MMZ1608R300ATA00

Overview

The MMZ1608R300ATA00 is a ferrite chip bead from the TDK MMZ series, designed for general signal line applications. It features 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 30 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 1.5 A and has a maximum DC resistance of 50 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides electromagnetic interference suppression for general signal lines through high-impedance characteristics at target frequencies.
• Utilizes a compact 0603 surface-mount footprint to facilitate automated assembly and space-constrained PCB layouts.

Applications

• General signal line noise suppression
• High-speed data interface filtering
• Clock signal integrity maintenance

Procurement Notes

Verify the specific suffix ATA00 against the manufacturer's latest documentation to confirm compliance with current RoHS directives and halogen-free status. Ensure that the selected packaging format aligns with available reeling or cut-tape infrastructure. Cross-reference the part number with official TDK databases to validate active status and avoid obsolete inventory risks during procurement.

Selection Notes

Select this component when signal line filtering requires a 30 Ohm impedance level at 100 MHz. The 1.5 A current rating suits moderate-power signal paths without excessive thermal rise. The 0603 package offers a balance between parasitic inductance reduction and board space efficiency compared to larger footprints.

Part Context

This part belongs to the TDK MMZ series of ferrite beads, which are widely used for EMI suppression in electronic circuits. The MMZ series covers various impedance values and current ratings across multiple package sizes, providing standardized solutions for noise control in consumer electronics and industrial equipment.

Replacement Considerations

MMZ1608R300ATD25 is a documented alternative within the same series offering AEC-Q200 qualification for automotive applications while maintaining identical electrical parameters.
