MPZ1005S121HT000

Overview

The TDK MPZ1005S121HT000 is a ferrite chip bead in the MMZ-H series, designed for general signal line noise suppression. It features a 0402 (1005 metric) SMD package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 700 mA and has a maximum DC resistance of 130 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective electromagnetic interference suppression for general signal lines
• Compact surface-mount design suitable for high-density PCB layouts
• Low DC resistance minimizes power loss in signal paths

Applications

• Noise suppression in cell phone circuits
• Signal line filtering in personal computers
• Interference reduction in TV tuners
• Power line noise removal in game machines

Procurement Notes

Verify the specific suffix HT000 against the official TDK datasheet to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit. 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 space constraints require a 0402 footprint for signal integrity management. The 120 Ohm impedance at 100 MHz targets common high-frequency noise profiles. Verify that the 700 mA current rating exceeds the maximum operating current of the protected line to prevent saturation. Consider the low DC resistance for applications where signal attenuation must be minimized.

Part Context

This ferrite bead belongs to the MPZ series, which utilizes TDK's proprietary technology for compact noise suppression. The MMZ-H series designation indicates a specific material composition optimized for high-frequency performance. These components are widely used in consumer electronics to meet regulatory emissions standards while maintaining signal fidelity in dense electronic assemblies.
