MFBW1V3216-152-R

Overview

The MFBW1V3216-152-R is a single-line multilayer chip ferrite bead manufactured by Eaton Electronics Division. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.20mm x 1.60mm x 0.9mm maximum height. The component provides an impedance of 1.5 kOhms at 100 MHz and supports a maximum DC current rating of 500mA. Its maximum DC resistance (DCR) is specified at 450 milliohms. The device operates within a temperature range of -40°C to +85°C and is supplied in tape and reel packaging.

Feature Summary

• Multilayer construction for compact high-frequency noise suppression
• Shielded design to minimize electromagnetic interference
• Surface mount termination for automated PCB assembly

Applications

• High-frequency noise filtering in electronic circuits
• Power line decoupling for sensitive components
• Signal integrity enhancement in data transmission lines

Procurement Notes

Verify the specific impedance tolerance and DCR values against the official Eaton datasheet prior to integration, as manufacturing batches may exhibit slight variations. Confirm that the 1206 footprint matches the target PCB layout constraints. Ensure the selected supplier provides genuine Eaton Electronics Division products to guarantee compliance with RoHS3 standards and operational reliability under specified thermal conditions.

Selection Notes

Select this component when circuit requirements demand 1.5 kOhms impedance at 100 MHz with a 500mA current capacity. The 1206 package size suits applications with moderate space constraints compared to smaller footprints. Evaluate the 450 milliohm DCR impact on power loss in low-voltage supply rails. Consider the -40°C to +85°C operating range for standard commercial or industrial environments requiring reliable EMI attenuation without excessive heat generation.

Part Context

This part belongs to the MFBW1V series of multilayer ferrite beads from Eaton Electronics. The series offers various impedance and current ratings within the 1206 package format. These components are designed for general-purpose EMI suppression in consumer electronics, telecommunications, and computing hardware where space efficiency and consistent performance are prioritized over extreme environmental ruggedness.

Replacement Considerations

Compatible substitutes include other 1206 ferrite beads with similar 1.5 kOhm @ 100 MHz impedance and 500mA current ratings. Verify pin compatibility and physical dimensions before substitution. Alternative parts must meet equivalent DCR and thermal specifications to maintain circuit performance.
