MMZ1005Y400CT000

Overview

The MMZ1005Y400CT000 is a ferrite chip bead from the TDK MMZ series, designed for surface-mount technology in a 0402 (1005 metric) package. It provides an impedance of 40 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 550 mA and has a maximum DC resistance of 100 mOhms. It operates within a temperature range of -55°C to +125°C. Physical dimensions are 1 mm length, 0.5 mm width, and 0.5 mm height.

Feature Summary

• Designed for high-speed signal line filtering applications
• Compact 0402 surface-mount form factor

Applications

• High-speed signal line noise suppression
• General-purpose EMC countermeasures

Procurement Notes

Verify the specific suffix CT000 against official TDK documentation to confirm packaging details such as cut tape or reel configuration. Ensure the selected variant matches the required impedance and current ratings for the target circuit design before procurement.

Selection Notes

Select this component when a compact ferrite bead is required for high-speed signals with a 40 Ohm impedance at 100 MHz. The 550 mA current rating suits low-power digital lines. Verify that the 0402 footprint fits the PCB layout constraints and that the operating temperature range meets environmental requirements.

Part Context

This part belongs to the TDK MMZ series of ferrite chip beads. These components are engineered for electromagnetic interference suppression in electronic circuits. The MMZ series offers various impedance values and current ratings in standard surface-mount packages to accommodate diverse design needs.

Replacement Considerations

Consult official TDK substitution guides for verified equivalents. Cross-reference impedance, current rating, and package dimensions when evaluating alternative parts.
