MMZ0603D121CT

Overview

The TDK MMZ0603D121CT is a single-line ferrite bead in the MMZ series, housed in a 0201 (0603 metric) surface-mount package. It provides an impedance of 120 Ohms at 100 MHz with a maximum DC resistance of 1.4 Ohms and a current rating of 100 mA. The component operates within a temperature range of -55°C to +125°C and features a 25% impedance tolerance.

Feature Summary

• Provides electromagnetic interference suppression for high-speed signal lines
• Designed for compact surface-mount applications requiring minimal footprint
• Constructed with lead-free materials compliant with RoHS directives

Applications

• High-speed data line filtering
• Clock circuit noise suppression
• General-purpose EMI suppression in portable devices

Procurement Notes

Verify the specific suffix 'CT' against official TDK documentation to confirm packaging details and exact electrical tolerances. Ensure the selected variant matches the required current rating and impedance specifications for the target application circuit.

Selection Notes

Select this component when space constraints necessitate a 0201 package size. Confirm that the 100 mA current rating meets the circuit's operational requirements and that the 1.4 Ohm DC resistance does not cause unacceptable voltage drop.

Part Context

This part belongs to the TDK MMZ series of chip ferrite beads, designed for general-purpose EMI suppression. The MMZ series offers various impedance values and current ratings across multiple standard package sizes to support diverse electronic design needs.

Replacement Considerations

Cross-reference with other TDK MMZ series parts in the 0201 package. Verify that any substitute maintains identical impedance characteristics at 100 MHz and meets or exceeds the 100 mA current handling capability.
