MPZ1608S102ATD25

Overview

The MPZ1608S102ATD25 is a shielded ferrite chip bead from the TDK MPZ series, designed for power line noise reduction in a 0603 (1.6mm x 0.8mm) SMD package. It offers an impedance of 1 kOhms at 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 800 mA and has a maximum DC resistance of 300 mOhms. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification for automotive reliability.

Feature Summary

• Provides noise reduction solutions specifically engineered for power lines.
• Features low direct current resistance to maintain compatibility with large currents.
• Includes shielding to prevent magnetic field interference.

Applications

• Automotive electronic circuits requiring AEC-Q200 compliance
• Power supply input filtering
• DC-DC converter output stages

Procurement Notes

Verify the specific suffix 'TD25' against the manufacturer's official datasheet to confirm packaging details and reel specifications. Ensure the application environment does not exceed the 800 mA continuous current rating or the +125°C maximum operating temperature. Confirm that the 1 kOhm impedance at 100 MHz aligns with the target noise frequency spectrum for the intended power line circuit.

Selection Notes

Select this component when high current handling is required alongside effective high-frequency noise suppression. The MPZ series is preferred over MMZ variants for power lines due to its lower DC resistance, which minimizes voltage drop and power loss under load. The 0603 footprint allows for compact board design while maintaining robust thermal performance for automotive applications.

Part Context

This part belongs to the TDK MPZ series of ferrite beads, which are distinct from the MMZ series by their optimization for power lines rather than signal lines. The MPZ series utilizes a shielded structure to contain magnetic flux, making it suitable for environments where electromagnetic interference must be strictly controlled. It complements other passive components in EMI suppression networks.

Replacement Considerations

The MMZ1608S102ATD25 is a related component but is rated for only 400 mA and higher DC resistance, making it unsuitable as a direct substitute for high-current power line applications. Verify if alternative MPZ series parts with different impedance values are needed based on specific noise frequency requirements.
