Overview
The MMZ1608S800ATD25 is a ferrite chip bead from the MMZ Auto series, manufactured by TDK. It features an impedance of 80 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 500 mA. The component has a maximum DC resistance of 150 mOhms with a tolerance of 25%. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1.6 mm in length, 0.8 mm in width, and 0.8 mm in height, conforming to the 0603 (1608 metric) SMD/SMT package. It holds AEC-Q200 qualification for automotive reliability.
Feature Summary
- AEC-Q200 qualified for automotive grade reliability
- Designed for signal line noise suppression
- Compact 0603 surface mount footprint
Applications
- Automotive electronic systems
- Signal line filtering
- Noise suppression circuits
Procurement Notes
Verify the specific suffix TD25 against the official TDK datasheet to confirm packaging details such as reel size or tape specifications. Ensure the order matches the exact part number to avoid discrepancies in impedance or current ratings. Cross-reference the manufacturer's latest documentation for any potential obsolescence notices or parameter updates before finalizing procurement.
Selection Notes
Select this component when a low-impedance ferrite bead is required for high-current signal lines up to 500 mA. The 80 Ohm impedance provides effective noise attenuation at 100 MHz while maintaining low DC resistance. The wide operating temperature range and automotive qualification make it suitable for harsh environments where standard commercial parts may fail.
Part Context
This part belongs to the TDK MMZ Auto series, which is specifically engineered for automotive applications. The series offers various impedance values and current ratings in standardized packages. The MMZ1608S800ATD25 represents the 0603 form factor variant, balancing size constraints with performance requirements for modern automotive PCB layouts.
Replacement Considerations
Check for other MMZ1608 variants with identical 80 Ohm impedance and 500 mA rating. Verify that any substitute maintains AEC-Q200 certification and compatible thermal characteristics. Ensure the replacement part fits the same 0603 land pattern without requiring layout modifications.
