Z0402C330CSMST

Overview

The KEMET Z0402C330CSMST is a ferrite chip bead from the Z-SMS series, designed for surface-mount technology in a 0402 (1005 metric) package. It provides an impedance of 33 ohms with a maximum DC current rating of 400 mA and a tolerance of 25%. The component features a maximum DC resistance of 300 milliohms and operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics at target frequencies
• Supports automated assembly via standard SMD/SMT termination types
• Maintains stable performance across a wide industrial temperature range

Applications

• High-frequency noise filtering in compact electronic circuits
• Signal integrity protection on data lines requiring small form factors
• Power line conditioning for low-current sensitive components

Procurement Notes

Verify end-of-life status before finalizing designs, as this specific part number is listed as obsolete by the manufacturer. Confirm that alternative sourcing channels can supply genuine units if production continuity is required. Check datasheet revisions for any updated handling or mounting specifications prior to implementation.

Selection Notes

Select this component when a 33-ohm impedance value is specifically required for noise attenuation in space-constrained layouts. Ensure the circuit current does not exceed the 400 mA limit to prevent saturation. Consider the 0402 footprint compatibility with existing PCB silkscreens and pad designs during the integration phase.

Part Context

This ferrite bead belongs to the Z-SMS series, which focuses on providing reliable EMI suppression in miniature packages. The Z0402C330CSMST represents a specific impedance variant within this family, tailored for applications demanding precise filtering characteristics in a standard 0402 footprint.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the obsolete status.
