MPZ1005F470ET000

Overview

The MPZ1005F470ET000 is a ferrite chip bead manufactured by TDK Corporation, designed for power line noise suppression in the GHz frequency range. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.00mm length, 0.50mm width, and 0.55mm maximum height. The component provides an impedance of 47 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 450 mA and has a maximum DC resistance of 700 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Engineered specifically for wide-band power line noise countermeasures in the GHz frequency spectrum.
• Utilizes a compact 0402 surface-mount footprint suitable for high-density PCB layouts.
• Capable of handling higher DC currents compared to standard signal line ferrites.

Applications

• Power supply lines requiring GHz-range noise suppression
• High-density electronic circuits needing compact filtering solutions
• Signal integrity management on power distribution networks

Procurement Notes

Verify the specific suffix 'E' against the official TDK datasheet to confirm it denotes the correct series variant for power line applications. Ensure the selected packaging matches production requirements, as options typically include cut tape, reel, or Digi-Reel formats. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components and confirm RoHS compliance status.

Selection Notes

Select this component when GHz-wideband attenuation is required on power rails rather than single-frequency signal lines. The 450 mA current rating distinguishes it from lower-current signal line beads like the MMZ series. Confirm that the 47 Ohm impedance at 100 MHz aligns with the target noise frequency profile. Ensure the 0402 package fits the available board space constraints.

Part Context

This component belongs to the MPZ series, which is distinct from the MMZ series designed for signal lines. The MPZ series is characterized by its ability to handle higher DC currents and provide effective noise suppression across a broader, higher frequency range. It serves as a specialized passive filter for modern high-speed digital systems where power line noise can interfere with sensitive components.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative ferrite beads based on impedance curves, current ratings, and package dimensions before substitution.
