Z0402C330ASMST

Overview

The KEMET Z0402C330ASMST is a multilayer ferrite chip bead in the Z-SMS series, housed in a 0402 (1005 metric) surface-mount package. It provides an impedance of 33 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 700 mA and features a maximum DC resistance of 60 mOhms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer construction for compact high-frequency noise suppression
• Shielded design to contain magnetic fields
• Single-channel configuration for signal line filtering

Applications

• High-speed data line filtering
• Clock signal noise attenuation
• Power supply decoupling in compact layouts

Procurement Notes

Verify end-of-life status before finalizing designs, as this model is subject to obsolescence. Confirm RoHS compliance details through official documentation. Ensure availability aligns with production timelines due to potential supply constraints associated with discontinued components.

Selection Notes

Select this component when space is limited to a 0402 footprint and specific 33 Ohm impedance at 100 MHz is required. Evaluate the 700 mA current rating against circuit load requirements. Consider the 60 mOhms DCR for power loss calculations in low-voltage applications.

Part Context

This ferrite bead belongs to the Z-SMS series from KEMET, designed for commercial-grade applications. It utilizes multilayer technology to achieve effective electromagnetic interference suppression in small form factors suitable for dense printed circuit board assemblies.

Replacement Considerations

Check for direct substitutes within the same series or compatible impedance profiles. Verify that alternative components match the 0402 package dimensions and thermal characteristics.
