MMZ0603Y121CT000

Overview

The TDK MMZ0603Y121CT000 is a single-line ferrite bead in a 0201 (0603 metric) surface-mount package. It exhibits an impedance of 120 Ohms at 100 MHz with a maximum DC resistance of 390 mOhms and a current rating of 200 mA. The component operates within a temperature range of -55°C to +125°C and measures 0.6 mm x 0.3 mm x 0.3 mm.

Feature Summary

• Designed for high-speed signal line filtering
• Prevents radiated noise emission
• Maintains impedance integrity at high frequencies

Applications

• High-speed digital signal lines
• Noise suppression in compact electronic circuits
• EMI reduction in portable devices

Procurement Notes

Verify the suffix 'Y' against datasheet specifications to confirm the 200mA current rating and 390mOhm DCR, as other suffixes like 'D' indicate different electrical characteristics. Ensure the ordering code matches the required impedance tolerance and packaging format. Cross-reference the manufacturer part number with authorized distributor listings to confirm active status and availability.

Selection Notes

Select this component when space constraints require a 0201 footprint for EMI suppression. Choose based on the 120 Ohm impedance requirement at 100 MHz and the 200 mA current handling capability. Verify that the low DC resistance of 390 mOhms meets voltage drop requirements for the specific signal line application.

Part Context

This component belongs to the TDK MMZ series of ferrite beads, which are engineered for noise suppression in small form factors. The MMZ series provides reliable performance for protecting sensitive electronics from electromagnetic interference while maintaining signal integrity in high-density printed circuit board layouts.
