MMZ1608Y121BTA00

Overview

The TDK MMZ1608Y121BTA00 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 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 200 mOhms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Optimized for high-speed signal lines to suppress electromagnetic interference
• Low direct current resistance design compatible with moderate current loads
• Commercial grade construction suitable for general electronic equipment

Applications

• High-speed digital signal line filtering
• General commercial electronic circuits
• Power supply noise suppression in low-current paths

Procurement Notes

Verify the specific suffix BTA00 against the official TDK datasheet to confirm packaging type and compliance status. Ensure the selected variant matches the required impedance and current ratings for the target circuit. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm RoHS and halogen-free compliance if required by the end product specifications.

Selection Notes

Select this component when a 0603 footprint is required for signal integrity management. The 120 Ohm impedance at 100 MHz targets common noise frequencies in digital systems. The 500 mA rating allows use in power delivery lines where minimal voltage drop is critical due to the low DC resistance. Consider the -55°C to +125°C range for broad environmental compatibility.

Part Context
