MMZ1608F470BTA00

Overview

The TDK MMZ1608F470BTA00 is a surface-mount ferrite bead designed for signal line filtering in compact electronic assemblies. It features an impedance of 47 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 500 mA and has a maximum DC resistance of 400 mOhms. It operates within a temperature range of -55°C to +125°C. The device utilizes a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height.

Feature Summary

• Provides electromagnetic interference suppression for single-signal lines through high-frequency impedance characteristics.
• Supports surface-mount assembly using standard SMD/SMT termination types.
• Maintains operational stability across extended industrial temperature ranges.

Applications

• Signal line filtering in portable electronic devices
• Electromagnetic compatibility enhancement in battery chargers
• Noise suppression in power supply circuits

Procurement Notes

Verify the specific ordering suffix BTA00 to ensure correct packaging configuration, as variations may exist. Confirm RoHS compliance status through official documentation before integration. Cross-reference the manufacturer part number MMZ1608F470BTA00 with distributor catalogs to validate authenticity and current production status. Ensure design files match the specified 0603 footprint dimensions.

Selection Notes

Select this component when a 47 Ohm impedance at 100 MHz is required for noise attenuation on single-ended signals. The 500 mA current rating suits low-power signal paths rather than high-current power rails. The 0603 package size allows for dense PCB layouts where space is constrained. Verify that the 400 mOhm DC resistance does not introduce excessive voltage drop in the target circuit application.

Part Context

This component belongs to the TDK MMZ series of ferrite beads, which are widely used for EMI suppression in consumer electronics and industrial equipment. The MMZ series offers various impedance values and current ratings within standardized package sizes. The MMZ1608F470BTA00 specifically addresses the need for compact, high-performance filtering solutions in modern miniaturized devices requiring reliable signal integrity.

Replacement Considerations

Consult official substitution guides for equivalent ferrite beads with matching 47 Ohm impedance and 0603 footprint. Verify current handling capabilities and DC resistance specifications against the original requirements. Ensure thermal performance and mounting compatibility remain consistent with the existing design constraints.
