MPZ1005S121ETD25

Overview

The TDK MPZ1005S121ETD25 is a single-line ferrite bead chip designed for power line noise suppression in the GHz frequency range. It features an impedance of 120 ohms at 100 MHz and supports a maximum rated current of 1500 mA with a maximum DC resistance of 0.12 ohms. The component utilizes a 0402 (1005 metric) surface-mount package, measuring 1.0 mm in length, 0.5 mm in width, and 0.5 mm in height. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 automotive qualification.

Feature Summary

• High wide-band impedance characteristics optimized for GHz noise suppression on power lines
• Automotive-grade reliability certified under the AEC-Q200 standard
• Compact 0402 surface-mount footprint suitable for space-constrained PCB layouts

Applications

• Automotive electronic systems requiring AEC-Q200 compliance
• Power supply input filtering for high-current digital circuits
• Noise suppression on data lines in GHz frequency applications

Procurement Notes

Verify the specific suffix 'ETD25' against official TDK documentation to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the selected variant matches the required impedance tolerance and current rating for the target power line application. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability.

Selection Notes

Select this component when designing power filters for automotive or industrial applications requiring high current handling up to 1.5A. The 0402 package size is appropriate for dense surface-mount assemblies. Consider the 120-ohm impedance at 100 MHz to ensure effective attenuation of high-frequency electromagnetic interference without excessive voltage drop across the low DC resistance.

Part Context

This component belongs to the TDK MPZ-E series of ferrite beads, specifically engineered for power line noise suppression. The MPZ series distinguishes itself from signal line variants by offering higher current ratings and optimized impedance profiles for broadband GHz noise reduction. The 1005 metric case size represents a compact form factor balancing performance with board space efficiency.

Replacement Considerations

Consult official TDK substitution guides for equivalent parts within the MPZ or MMZ series that match the 0402 footprint, 120-ohm impedance, and 1.5A current rating. Verify that any alternative maintains AEC-Q200 certification if automotive usage is required.
