MMZ1005Y121CT000

Overview

The MMZ1005Y121CT000 is a single-line ferrite chip bead from the TDK MMZ series, designed for general signal line applications. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm length, 0.50mm width, and 0.55mm maximum 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 400 mA and has a maximum DC resistance of 180 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Designed for high-speed signal line filtering in compact electronic circuits.
• Utilizes a standard 0402 surface-mount footprint for automated assembly compatibility.

Applications

• General signal line noise suppression
• High-speed digital circuit filtering

Procurement Notes

Verify the specific suffix CT000 against the official TDK datasheet to confirm commercial grade classification and packaging details. Ensure the ordering information matches the required impedance and current ratings for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select this component when a low-profile ferrite bead is required for high-speed signal integrity management. The 0402 package size suits dense PCB layouts where space is limited. The 400 mA current rating and 120 Ohm impedance at 100 MHz define its suitability for specific data lines. Confirm that the commercial temperature range meets the environmental requirements of the final product.

Part Context

This component belongs to the TDK MMZ series of ferrite beads, which are widely used for electromagnetic interference suppression. The MMZ1005Y121CT000 specifically targets general-purpose signal lines, offering a balance between physical size and electrical performance. It is distinct from automotive-grade variants like the MMZ Auto series, which carry AEC-Q200 certification.
