MMZ2012Y301BT000

Overview

The MMZ2012Y301BT000 is a surface-mount ferrite bead from the TDK MMZ series, designed for signal line noise suppression. It features a 0805 (2012 metric) package with dimensions of 2.00mm length and 1.25mm width. The component provides an impedance of 300 ohms at 100 MHz. It supports a maximum current rating of 400mA and has a maximum DC resistance of 500 milliohms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high impedance for effective signal line noise attenuation
• Compact surface-mount design suitable for space-constrained applications
• Capable of handling specified continuous current without saturation

Applications

• Noise suppression in mobile phone circuits
• Signal integrity management in personal computers
• Electromagnetic interference filtering in television systems

Procurement Notes

Verify component authenticity through authorized distributors. Confirm that the specific suffix matches the required impedance and current ratings. Check for recent discontinuation notices regarding the MMZ2012 series before finalizing procurement plans.

Selection Notes

Select this component when 300 ohms impedance at 100 MHz is required for signal lines. Ensure the 400mA current rating meets circuit requirements. Verify compatibility with standard 0805 footprint layouts during PCB design.

Part Context

This ferrite bead belongs to the MMZ series, which is engineered for suppressing electromagnetic interference in electronic devices. The MMZ2012Y301BT000 specifically targets signal lines requiring moderate noise reduction while maintaining signal integrity in compact form factors.

Replacement Considerations

TDK has announced the discontinuation of the MMZ2012 series. Engineers should evaluate alternative ferrite beads from current production lines or other manufacturers offering equivalent 0805 package dimensions and 300-ohm impedance characteristics.
