MMZ1005Y-800C

Overview

The TDK MMZ1005Y-800C is a ferrite chip bead in the MMZ series, designed for signal line noise suppression. It features an impedance of 80 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 450 mA. The component has a maximum DC resistance of 170 mOhms with a tolerance of 25%. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1.0 mm in length, 0.5 mm in width, and 0.5 mm in height, conforming to the 0402 (1005 metric) package.

Feature Summary

• Provides effective high-frequency noise attenuation for sensitive signal lines through ferrite material properties.
• Supports surface-mount assembly using standard SMD/SMT termination types for automated manufacturing.
• Maintains stable electrical performance across a wide industrial operating temperature range.

Applications

• Noise suppression on general-purpose signal lines
• High-frequency interference filtering in compact electronic circuits

Procurement Notes

Verify that the specific part number matches the required impedance and current ratings for your circuit design. Confirm the package size compatibility with your PCB footprint. Ensure the supplier provides original manufacturer documentation to guarantee component authenticity and traceability before finalizing orders.

Selection Notes

Select this component when signal line integrity requires noise reduction without significant DC voltage drop. The 450 mA current rating suits low-power signal applications. The 0402 package allows for dense board layouts. Verify that the 80 Ohm impedance at 100 MHz aligns with the target noise frequencies in your specific application environment.

Part Context

This component belongs to the TDK MMZ series of ferrite beads, which are widely used for electromagnetic interference suppression. The MMZ1005 designation indicates the 0402 case size, while the suffix specifies the electrical characteristics. This series is known for providing reliable noise filtering in consumer and industrial electronics where space is limited.

Replacement Considerations
