MMZ1608Q471BTA00

Overview

The TDK MMZ1608Q471BTA00 is a surface-mount ferrite bead from the MMZ series, designed for signal line noise suppression. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 470 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 700 mOhms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Provides high-impedance attenuation for high-frequency electromagnetic interference on signal lines
• Utilizes a compact 0603 surface-mount footprint for efficient PCB space utilization
• Maintains stable electrical characteristics across a wide industrial temperature range

Applications

• High-speed digital signal line filtering
• Clock circuit noise suppression
• Data bus EMI reduction

Procurement Notes

Verify the complete part number including the suffix BTA00 to ensure correct packaging and tape specifications. Confirm RoHS compliance status through official TDK documentation prior to integration. Cross-reference the impedance value at 100 MHz against schematic requirements to validate noise suppression performance for the specific application frequency.

Selection Notes

Select this component when signal integrity requires significant attenuation above 100 MHz while maintaining low insertion loss at DC. Ensure the circuit current does not exceed 300 mA to prevent saturation or thermal issues. The 0603 package is suitable for standard SMT assembly processes. Verify that the 700 mOhm DC resistance aligns with voltage drop constraints in the target power path.

Part Context

This component belongs to the TDK MMZ series of chip ferrite beads, which are widely used for EMI suppression in electronic circuits. The MMZ series offers various impedance values and current ratings within standardized packages. The Q471 designation indicates the specific 470 Ohm impedance characteristic at 100 MHz, distinguishing it from other variants in the same physical form factor.
