MPZ2012S331AT000

Overview

The MPZ2012S331AT000 is a surface-mount power line ferrite bead from the TDK MPZ series, designed for automotive and general power circuit applications. It features an 0805 (2012 Metric) package with dimensions of 2.0 mm x 1.25 mm. The component provides an impedance of 330 Ohms at 100 MHz and supports a maximum rated current of 2.5 A. Its DC resistance is specified at a maximum of 50 mOhms. The device operates within a temperature range of -40°C to +125°C and holds a Moisture Sensitivity Level of 1.

Feature Summary

• Provides noise suppression by simple series insertion in power lines without requiring parallel capacitors.
• Engineered specifically for high-current automotive and power circuit environments.
• Offers compact surface-mount footprint suitable for space-constrained designs.

Applications

• Automotive electronic systems
• Power supply input filtering
• DC-DC converter output stages

Procurement Notes

Verify the specific suffix 'A' against the manufacturer's latest datasheet to confirm tape-and-reel packaging orientation and marking codes. Ensure the procurement channel sources directly from authorized distributors or TDK-certified partners to guarantee authenticity. Cross-reference the RoHS compliance status with current environmental regulations before finalizing orders.

Selection Notes

Select this component when a 330 Ohm impedance at 100 MHz is required for power line noise attenuation. The 2.5 A current rating makes it suitable for moderate-power applications where low DC resistance is critical to minimize voltage drop. The 0805 package size offers a balance between thermal performance and board space efficiency compared to smaller footprints.

Part Context

This part belongs to the TDK MPZ Series, which specializes in chip beads for power lines. Unlike standard signal line beads, the MPZ series is optimized for higher current handling and lower DC resistance. It serves as a primary EMI suppression solution in automotive electronics and industrial power supplies where robust noise filtering is essential.

Replacement Considerations

The HF50ACC575032-T is listed as a manufacturer-recommended substitute. Note that the replacement uses a larger 2220 package and differs in impedance and current ratings. Verify electrical compatibility and mechanical fit before substitution.

FAQ
