Overview
The TDK MMZ1608R121ATA00 is a single-line surface-mount ferrite bead from the MMZ series, designed for signal line applications. It features an impedance of 120 Ohms at 100 MHz and a maximum DC resistance of 180 mOhm. The component supports a rated current of 500 mA and operates within a temperature range of -55°C to +125°C. Housed in a standard 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and a maximum height of 0.95 mm, it provides effective electromagnetic interference suppression.
Feature Summary
- Provides high impedance attenuation for noise suppression on signal lines
- Supports continuous operation under rated current conditions without saturation
- Complies with RoHS directives and halogen-free standards
Applications
- Signal line filtering in electronic circuits
- Electromagnetic interference suppression in portable devices
- Noise reduction in high-speed digital interfaces
Procurement Notes
Verify the specific suffix 'A' against official TDK documentation to confirm material composition and compliance status. Ensure the ordering quantity aligns with tape-and-reel packaging requirements. Cross-reference the part number with the latest datasheet revision to confirm availability and manufacturing status before finalizing procurement plans.
Selection Notes
Select this component when a 120 Ohm impedance at 100 MHz is required for signal integrity management. The 500 mA current rating suits low-power signal paths rather than power delivery lines. The 0603 footprint allows for compact board layouts where space is constrained compared to larger ferrite beads.
Part Context
This component belongs to the TDK MMZ series of chip ferrite beads, which are widely used for EMI suppression. The MMZ1608R121ATA00 specifically utilizes a monolithic ceramic structure optimized for high-frequency noise absorption. It serves as a passive filter element in modern electronics requiring reliable signal conditioning.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Verify compatibility with alternative manufacturers by matching impedance curves, current ratings, and physical dimensions.
