Overview
The MMZ1005F470CTD25 is a ferrite chip bead from the TDK MMZ Auto series, designed for signal line applications in automotive environments. It features a 0402 (1005 metric) surface-mount package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 47 Ohms at a test frequency of 100 MHz, with a tolerance of 25%. It supports a maximum DC current of 100 mA and has a maximum DC resistance of 600 mOhms. Operating temperatures range from -55°C to +125°C. The part is qualified under AEC-Q200 standards.
Feature Summary
- AEC-Q200 qualified for automotive reliability
- Designed for high-speed signal line suppression
- Compact 0402 surface-mount form factor
Applications
- Automotive electronic circuits
- High-speed signal line noise suppression
- Embedded systems requiring AEC-Q200 compliance
Procurement Notes
Verify the specific suffix TD25 against the manufacturer's latest documentation to confirm packaging configuration and tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design. Cross-reference the AEC-Q200 qualification status with project requirements before finalizing procurement orders.
Selection Notes
Select this component when designing for automotive signal integrity where compact size and low DC resistance are critical. The 100 mA current rating suits low-power signal lines rather than power distribution paths. Consider the 47 Ohm impedance profile at 100 MHz to ensure effective high-frequency noise attenuation without excessive signal degradation.
Part Context
This part belongs to the TDK MMZ Auto series, which specializes in ferrite beads for automotive electronics. The MMZ1005F470CTD25 specifically targets the 0402 footprint market, offering a balance between physical size and electrical performance for modern miniaturized automotive PCBs.
Replacement Considerations
Check for direct substitutes within the MMZ Auto series that share the same 0402 footprint and AEC-Q200 qualification. Verify impedance and current ratings match exactly to maintain circuit performance.
