MMZ1005S102CTD25

Overview

The TDK MMZ1005S102CTD25 is a ferrite chip bead in the MMZ series, designed for signal line applications. It features a 0402 (1005 metric) SMD package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 1000 ohms at a test frequency of 100 MHz with a 25% tolerance. It supports a maximum DC current of 200 mA and has a maximum DC resistance of 750 mOhms. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• Compact 0402 surface-mount footprint for space-constrained designs
• High impedance characteristic for effective noise suppression on signal lines

Applications

• Automotive electronic systems requiring AEC-Q200 compliance
• Signal line noise suppression in compact devices
• General purpose EMI filtering in consumer electronics

Procurement Notes

Verify the specific suffix CTD25 against official TDK documentation to confirm packaging type and tape-and-reel specifications. Ensure the selected variant matches the required impedance and current ratings for the target application circuit. Cross-reference the part number with authorized distributors to confirm authenticity and availability status prior to ordering.

Selection Notes

Select this component when high impedance is required for signal integrity protection in small form factors. The 200 mA current rating suits low-power signal lines rather than power rails. Consider the 750 mOhms DC resistance impact on voltage drop if placed in sensitive analog paths. Verify thermal performance within the -55°C to +125°C operating range for the intended environment.

Part Context

This part belongs to the TDK MMZ series of ferrite beads, which are widely used for electromagnetic interference suppression. The MMZ series offers various impedance values and current ratings in standard metric packages. The MMZ1005S102CTD25 specifically targets applications needing robust noise filtering in a minimal 0402 footprint while meeting automotive quality requirements.

Replacement Considerations

Check for direct substitutes within the MMZ series such as MMZ1005S102HT000 or MMZ1005S182ETD25 based on impedance and current needs. Verify that any replacement maintains the same 0402 package dimensions and AEC-Q200 qualification if automotive use is required. Confirm equivalent DC resistance and saturation current characteristics before substitution.
