MMZ1608D800C

Overview

The MMZ1608D800C is a ferrite chip bead from the TDK MMZ series, designed for signal line applications. It features an impedance of 80 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 500 mA. The component has a maximum DC resistance of 300 mOhms with a 25% impedance tolerance. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1.6 mm in length, 0.8 mm in width, and 0.6 mm in height, conforming to the 0603 (1608 metric) package size.

Feature Summary

• Provides electromagnetic interference suppression for single signal lines
• Constructed for surface mount technology integration
• Engineered for high-temperature operational stability

Applications

• Signal line noise filtering
• Electromagnetic interference suppression circuits

Procurement Notes

Verify the specific suffix against official documentation, as variations such as 'CTAH0' or 'CTDH5' may indicate differences in packaging or automotive qualification status like AEC-Q200. Confirm the exact thickness parameter, as datasheets for similar MMZ1608 variants list heights of either 0.6 mm or 0.8 mm. Ensure the selected part matches the required impedance tolerance and current rating for the target circuit design before procurement.

Selection Notes

Select this component when a compact 0603 footprint is required for signal integrity management. The 80 Ohm impedance value is suitable for attenuating high-frequency noise above 100 MHz. Consider the 500 mA current rating to ensure the component does not saturate under normal operating conditions. Verify that the 300 mOhm DC resistance meets the voltage drop requirements of the specific signal path.

Part Context

This component belongs to the TDK MMZ series of ferrite beads, which are widely used for EMI suppression in electronic devices. The MMZ1608 designation indicates a standard 1608 metric case size. These components are essential for maintaining signal quality in digital and analog circuits by dissipating high-frequency noise energy as heat.

Replacement Considerations

Equivalent parts include the MMZ1608D800BTA00 and MMZ1608D800CTAH0. Verify dimensional compatibility, specifically checking if the replacement requires a 0.6 mm or 0.8 mm height profile.
