MPZ1005A331ET000

Overview

The MPZ1005A331ET000 is a surface-mount ferrite bead from the TDK MPZ series, designed for wide-band power line applications. It features an impedance of 330 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 600 mA and has a maximum DC resistance of 300 mOhms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1.00 mm in length, 0.50 mm in width, and 0.50 mm in height, conforming to the 0402 (1005 metric) package.

Feature Summary

• Engineered for wide-band noise suppression on power lines
• High impedance characteristics across broad frequency ranges
• Automotive-grade reliability compliant with AEC-Q200 standards

Applications

• Noise filtering in automotive electronic systems
• Power supply line decoupling in embedded devices
• EMI suppression in compact consumer electronics

Procurement Notes

Verify the specific suffix 'ET000' against official TDK documentation to confirm packaging configuration and tape-and-reel specifications. Ensure that the selected variant meets the required AEC-Q200 qualification if used in automotive contexts. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when high impedance at 100 MHz is required for power line filtering in space-constrained designs. The 0402 footprint allows for dense PCB layouts. Consider the 600 mA current rating to ensure the component does not saturate under operational load conditions. Verify thermal performance within the specified -55°C to +125°C range for the intended environment.

Part Context

This ferrite bead belongs to the MPZ series, which is optimized for power line applications requiring wide-band noise suppression. The MPZ series distinguishes itself from signal line beads by offering higher current handling capabilities while maintaining effective EMI reduction. It serves as a critical passive component for maintaining signal integrity in noisy electrical environments.

Replacement Considerations

Consult TDK's official substitution guide for equivalent parts within the MPZ or MMZ series. Direct replacements must match the 330 Ohm impedance, 600 mA current rating, and 0402 package dimensions. Verify that any substitute maintains AEC-Q200 compliance if the application requires automotive-grade certification.
