MMZ1005S102ET000

Overview

The TDK MMZ1005S102ET000 is a multilayer ferrite bead from the MMZ-E series, designed for signal line noise suppression. 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 Ohm. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer chip construction for effective high-frequency noise attenuation in compact designs
• Optimized for signal line applications to suppress electromagnetic interference
• Automotive-grade qualification ensuring reliability under varying thermal conditions

Applications

• Signal line noise suppression in automotive electronic systems
• High-speed data interface filtering in consumer electronics
• Power supply output filtering for sensitive digital circuits

Procurement Notes

Verify the specific suffix ET000 against the official TDK datasheet to confirm the exact impedance tolerance and packaging configuration. Ensure the selected variant matches the required DC current rating of 250 mA for the target circuit. Cross-reference the AEC-Q200 qualification status if the application demands automotive compliance standards.

Selection Notes

Select this component when space constraints require a 0402 footprint for noise filtering. The 1 kOhm impedance at 100 MHz makes it suitable for suppressing noise in moderate-speed digital signals. Consider the 250 mA current rating to prevent saturation or excessive heating in the power path. The wide operating temperature range supports deployment in harsh environments.
