MMZ1005A102ET000

Overview

The MMZ1005A102ET000 is a ferrite chip bead from the TDK MMZ-E series, designed for noise suppression in high-speed signal lines. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 1 kOhms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 250 mA and has a maximum DC resistance of 1.2 Ohms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Engineered for high-speed signal line applications requiring effective noise countermeasures
• Provides high impedance across a wide frequency band for broad-spectrum interference suppression

Applications

• High-speed signal line noise suppression
• General electronic equipment EMI filtering
• Data processing circuit protection

Procurement Notes

Verify the specific suffix ET000 against project requirements to ensure compatibility with reel or cut tape packaging preferences. Confirm that the 0402 footprint aligns with the PCB layout. Check RoHS compliance status if restricted substances are mandated. Ensure the 250 mA current rating meets the operational load without excessive thermal rise. Validate the 1 kOhm impedance specification matches the target noise frequency spectrum.

Selection Notes

Select this component when space constraints require a 0402 package size. Choose based on the need for 1 kOhm impedance at 100 MHz for signal integrity management. Consider the 250 mA current handling capability for power efficiency. Evaluate the -55°C to +125°C temperature range for environmental suitability. Compare against other MMZ-E variants if different impedance or current ratings are needed.

Part Context

This part belongs to the TDK MMZ-E series of ferrite beads, which are optimized for general-purpose and high-speed digital circuits. The series offers various impedance values and current ratings within standard metric footprints. The MMZ1005A102ET000 specifically targets compact designs requiring reliable EMI reduction in dense PCB layouts.

Replacement Considerations

Cross-reference with MMZ1005A102ETD25 for identical electrical characteristics but potential packaging differences. Verify physical footprint compatibility before substitution. Ensure impedance and current ratings match exactly to maintain circuit performance.
