MMZ1608F121BTA00

Overview

The TDK MMZ1608F121BTA00 is a surface-mount ferrite bead from the MMZ series, designed for signal line applications. It features a 0603 (1608 metric) package with dimensions of 1.6mm length, 0.8mm width, and 0.8mm height. The component provides an impedance of 120 Ohms at 100 MHz with a maximum DC resistance of 750 milliohms. It supports a rated current of 200mA and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Designed specifically for signal line filtering applications
• Offers low direct current resistance for compatibility with specific current requirements
• Constructed in a compact 0603 surface-mount package

Applications

• Signal line noise suppression
• Electronic circuit filtering

Procurement Notes

Verify the specific suffix 'F' against official TDK documentation to confirm the 200mA rating and 750mOhm DC resistance, as other suffixes like 'Q' or 'Y' indicate different electrical characteristics. Ensure the ordering code matches the exact impedance and current specifications required for the target signal line application to avoid performance mismatches.

Selection Notes

Select this component when a 120 Ohm impedance at 100 MHz is required for signal integrity. The 200mA current rating distinguishes it from higher-current variants in the same package size. Consider the 750mOhm DC resistance impact on signal voltage levels. Verify that the 0603 footprint aligns with the PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the TDK MMZ series of chip ferrite beads. The series utilizes ferrite materials to suppress electromagnetic interference in electronic circuits. The MMZ1608F variant specifically targets applications requiring lower current handling compared to the standard MMZ1608Q or MMZ1608Y models, offering a distinct balance between impedance and DC resistance.
