MMZ1005D241CTD25

Overview

The MMZ1005D241CTD25 is a single-line ferrite chip bead from the TDK MMZ Auto series, designed for signal line noise suppression. It features an impedance of 240 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 200 mA. The component has a maximum DC resistance of 600 mOhms with a 25% tolerance. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards. The physical dimensions are 1.0 mm in length, 0.5 mm in width, and 0.5 mm in height, housed in a standard 0402 (1005 metric) surface-mount package.

Feature Summary

• Provides effective noise suppression over a wide frequency range using specialized ferrite materials.
• Automotive-grade reliability certified under AEC-Q200 standards for harsh environment durability.
• Miniaturized 0402 footprint allows for high-density circuit board layouts without preferred orientation requirements.

Applications

• Automotive electronic systems requiring EMI/RFI filtering
• High-speed digital signal line protection
• Portable consumer electronics with space constraints

Procurement Notes

Verify the specific suffix 'CTD25' against official TDK documentation to confirm tape and reel specifications. Ensure the selected variant matches the required impedance and current ratings for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm authenticity and availability status before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require robust noise attenuation in compact spaces. The 240 Ohm impedance value targets specific interference frequencies around 100 MHz. Verify that the 200 mA current rating exceeds the maximum operating current of the protected signal line to prevent saturation or excessive heating during normal operation.

Part Context

This component belongs to the MMZ Auto series, which utilizes TDK's proprietary ferrite technology for efficient noise removal. The series includes various sizes and material types optimized for different frequency bands and current levels. The MMZ1005D241CTD25 specifically addresses the need for small-form-factor filtering solutions in modern electronic assemblies.

Replacement Considerations

Consult TDK datasheets for direct substitutes within the MMZ1005 series with matching 240 Ohm impedance. Verify that any alternative components maintain identical AEC-Q200 certification and thermal performance characteristics to ensure system compatibility.
