Overview
The TDK MMZ1608Y121BTD25 is a surface-mount ferrite bead in the MMZ Auto series, designed for signal line noise suppression. It features an impedance of 120 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 200 mOhms with a 25% tolerance. It operates within a temperature range of -55°C to +125°C. The package dimensions are 1.6 mm length, 0.8 mm width, and 0.8 mm height (0603 metric). It holds AEC-Q200 qualification.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- Designed for high-speed signal line noise suppression
- Compact 0603 surface-mount footprint
Applications
- Automotive electronic circuits
- High-speed signal line filtering
- EMI suppression in compact modules
Procurement Notes
Verify the specific suffix TD25 confirms the required packaging format and reel specifications against project requirements. Confirm AEC-Q200 certification status is explicitly documented in the official datasheet for automotive compliance. Ensure the 120 Ohm impedance value matches the target noise suppression frequency band. Validate that the 500 mA current rating meets the circuit's operational demands without saturation.
Selection Notes
Select this component when automotive-grade reliability is mandatory for signal integrity applications. The 0603 size suits space-constrained PCB layouts requiring effective EMI reduction. Compare the 200 mOhms DC resistance against power loss constraints in the signal path. Ensure the operating temperature range covers the environmental conditions of the final assembly location.
Part Context
This part belongs to the TDK MMZ Auto series, which specializes in ferrite beads for automotive electronics. The series provides solutions for suppressing electromagnetic interference in vehicle systems. The MMZ1608 designation indicates the standard 0603 case size used across many consumer and industrial devices as well.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative suppliers by matching impedance, current rating, and package dimensions.
