MMZ1005F470CT000

Overview

The TDK MMZ1005F470CT000 is a ferrite chip bead designed for signal line noise suppression. It features an impedance of 47 Ohms at a test frequency of 100 MHz. The component supports a maximum DC current of 100 mA with a tolerance of 25%. Its maximum DC resistance is specified at 600 mOhms, while the Mouser listing indicates a maximum of 800 mOhms. Operating temperatures range from -55°C to +125°C. The device utilizes a 0402 (1005 metric) surface mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height.

Feature Summary

• Designed specifically for high-frequency noise suppression in signal lines
• Utilizes a compact 0402 surface-mount footprint for space-constrained applications
• Provides stable electrical performance across a wide industrial temperature range

Applications

• High-speed digital signal line filtering
• Noise suppression in portable electronic devices
• EMI reduction in communication equipment circuits

Procurement Notes

Verify the specific suffix against official TDK documentation to confirm exact electrical tolerances and packaging configurations. Cross-reference manufacturer datasheets for precise DC resistance limits as distributor listings may vary. Ensure compatibility with automated assembly processes given the small 0402 package size. Confirm RoHS compliance status directly with the supplier prior to integration into final assemblies.

Selection Notes

Select this component when signal integrity requires attenuation of high-frequency interference without affecting low-frequency data transmission. The 100 mA current rating suits low-power logic interfaces. Evaluate thermal management requirements within the 125°C operational limit. Compare against alternative series if higher current handling or different impedance characteristics are necessary for the specific circuit topology.

Part Context

This part belongs to the TDK MMZ series of ferrite beads, which are widely used for electromagnetic interference suppression. The MMZ series offers various impedance values and current ratings in standard surface-mount packages. This specific model represents a common value for general-purpose signal line protection in consumer electronics and industrial control systems requiring reliable noise filtering.

Replacement Considerations

MMZ1005F470C is identified as a previous part number revision by the manufacturer.
