MMZ1005Y400CTD25

Overview

The MMZ1005Y400CTD25 is a ferrite chip bead from the TDK MMZ series, designed for signal line noise suppression. It features a 0402 (1005 metric) surface-mount package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 40 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 550 mA and has a maximum DC resistance of 100 mOhms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Provides effective high-frequency noise attenuation for sensitive signal lines through ferrite material properties.
• Compact 0402 footprint enables dense circuit board layouts in space-constrained electronic designs.
• Rated for automotive-grade reliability standards ensuring stability under varying thermal conditions.

Applications

• Noise suppression on high-speed digital signal lines
• EMI filtering in automotive electronic control units
• Signal integrity protection in consumer electronics

Procurement Notes

Verify the specific suffix CT against official TDK documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application environment. Cross-reference the AEC-Q200 qualification status if automotive compliance is mandatory for the design.

Selection Notes

Select this component when low impedance at DC is critical alongside moderate noise filtering at 100 MHz. The 550 mA rating suits low-power signal paths rather than power rails. Consider the 0402 size constraint and ensure PCB land pattern compatibility with standard SMT processes for reliable soldering.

Part Context

This part belongs to the MMZ series of ferrite beads, widely used for EMI suppression. The MMZ1005Y400CTD25 specifically targets applications requiring compact size and reliable performance in both commercial and automotive sectors. It complements other components in the MMZ family offering various impedance values.

Replacement Considerations

Check TDK's MMZ1005Y series for alternative impedance values or current ratings. Verify cross-compatibility with other manufacturers' 0402 ferrite beads only if electrical parameters match exactly.
