Overview
The TDK MMZ0603D121ET000 is a single-line ferrite bead in the MMZ-E series, housed in a 0201 (0603 metric) surface-mount package measuring 0.60mm x 0.30mm x 0.33mm. It provides an impedance of 120 Ohms at 100 MHz with a maximum DC resistance of 2.4 Ohms and a rated current of 125mA. The component operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.
Feature Summary
- Designed for high-speed signal line filtering applications
- Compact 0201 footprint suitable for space-constrained layouts
- Capable of handling continuous DC currents up to 125mA
Applications
- High-speed digital signal line noise suppression
- Power supply filtering in compact electronic modules
- EMI reduction in portable consumer devices
Procurement Notes
Verify the specific suffix ET000 against official TDK documentation to confirm packaging type and tape specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design before finalizing procurement orders.
Selection Notes
Select this component when a small form factor is required for signal integrity management. The 120 Ohm impedance at 100 MHz targets common high-frequency noise profiles. Verify that the 125mA current rating exceeds the maximum operating current of the protected line to prevent saturation.
Part Context
This part belongs to the TDK MMZ-E series of chip ferrite beads. The series offers various impedance values and current ratings within standard metric footprints, providing engineers with options for balancing size, performance, and power handling in modern electronic designs.
Replacement Considerations
Cross-reference with other MMZ0603 variants from TDK or equivalent ferrite beads from other manufacturers. Ensure substitute parts match the 0201 dimensions, 120 Ohm impedance at 100 MHz, and 125mA current rating to maintain circuit compatibility.
