Z0402C330APMST

Overview

The KEMET Z0402C330APMST is a ferrite chip bead in the Z-SMS series, housed in a 0402 (1005 metric) SMD/SMT package. It offers an impedance of 33 ohms with a maximum DC current rating of 1.7 A and a maximum DC resistance of 50 milliohms. The component operates within a temperature range of -55°C to +125°C and features a 25% tolerance.

Feature Summary

• Provides high-current suppression capabilities for noise filtering applications
• Utilizes a compact surface-mount design for space-constrained PCB layouts
• Ensures stable performance across a wide industrial temperature range

Applications

• High-current signal line noise suppression
• Power supply output filtering
• Data bus protection in compact electronic devices

Procurement Notes

Verify the specific suffix 'PMST' against official KEMET documentation to confirm the 1.7A current rating and 50mOhm DCR specifications. Ensure compatibility with standard 0402 reflow soldering profiles. Confirm end-of-life status if applicable, as availability may be limited compared to active series components.

Selection Notes

Select this component when high current handling is required alongside low impedance noise filtering in small form factors. Compare against the Z0402C330CSMST for lower current options or other series variants for different impedance characteristics. Validate thermal management requirements given the 1.7A rating.

Part Context

This part belongs to the KEMET Z-SMS series of ferrite beads, designed for general-purpose EMI suppression. It complements other 0402 ferrite components by offering higher current capacity than standard variants, suitable for power integrity applications where space is limited.

Replacement Considerations

Check for direct substitutes within the Z-SMS series with matching 33-ohm impedance and similar current ratings. Verify pinout and footprint compatibility before replacing existing designs.
