Overview
The MMZ1005F181ETD25 is a surface-mount ferrite bead from the TDK MMZ-E series, designed for EMI suppression in automotive applications. It features a 0402 (1005 metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 180 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 200 mA and has a maximum DC resistance of 1.6 Ohms. The device operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- Compact 0402 surface-mount footprint for space-constrained designs
- High-temperature operation up to +125°C
Applications
- Electronic Control Units (ECUs)
- Automotive modules
- Car multimedia and telematics systems
Procurement Notes
Verify the complete part number including suffixes to ensure correct impedance and current ratings. Confirm AEC-Q200 qualification status if automotive compliance is required. Check datasheet for specific impedance curves and thermal characteristics relevant to the application environment.
Selection Notes
Select this component when a compact ferrite bead with 180 Ohms impedance at 100 MHz is needed for 200 mA circuits. Ensure the 0402 package fits the PCB layout constraints. Verify that the 1.6 Ohms DC resistance meets voltage drop requirements for the specific signal line or power rail.
Part Context
This part belongs to the TDK MMZ-E Auto Series, which specializes in ferrite chip beads for automotive electronics. The series offers various impedance values and current ratings in standard packages like 0402, 0603, and 1206, all meeting AEC-Q200 standards for durability in vehicle environments.
Replacement Considerations
Check TDK MMZ1005F181ETxx variants for identical electrical specs. Compare impedance curves and DC resistance with other manufacturers' 0402 ferrite beads rated for 200 mA and 180 Ohms at 100 MHz to ensure functional equivalence.
