MMZ1608B121CTAH0

Overview

The MMZ1608B121CTAH0 is a surface-mount ferrite bead from the TDK MMZ series, designed for general signal line noise suppression. It features an impedance of 120 Ohms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 600 mA and exhibits a maximum DC resistance of 150 milliohms. Housed in a compact 0603 (1608 metric) package measuring 1.6 mm by 0.8 mm, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective attenuation of high-frequency electromagnetic interference on single signal lines
• Maintains stable electrical characteristics across a wide industrial temperature spectrum
• Utilizes a miniature footprint suitable for dense surface-mount PCB layouts

Applications

• High-speed digital signal line noise filtering
• General-purpose EMI suppression in consumer electronics
• Power integrity management in compact mobile devices

Procurement Notes

Verify the complete part number against official TDK documentation to ensure correct suffix alignment. Confirm that the specific ordering code matches the required impedance and current ratings for your design. Cross-reference the datasheet revision history to account for any manufacturing changes or allocation updates prior to finalizing procurement orders.

Selection Notes

Select this component when a 120 Ohm impedance at 100 MHz is required for signal integrity. Ensure the circuit's operating current remains below the 600 mA limit to prevent saturation. The 0603 package size offers a balance between performance and board space efficiency for standard surface-mount assembly processes.

Part Context

This ferrite bead belongs to the MMZ series, which focuses on small-size components for preventing radiated noise from high-speed signal lines. The MMZ1608B121CTAH0 variant specifically targets applications requiring reliable noise suppression in limited spaces while maintaining low insertion loss for the desired frequency band.

Replacement Considerations

Consult the official TDK MMZ Series Brief for confirmed substitute part numbers. Verify that any alternative component matches the 120 Ohm impedance, 600 mA current rating, and 0603 package dimensions to ensure mechanical and electrical compatibility.
