MPZ1608S102ATA00

Overview

The MPZ1608S102ATA00 is a shielded ferrite chip bead from the TDK MPZ series, designed for power line applications. It features a 0603 (1608 metric) surface-mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.8 mm height. The component provides an impedance of 1 kOhms at a test frequency of 100 MHz, with a tolerance of ±25%. It supports a maximum DC current of 800 mA and has a maximum DC resistance of 300 mOhms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference radiation
• Designed specifically for power line noise suppression
• Supports high current handling capabilities

Applications

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

Procurement Notes

Verify the specific suffix 'ATA00' during procurement to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets prior to finalizing orders. Ensure the selected supplier provides valid traceability records for quality assurance purposes in critical electronic assemblies.

Selection Notes

Select this component when shielding is required to prevent radiated emissions from the ferrite bead itself. The 800 mA current rating makes it suitable for moderate power rails where significant noise attenuation at 100 MHz is necessary. Compare against unshielded alternatives if space constraints are less critical than cost, but prioritize this model for EMI-sensitive power distribution networks requiring compact 0603 footprints.

Part Context

This part belongs to the TDK MPZ series of shielded ferrite beads. Unlike the MMZ series which targets signal lines, the MPZ series is optimized for power lines, offering higher current capacity. The 0603 form factor allows for dense PCB layouts while maintaining effective noise suppression characteristics for modern electronic devices requiring robust EMI management.

Replacement Considerations

The MMZ1608S102A is listed as a previous part number revision by the manufacturer. However, it lacks the 'S' designation indicating shielding and has different electrical parameters (400 mA max current, 500 mOhm DCR). Direct substitution is not recommended without verifying that the unshielded nature and lower current rating meet the specific circuit requirements.
