MPZ1005S121CT000

Overview

The MPZ1005S121CT000 is a ferrite chip bead from the MPZ series, manufactured by TDK Corporation. It features a 0402 (1005 metric) surface-mount package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 1.2 A and has a maximum DC resistance of 90 mOhms. The operating temperature range spans from -55°C to +125°C.

Feature Summary

• Provides high-frequency noise suppression through ferrite material properties
• Designed for compact surface-mount integration in space-constrained circuits
• Capable of handling significant direct current without saturation

Applications

• General signal line filtering
• Power supply output filtering
• High-speed data line noise suppression

Procurement Notes

Verify the specific suffix CT000 against official TDK documentation to confirm tape-and-reel packaging specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit design.

Selection Notes

Select this component when a 0402 footprint is required for noise suppression. The 1.2 A current rating suits moderate power applications. Verify that the 120 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum for effective attenuation.

Part Context

This part belongs to the MPZ series of ferrite beads, which are widely used for EMI suppression. The 1005 metric case size is standard for general-purpose electronics. It serves as a passive component to dampen high-frequency interference in electronic assemblies.

Replacement Considerations

Cross-reference with other 0402 ferrite beads offering similar 120 Ohm impedance and 1.2 A current ratings. Verify pin compatibility and thermal characteristics before substitution.
