MPZ1608S471ATD25

Overview

The MPZ1608S471ATD25 is a surface-mount ferrite chip bead from the TDK MPZ series, designed for power line applications. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 470 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 1000 mA. It has a maximum DC resistance of 300 mOhms and a tolerance of 25%. Certified to AEC-Q200 standards, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• AEC-Q200 qualified for automotive reliability requirements
• Designed specifically for power line noise suppression
• Shielded construction to minimize electromagnetic interference

Applications

• Automotive electronic circuits
• Power supply filtering
• DC-DC converter output stages

Procurement Notes

Verify the specific suffix TD25 against the official TDK datasheet to confirm packaging details and manufacturing origin. Ensure the selected variant matches the required power line application rather than signal line usage. Cross-reference the AEC-Q200 certification status with the latest product change notices to guarantee compliance with current automotive quality standards.

Selection Notes

Select this component when high current handling capability is required alongside significant impedance at 100 MHz. The 0603 footprint allows for compact board layouts in space-constrained designs. Compare the 1000 mA rating against peak load currents to prevent saturation. Consider the 300 mOhm DCR impact on voltage drop in low-voltage power rails.

Part Context

This part belongs to the MPZ series of ferrite beads, which are optimized for power lines. Unlike the MMZ series intended for signal lines, the MPZ series handles higher currents. The 1608 metric case size is standard for general-purpose SMD components, facilitating automated placement in high-volume manufacturing environments.

Replacement Considerations

Check for direct substitutes within the MPZ series with identical impedance and current ratings. Verify that any alternative maintains the same AEC-Q200 qualification and thermal characteristics.
