MCZ1210AD102T

Common Mode Chokes Overview

The MCZ1210AD102T is a two-line common mode choke manufactured by TDK Corporation, designed for surface mount applications. It features an impedance of 1 kOhms at a test frequency of 100 MHz and supports a maximum DC current of 50 mA. The component has a maximum DC resistance (DCR) of 750 mOhms and operates within a temperature range of -40°C to +85°C. Housed in a 0504 (1210 metric) package with four leads, its physical dimensions are 1.25 mm in length, 1.00 mm in width, and a maximum height of 0.60 mm. This part is classified as a signal line filter.

• General purpose signal line noise suppression

Common Mode Chokes Procurement Notes

Verify the component status before integration, as this specific part number is marked as Not Recommended for New Designs (NRND). Confirm that existing inventory or last-time buy options align with production requirements. Ensure compatibility with the 0504 package dimensions during PCB layout finalization. Cross-reference datasheet specifications against current design constraints to avoid obsolescence risks in future manufacturing cycles.

Common Mode Chokes Selection Notes

Select this component when designing for low-current signal lines requiring high impedance at 100 MHz. The 50 mA rating suits sensitive data interfaces rather than power delivery paths. Consider the 750 mOhm DCR impact on signal integrity. Evaluate alternative parts from the same series if higher current handling or different impedance values are required for the target application environment.

Common Mode Chokes Part Context

This component belongs to the TDK MCZ series of chip beads and common mode chokes. These devices are engineered for suppressing electromagnetic interference in high-speed digital and analog signal paths. The MCZ1210AD variant specifically targets consumer electronics interfaces, offering a balance between noise attenuation and minimal signal distortion in space-constrained mobile and portable devices.

Common Mode Chokes Replacement Considerations

Publicly confirmed substitute part numbers include MMZ1005Y102CT000 from TDK and EXC-24CB102U from Panasonic Industry. Verify pinout compatibility and impedance tolerance matches before substitution.
