MPZ1005S181HT000

Overview

The MPZ1005S181HT000 is a ferrite chip bead from the TDK MPZ-H series, designed for surface mount technology in a 0402 (1005 metric) package. It provides an impedance of 180 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current rating of 1.6 A and features a low maximum DC resistance of 85 mOhms. 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.

Feature Summary

• Designed for power line filtering applications
• Low DC resistance characteristic
• Single-line filter configuration

Applications

• Commercial grade electronic equipment
• Power line noise suppression
• EMC countermeasures in compact circuits

Procurement Notes

Verify the specific suffix HT000 against official TDK documentation to confirm packaging details such as reel or cut tape specifications. Ensure the order quantity aligns with manufacturer minimums if applicable. Cross-reference the RoHS status and lead times directly with authorized distributors or the manufacturer's latest production announcements to avoid discrepancies.

Selection Notes

Select this component when space constraints require a 0402 footprint for high-current noise suppression. The 1.6 A current rating makes it suitable for power lines where significant current flows alongside noise reduction requirements. Verify that the 180 Ohm impedance at 100 MHz matches the target noise frequency spectrum of the application circuit.

Part Context

This part belongs to the MPZ-H series of ferrite beads, which are engineered for high-current applications. The MPZ1005S181HT000 specifically addresses the need for compact EMC solutions in commercial-grade devices. It serves as a passive component to attenuate high-frequency electromagnetic interference on power rails without introducing excessive voltage drop due to its low DC resistance.

Replacement Considerations

Check for direct substitutes within the MPZ1005S series with identical impedance and current ratings. Verify pin compatibility and thermal characteristics before substituting with other manufacturers' 0402 ferrite beads.
