MPZ1608S221ATD25

Overview

The MPZ1608S221ATD25 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 220 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 2.2 A and has a maximum DC resistance of 50 mOhms. The tolerance is specified at 25%. Operating temperatures range from -55°C to +125°C.

Feature Summary

• Shielded construction minimizes electromagnetic interference coupling between adjacent circuits.
• Optimized for power line noise suppression in high-current environments.
• Automotive-grade reliability compliant with AEC-Q200 standards.

Applications

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

Procurement Notes

Verify the specific suffix TD25 against the official TDK datasheet to confirm packaging and tape-and-reel specifications. Ensure the design accounts for the 2.2 A current rating to prevent saturation or excessive temperature rise. Confirm RoHS compliance status through the manufacturer's latest documentation before finalizing procurement.

Selection Notes

Select this component when shielding is required to prevent magnetic field leakage in dense layouts. The 2.2 A current handling capability distinguishes it from signal-line variants like the MMZ series. Verify that the 220 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum of the power rail being filtered.

Part Context

This part belongs to the MPZ series of shielded ferrite beads manufactured by TDK Corporation. Unlike unshielded counterparts, the MPZ series incorporates a metal shield layer to contain magnetic flux. This series is specifically engineered for power lines where both high current capacity and EMI suppression are critical requirements.

Replacement Considerations

MPZ1608S221A is listed as a related part number alias. Verify if the non-suffixed version meets identical shielding and current specifications. Cross-reference with MPZ1608S221ATA00 for potential equivalent performance in power line applications.
