Z0402C102ASMST

Overview

The KEMET Z0402C102ASMST is a ferrite chip bead in the Z-SMS series, designed for surface-mount technology. It features an impedance of 1000 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 180 mOhms. Encased in a compact 0402 (1005 metric) package measuring 1 mm x 0.5 mm x 0.5 mm, it operates within a temperature range of -55°C to +125°C. This single-channel shielded device is classified as commercial grade.

Feature Summary

• Provides high-frequency noise suppression through significant impedance characteristics at 100 MHz.
• Utilizes a compact 0402 surface-mount footprint suitable for space-constrained circuit designs.
• Features shielded construction to minimize electromagnetic interference effects.

Applications

• High-speed digital signal line filtering
• Power supply input/output noise attenuation
• RF circuit interference suppression

Procurement Notes

Verify end-of-life status before finalizing design integration, as this component is scheduled for discontinuation by the manufacturer. Confirm that alternative sourcing options are available if long-term production support is required. Ensure compatibility with existing PCB footprints and reflow soldering profiles specified for the 0402 package size.

Selection Notes

Select this component when specific high-impedance noise filtering is required at 100 MHz within a limited board area. Evaluate the 300 mA current rating against peak operational loads to prevent saturation. Consider the commercial grade classification and operating temperature limits relative to the intended environmental conditions of the target application.

Part Context

This ferrite bead belongs to the Z-SMS series from KEMET, which focuses on small-form-factor components for modern electronics. The Z0402C102ASMST represents a specific impedance variant within this lineup, distinguished by its 1000 Ohm characteristic. It serves as a passive filter element in multi-component assemblies requiring targeted high-frequency attenuation.

Replacement Considerations

Public confirmed substitute part numbers are not provided in the source material due to the component's end-of-life status. Engineers should consult official distributor databases or manufacturer obsolescence notices for validated cross-references that match the 0402 package, 1000 Ohm impedance, and 300 mA current specifications.
