MMZ1005S182ET000

Overview

The MMZ1005S182ET000 is a ferrite chip bead from the MMZ-E series, designed for signal line noise suppression. It features an impedance of 1.8 kOhms at 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 200 mA and has a maximum DC resistance of 1.5 Ohms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1 mm in length, 0.5 mm in width, and 0.5 mm in height, housed in a 0402 (1005 metric) SMD package.

Feature Summary

• Designed for general signal line noise reduction solutions
• Elevated self-resonant frequency extending into the GHz band
• Capable of addressing noise across a broad frequency range using a single element

Applications

• Signal line noise suppression
• High-frequency circuit filtering

Procurement Notes

Verify the specific suffix ET000 against official TDK documentation to confirm packaging details and compliance status. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the datasheet revision date to guarantee access to the most recent electrical characteristics and mechanical drawings before finalizing procurement orders.

Selection Notes

Select this component when high-impedance attenuation is required for signals up to 100 MHz while maintaining low DC resistance. The MMZ-E series offers superior performance compared to standard MMZ beads by pushing the self-resonant frequency higher. This allows for effective broadband noise absorption without requiring multiple components, simplifying layout and reducing board space consumption in dense designs.

Part Context

This part belongs to the MMZ-E series of ferrite beads manufactured by TDK Corporation. The series is characterized by enhanced high-frequency performance compared to previous generations. The MMZ1005 form factor provides a compact footprint suitable for modern surface-mount assembly processes, ensuring compatibility with automated pick-and-place equipment used in consumer electronics and industrial control systems.

Replacement Considerations

Direct substitutes include other MMZ1005 variants with matching 1.8 kOhm impedance and 200 mA ratings, such as MMZ1005A182ET or MMZ1005S182ET. Verify that alternative parts maintain similar self-resonant frequency characteristics to ensure equivalent high-frequency noise suppression capabilities.
