Overview
The MMZ0603S471HTD25 is a surface-mount ferrite bead from the TDK MMZ series, designed for general signal line noise suppression. It features a compact 0603 (1608 metric) package with dimensions of 0.6mm x 0.3mm x 0.3mm. 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 310 mA and has a maximum DC resistance of 0.65 ohms. The device operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification for automotive reliability.
Feature Summary
- AEC-Q200 qualified for automotive applications
- Low DC resistance design for signal lines
- Compact 0603 surface-mount footprint
Applications
- General signal line noise suppression in automotive electronics
- Power supply filtering in automotive modules
- High-frequency noise attenuation in compact electronic devices
Procurement Notes
Verify the specific suffix HTD25 against official TDK documentation to confirm the 310 mA current rating and 0.65 ohm DC resistance. Ensure the ordering part number matches the required impedance and package type. Confirm AEC-Q200 compliance if automotive grade certification is mandatory for the target application.
Selection Notes
Select this component when low DC resistance is critical for maintaining signal integrity while providing high impedance at 100 MHz. The 310 mA current handling capability suits moderate power applications. The AEC-Q200 qualification makes it suitable for automotive environments requiring extended temperature stability and reliability standards.
Part Context
This part belongs to the TDK MMZ series of chip beads, which utilizes proprietary ferrite technology for efficient noise removal across wide frequency ranges. The series includes various packages and ratings, with the 'S' variant typically indicating specific performance characteristics within the 0603 form factor.
Replacement Considerations
Check TDK datasheets for other MMZ0603S variants with matching 470 ohm impedance and compatible current ratings. Verify that any substitute maintains the same 0603 footprint and AEC-Q200 qualification if automotive use is required.
