Z0402C181CSMST

Overview

The KEMET Z0402C181CSMST is a ferrite chip bead in the Z-SMS series, housed in a 0402 (1005 metric) SMD/SMT package. It provides an impedance of 180 ohms with a tolerance of 25%. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 530 milliohms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high-frequency noise suppression through ferrite material properties
• Designed for surface mount integration on printed circuit boards
• Constructed for commercial grade reliability applications

Applications

• High-speed data line filtering
• Power supply output noise reduction
• General purpose EMI suppression in compact electronics

Procurement Notes

Verify end-of-life status before finalizing designs, as this specific part number may be subject to obsolescence by the manufacturer. Confirm RoHS compliance details directly from the official datasheet. Ensure that the 300 mA current rating and 530 milliohm DCR align with the target circuit requirements to prevent performance degradation or thermal issues during operation.

Selection Notes

Select this component when a 0402 footprint is required for space-constrained layouts. The 180 ohm impedance value targets specific frequency ranges for noise attenuation. Verify that the 300 mA current handling capability exceeds the peak operating currents of the protected line to maintain effective filtering without saturation.

Part Context

This ferrite bead belongs to the Z-SMS series from KEMET, which focuses on standard commercial grade components. The series utilizes a monolithic ferrite structure optimized for suppressing electromagnetic interference in digital and analog circuits. The 0402 package size allows for high-density mounting on modern PCBs.
