MMZ1608R301ATA00

Overview

The TDK MMZ1608R301ATA00 is a surface-mount ferrite chip bead from the MMZ series, designed for signal line applications. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 300 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 250 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high impedance attenuation for noise suppression on signal lines
• Compact 0603 surface-mount footprint for space-constrained designs
• Capable of handling continuous DC currents up to 500 mA

Applications

• Signal line noise filtering in electronic circuits
• High-frequency interference suppression in consumer electronics
• EMI reduction in portable devices

Procurement Notes

Verify the complete part number including the suffix ATA00 to ensure correct packaging and specifications. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Check for any recent manufacturing changes or obsolescence notices associated with the MMZ series. Ensure compatibility with standard SMD reflow soldering profiles used in PCB assembly processes.

Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for signal integrity management. The 0603 package size suits boards with limited real estate. Consider the 500 mA current rating to prevent saturation during normal operation. Evaluate the low DC resistance to minimize voltage drop across the component in sensitive signal paths.

Part Context

This ferrite bead belongs to TDK's MMZ series, which offers various impedance values and current ratings in standardized packages. The MMZ1608R301ATA00 specifically targets general-purpose signal line protection. It complements other passive components by providing targeted high-frequency damping without significantly affecting the DC characteristics of the circuit.
