MPZ1005S300CT000

Overview

The TDK MPZ1005S300CT000 is a surface-mount ferrite bead designed for power line noise suppression. It features an impedance of 30 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 1.7 A. The component has a maximum DC resistance of 35 mOhms with a 25% impedance tolerance. 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 electromagnetic interference attenuation on power lines
• Supports high direct current loads up to 1.7 Amperes
• Utilizes compact 0402 surface-mount footprint for space-constrained designs

Applications

• Power supply input filtering
• DC-DC converter output noise suppression
• High-speed digital circuit power rail conditioning

Procurement Notes

Verify the specific suffix 'CT000' against official TDK documentation to confirm reel packaging specifications and tape-and-reel dimensions. Ensure the requested quantity aligns with standard manufacturing reel sizes. Confirm RoHS compliance status and material declarations directly from the manufacturer's datasheet or environmental reports prior to final procurement authorization.

Selection Notes

Select this component when low DC resistance is critical for minimizing voltage drop in high-current applications. The 30 Ohm impedance value targets specific noise frequencies around 100 MHz. Verify that the 1.7 A current rating exceeds the peak operational current of the target circuit to prevent saturation. Ensure the 0402 package size fits the available PCB real estate constraints.

Part Context

This part belongs to the TDK MPZ series of ferrite chip beads. The series is engineered for general-purpose noise suppression in electronic circuits. The MPZ designation typically indicates components optimized for power line applications compared to signal line variants. The 1005 metric code defines the standardized industry package size.
