Overview
The MMZ1608B301CTDH5 is a ferrite chip bead from the TDK MMZ series, designed for surface mount technology in a 0603 (1608 metric) package. It provides an impedance of 300 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 500 mA and has a maximum DC resistance of 250 mOhms. 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 0.6 mm in height.
Feature Summary
- AEC-Q200 qualified for automotive reliability standards
- Designed specifically for signal line noise suppression
- Compact 0603 surface mount footprint
Applications
- Automotive grade electronic circuits
- Signal line EMI suppression
- High-frequency noise filtering in compact devices
Procurement Notes
Verify the specific suffix CTDH5 against official TDK documentation to confirm AEC-Q200 qualification and signal line designation. Ensure the ordering part number matches the required impedance and current ratings for the target application. Cross-reference datasheets for any recent product change notices or obsolescence alerts before finalizing procurement.
Selection Notes
Select this component when a 300 Ohm impedance at 100 MHz is required for signal integrity in automotive or industrial environments. The 500 mA current rating suits moderate power signal lines. Compare with MMZ1608D301BTD25 if lower current handling is acceptable but higher robustness is needed, or choose MMZ1608B301CTAH0 if automotive qualification is not required.
Part Context
This part belongs to the TDK MMZ series of ferrite beads, which are widely used for electromagnetic interference suppression. The MMZ series offers various impedance values and current ratings in standard SMD packages. The B-series typically denotes general-purpose or specific characteristic variants within the broader MMZ family, while the D-series often indicates automotive-grade versions.
Replacement Considerations
MMZ1608D301BTD25 is a verified automotive-grade alternative with similar 300 Ohm impedance but rated for 300 mA max DC current and 700 mOhm DCR. MMZ1608B301CTAH0 is a non-automotive equivalent with identical electrical parameters but lacks AEC-Q200 certification.
