Z0402C100ASMST

Overview

The KEMET Z0402C100ASMST is a ferrite chip bead in the Z-SMS series, designed for surface mount technology. It features an impedance of 10 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 1A and has a maximum DC resistance of 50 mOhms. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1 mm in length, 0.5 mm in width, and 0.5 mm in height, conforming to the 0402 (1005 metric) package. This single-channel shielded device is classified as commercial grade.

Feature Summary

• Provides electromagnetic interference suppression through high-frequency impedance characteristics.
• Utilizes a compact 0402 surface mount footprint for space-constrained circuit layouts.
• Features shielded construction to contain magnetic fields and reduce crosstalk.

Applications

• High-speed digital signal line filtering
• Power supply noise attenuation in portable electronics
• EMI suppression in consumer communication devices

Procurement Notes

Verify end-of-life status prior to procurement, as this component is scheduled for obsolescence. Confirm that the manufacturer will discontinue production. Ensure design-in timing accounts for final availability windows. Validate RoHS compliance details against the latest official datasheet revision. Check for alternative sourcing options if long-term supply stability is required for the product lifecycle.

Selection Notes

Select this component when a low impedance value of 10 Ohms is required for high-current applications up to 1A. The 0402 package size suits dense PCB layouts. Consider the 25% impedance tolerance for budgeting noise suppression margins. Verify that the 50 mOhms DCR meets voltage drop constraints in the specific power rail or signal path application context.

Part Context

This part belongs to the KEMET Z-SMS series of ferrite beads. It shares the 0402 mechanical outline with other variants like Z0402C800ASMST but differs significantly in electrical parameters such as impedance and current rating. The series targets general commercial grade applications requiring standard EMI filtering solutions without automotive qualification requirements.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the end-of-life status, direct cross-referencing requires consulting official KEMET replacement guides or distributor-specific equivalent lists not contained in the source material.
