Applications
- Automotive electronic circuits
- General signal line noise suppression
- Consumer data processing equipment
Procurement Notes
Verify the specific suffix TD25 against official TDK documentation to confirm packaging and tape specifications. Confirm current lifecycle status as distributors may list obsolete or active stock inconsistently. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit design.
Selection Notes
Select this component when a 1 kOhm impedance at 100 MHz is required for signal integrity in space-constrained designs. The 0805 footprint offers a balance between performance and board area. Verify that the 350 mA current rating exceeds the maximum operating current of the protected signal line to prevent saturation.
Part Context
This part belongs to the TDK MMZ series, which includes ferrite beads in sizes ranging from 1005 to 2012 metric. The series is engineered for broad compatibility across various electronic applications requiring effective high-frequency noise attenuation. The MMZ2012 variant specifically targets applications needing robust performance in a standard small outline package.
Replacement Considerations
Publicly confirmed substitutes include MMZ2012S121ATD25 and MMZ2012Y150BTD25. Verify impedance values and current ratings match the original design requirements before substitution.
