MMZ1005D680CT000

Overview

The TDK MMZ1005D680CT000 is a single-line ferrite chip bead in a 0402 (1005 metric) surface-mount package. It provides an impedance of 68 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 400 mA and has a maximum DC resistance of 380 mOhms. It operates within a temperature range of -55°C to +125°C. Physical dimensions are 1.0 mm length, 0.5 mm width, and 0.5 mm height.

Feature Summary

• Designed for high-speed signal line filtering to prevent radiated noise
• Maintains stable impedance characteristics at high frequencies
• Compact 0402 footprint suitable for space-constrained PCB layouts

Applications

• High-speed digital signal line noise suppression
• EMI filtering in portable electronic devices
• Power supply line decoupling in compact circuits

Procurement Notes

Verify the complete part number including the suffix CT000 to ensure correct packaging configuration. Confirm RoHS compliance status through official TDK documentation or authorized distributor declarations prior to procurement. Ensure the ordering quantity matches the required reel or cut tape specifications for production integration.

Selection Notes

Select this component when a 68 Ohm impedance at 100 MHz is required for EMI suppression in high-speed circuits. The 400 mA current rating must accommodate the maximum operating current of the target signal line. The 0402 package size is appropriate for dense surface-mount assemblies where minimal board area is available.

Part Context

This component belongs to the TDK MMZ series of ferrite beads, which are engineered for noise suppression in electronic circuits. The MMZ series utilizes specialized ferrite materials to provide effective attenuation of high-frequency electromagnetic interference while maintaining low DC resistance and handling specified current loads in compact form factors.

Replacement Considerations

Substitute parts must match the 0402 package, 68 Ohm impedance at 100 MHz, and 400 mA current rating. Verify that alternative ferrite beads from other manufacturers offer equivalent thermal performance and impedance curves to ensure circuit compatibility without redesign.
