devices.

Replacement Considerations

Compatible substitutes include other 1206 ferrite beads with similar impedance and current ratings, such as the MFBW1V3216-121-R or MFBW1V3216-221-R, provided their impedance values match the specific noise frequency requirements. Verify pin compatibility and thermal characteristics before substitution.
