MA3216-201M4

Chip Ferrite Bead Overview

The MA3216-201M4 is a ferrite bead array manufactured by Bourns Inc., designed for surface-mount technology applications. It features a 1206 (3216 metric) package with four independent lines, providing compact noise suppression in multi-conductor circuits. The component exhibits an impedance of 200 Ohms at 100 MHz and supports a maximum current rating of 100 mA. Its low DC resistance of 300 mOhm ensures minimal signal attenuation while effectively attenuating high-frequency electromagnetic interference across multiple channels simultaneously.

Chip Ferrite Bead Feature Summary

• Four independent filtering lines integrated into a single compact footprint
• High impedance performance at 100 MHz for effective noise suppression
• Low DC resistance to minimize signal loss in data lines

Chip Ferrite Bead Applications

• Noise filtering for USB data lines
• Signal integrity protection in high-speed digital interfaces
• Electromagnetic interference suppression in portable electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific impedance tolerance and current ratings against the official Bourns datasheet before integration. Confirm that the 1206 package dimensions align with the target PCB land pattern. Ensure the selected variant matches the required four-line configuration for the specific circuit design needs.

Chip Ferrite Bead Selection Notes

Select this component when multi-channel noise suppression is required within space-constrained areas. The four-line architecture simplifies layout compared to discrete beads. Evaluate the 100 mA current limit to ensure it meets the operational requirements of the protected signals without saturation.

Chip Ferrite Bead Part Context

This part belongs to Bourns' MA series of ferrite chip bead arrays. These components are engineered for high-density electronics where multiple signal lines require simultaneous filtering. The series offers various impedance values and line counts to accommodate diverse interface standards and noise profiles.

Chip Ferrite Bead Replacement Considerations

Check for direct substitutes within the MA3216 series offering identical 200 Ohm impedance and four-line topology. Verify pin compatibility and physical dimensions to ensure drop-in replacement capability without PCB redesign.
