Z0402C680ESMST

Overview

The KEMET Z0402C680ESMST 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 68 ohms with a tolerance of 25%. The component supports a maximum DC current of 500 mA and features a maximum DC resistance of 170 milliohms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics at target frequencies.
• Designed for compact surface-mount integration using standard SMD/SMT termination methods.
• Constructed to withstand thermal stress across a wide industrial operating temperature range.

Applications

• Signal line filtering in electronic circuits
• Power supply noise attenuation
• High-frequency circuit protection

Procurement Notes

Verify component authenticity against official KEMET documentation due to end-of-life status. Confirm package dimensions and electrical parameters match design requirements. Check for authorized distribution channels to ensure quality assurance. Validate RoHS compliance details as specified in the datasheet. Review lifecycle notices for availability constraints.

Selection Notes

Select this component when a 68-ohm impedance is required for EMI suppression in space-constrained designs. Ensure the 500 mA current rating meets the application's load requirements. Consider the 0402 footprint compatibility with existing PCB layouts. Evaluate the 170 milliohm DC resistance impact on signal integrity or power loss.

Part Context
