MMZ1608S121ATA00

Overview

The MMZ1608S121ATA00 is a surface-mount ferrite chip bead from the TDK MMZ series, designed for general 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 120 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 150 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Designed specifically for filtering noise on general signal lines
• Utilizes a compact 0603 surface-mount footprint for space-constrained layouts
• Provides high impedance characteristics at 100 MHz to suppress electromagnetic interference

Applications

• General signal line noise suppression
• High-speed digital circuit filtering
• Data bus protection in electronic assemblies

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. Cross-reference the specific impedance and current ratings against the target application requirements to prevent performance mismatches or saturation issues during operation.

Selection Notes

Select this component when signal line filtering is required in a 0603 package. Ensure the operating current does not exceed 500 mA to maintain effective impedance characteristics. Consider the 120 Ohm impedance value at 100 MHz relative to the noise frequencies present in the specific circuit design. Verify thermal stability requirements align with the -55°C to +125°C operational range.

Part Context

This component belongs to the TDK MMZ series of ferrite chip beads. The MMZ series is engineered for use in general signal lines where moderate noise suppression is necessary. It complements other components in power management and data transmission circuits by providing targeted high-frequency attenuation without significantly affecting the desired signal integrity.
