MCZ1210DH120CPTD25

Common Mode Chokes Overview

The MCZ1210DH120CPTD25 is a surface-mount common mode filter manufactured by TDK Corporation. It features an impedance of 12 Ohms with a tolerance of 5% at a test frequency of 100 MHz. The component supports a maximum DC current of 100 mA and operates within a voltage rating of 5 VDC. Designed for automotive applications, it holds AEC-Q200 qualification. The device utilizes a 1210 metric package (0404) with dimensions of 1.25 mm in length, 1 mm in width, and 0.5 mm in height. It functions as a single-channel filter intended to suppress common mode noise while preserving signal integrity in high-speed differential transmission lines.

• Suppresses common mode noise without affecting high-speed differential transmission signals
• AEC-Q200 qualified for automotive reliability standards
• Optimized for ultra-high speed differential transmission lines

Common Mode Chokes Applications

• HDMI interfaces
• USB 3.0 connections
• Automotive electronic systems

Common Mode Chokes Procurement Notes

Verify the specific suffix 'D25' confirms the -40°C to +105°C operating temperature range required for your design. Ensure the PCB footprint matches the 1210 metric (0404) dimensions provided in the datasheet. Confirm that the 100 mA current rating aligns with the target circuit's operational requirements before finalizing procurement.

Common Mode Chokes Selection Notes

Select this component when designing circuits requiring noise suppression for high-speed differential data lines such as HDMI or USB 3.0. The choice is driven by the need for AEC-Q200 compliance in automotive environments. Consider the 12 Ohm impedance value relative to the target frequency band to ensure effective filtering performance without degrading the desired signal quality.

Common Mode Chokes Part Context

This part belongs to the MCZ-DH series of common mode filters from TDK. The series is engineered specifically for suppressing electromagnetic interference in high-frequency applications. The DH variant denotes specific construction characteristics suitable for maintaining signal integrity in differential pairs while providing necessary attenuation for common mode disturbances.

Common Mode Chokes Replacement Considerations

The MCZ1210DH120CPTA0G serves as a verified alternative within the same series. Note that the CPTA0G suffix indicates a different operating temperature range (-40°C to +85°C) compared to the CPTD25 model. Verify thermal requirements before substitution.
