MMZ1608S121CTAH0

Overview

The TDK MMZ1608S121CTAH0 is a surface-mount ferrite chip bead designed for signal line applications. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.6 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 operating temperature range spans from -55°C to +125°C.

Feature Summary

• Designed specifically for signal line filtering applications
• Compact 0603 surface-mount form factor for space-constrained layouts
• Capable of handling up to 500 mA DC current without saturation

Applications

• Signal line noise suppression in electronic circuits
• High-frequency interference filtering for data lines

Procurement Notes

Verify the Not Recommended for New Design (NRND) status before initiating new projects. Confirm RoHS compliance details through official documentation. Ensure the specific suffix matches required packaging options such as cut tape or reel. Validate that the 120 Ohm impedance at 100 MHz aligns with target EMI suppression requirements.

Selection Notes

Select this component when a 0603 footprint is required for signal integrity management. The 500 mA rating suits moderate current signal paths. Compare against automotive-grade alternatives if AEC-Q200 certification is mandatory. Verify that the 150 mOhm DCR meets voltage drop constraints in the specific circuit design.

Part Context

This part belongs to the TDK MMZ series of ferrite chip beads. It utilizes monolithic construction for reliability. The 0603 size is standard for general-purpose electronics assembly. It serves as a passive component for electromagnetic interference reduction in consumer and industrial devices.

Replacement Considerations

MMZ1608S121ATA00 is listed as a recommended alternate part number.
