MMZ0402Y750CT000

Overview

The MMZ0402Y750CT000 is a surface-mount ferrite bead from the TDK MMZ series, designed for signal line noise suppression. It features a 01005 (0402 metric) package with dimensions of 1.0 mm length, 0.5 mm width, and 0.3 mm height. The component provides an impedance of 75 Ohms at a test frequency of 100 MHz, with a tolerance of ±25%. It supports a maximum DC current of 250 mA and has a maximum DC resistance of 700 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective high-frequency noise attenuation for sensitive signal lines
• Compact 01005 footprint enables dense circuit board layouts
• Capable of handling moderate DC bias currents without saturation

Applications

• Noise filtering in portable electronic devices
• Signal integrity protection in consumer electronics
• EMI suppression on data transmission lines

Procurement Notes

Verify that the specific order matches the MMZ0402Y750CT000 designation to ensure correct impedance and current ratings. Confirm package compatibility with automated pick-and-place equipment due to the small 01005 form factor. Check manufacturing date codes and lot traceability if required by quality standards. Ensure storage conditions maintain moisture sensitivity level integrity prior to soldering.

Selection Notes

Select this component when space constraints require a 01005 package size while maintaining signal line filtering requirements. The 75 Ohm impedance at 100 MHz suits general-purpose noise suppression rather than power rail filtering. Verify that the 250 mA current rating exceeds the maximum operating current of the target circuit to prevent excessive heating or performance degradation during normal operation.

Part Context

This part belongs to the TDK MMZ series of multilayer ferrite beads, widely used for EMI suppression in compact electronic designs. The MMZ family offers various impedance values and package sizes to accommodate different circuit densities and noise profiles. As a passive component, it complements active circuits by attenuating unwanted high-frequency interference without introducing significant signal distortion.

Replacement Considerations

Direct substitutes must match the 01005 package, 75 Ohm impedance at 100 MHz, and 250 mA current rating. Verify thermal characteristics and DC resistance limits to ensure equivalent performance. Cross-reference with other manufacturers' ferrite beads offering identical dimensional and electrical specifications.
