Overview
The MMZ1005F121ETD25 is a ferrite bead from the TDK MMZ-E series, designed for surface-mount applications in the 0402 (1005 metric) package. It provides an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 200 mA and has a maximum DC resistance of 1.5 Ohms. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.
Feature Summary
- Automotive-grade reliability certified under AEC-Q200 standards
- Compact 0402 surface-mount footprint for space-constrained designs
- Signal line filtering capability with specified impedance characteristics
Applications
- Automotive electronic circuit protection
- High-frequency noise suppression in signal lines
- EMI reduction in compact consumer electronics
Procurement Notes
Verify the specific suffix 'TD25' against official TDK documentation to confirm tape and reel specifications. Ensure the selected variant matches the required automotive qualification level. Cross-reference the impedance value and current rating with the target circuit design requirements before finalizing procurement orders.
Selection Notes
Select this component when a small form factor is required for automotive or industrial applications. The 120 Ohm impedance at 100 MHz targets specific high-frequency noise profiles. Verify that the 200 mA current rating exceeds the maximum operating current of the protected line to prevent saturation.
Part Context
This part belongs to the MMZ-E series, which focuses on automotive-grade ferrite beads. The series offers various impedance values in standard metric packages. The MMZ1005F121ETD25 specifically addresses the need for reliable EMI suppression in vehicles where space is limited and environmental durability is critical.
Replacement Considerations
Consult the TDK MMZ-E series catalog for alternative impedance values or current ratings. Verify package compatibility and electrical parameters before substituting with other manufacturers' components.
