MMZ1005B800CT000

Overview

The MMZ1005B800CT000 is a ferrite chip bead from the TDK MMZ series, designed for general signal line applications. It features an impedance of 80 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 450 mA. The component has a maximum DC resistance of 190 mOhms with a 25% tolerance. It utilizes a 0402 (1005 metric) surface-mount package measuring 1.0 mm in length, 0.5 mm in width, and 0.5 mm in height. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides electromagnetic interference suppression for single signal lines through high-impedance characteristics at target frequencies.
• Utilizes a compact 0402 surface-mount footprint to facilitate dense circuit board layouts.
• Engineered for stable performance across a wide industrial temperature range.

Applications

• General signal line filtering in electronic circuits
• Noise suppression on data transmission lines
• EMI mitigation in consumer electronics

Procurement Notes

Verify the specific suffix CT000 against official TDK documentation to confirm standard commercial grade specifications. Ensure the ordering code matches the required reel or cut tape packaging format. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status before procurement.

Selection Notes

Select this component when a low-profile ferrite bead is required for signal integrity management in space-constrained designs. The 450 mA current rating suits moderate signal currents without significant saturation. Compare the 80 Ohm impedance profile against circuit noise spectra to ensure effective attenuation at the targeted 100 MHz frequency band.

Part Context

This component belongs to the TDK MMZ series of ferrite beads, which are widely used for EMI suppression. The MMZ1005 designation indicates the 0402 case size. This specific variant targets general-purpose signal lines, distinguishing it from automotive-grade counterparts like the MMZ Auto series which require AEC-Q200 qualification.

Replacement Considerations
