Overview
The MMZ1608R471ATA00 is a single-line ferrite bead from the TDK MMZ series, designed for surface-mount applications in the 0603 (1608 metric) package. It exhibits an impedance of 470 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 500 mA and maintains a maximum DC resistance of 300 mOhms. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides high-impedance noise suppression for signal lines in compact surface-mount configurations
- Engineered for stable performance across wide industrial temperature variations
- Constructed with low DC resistance to minimize power loss in current-carrying paths
Applications
- High-frequency noise filtering in portable electronic devices
- Signal line protection in consumer electronics circuits
- EMI suppression in automotive infotainment systems
Procurement Notes
Verify the complete part number including suffixes against official TDK documentation to ensure correct impedance and current ratings. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Cross-reference datasheet specifications with PCB layout constraints to validate thermal and electrical performance.
Selection Notes
Select this component when a 470 Ohm impedance at 100 MHz is required for signal integrity management. Ensure the circuit current does not exceed 500 mA to prevent saturation. The 0603 footprint allows for dense board layouts while maintaining adequate thermal dissipation characteristics for standard operating conditions.
Part Context
This ferrite bead belongs to the MMZ series, which offers various impedance values and current ratings in standardized metric packages. The MMZ1608R471ATA00 specifically addresses mid-range noise suppression needs where moderate current handling is essential. It complements other passive components in EMI filter networks.
Replacement Considerations
Publicly confirmed substitutes include Murata BLM15PX601SN1D and MPZ1608B471ATA00. Verify impedance curves and current ratings before substitution as physical dimensions may vary slightly between manufacturers.
