Z0402C601BSMST

Overview

The KEMET Z0402C601BSMST is a ferrite chip bead in the Z-SMS series, housed in a 0402 (1005 metric) SMD/SMT package. It provides an impedance of 60 ohms with a maximum DC current rating of 700 mA and a tolerance of 25%. The component features a maximum DC resistance of 100 mOhms and operates within a temperature range of -55°C to +125°C. Physical dimensions are 1 mm in length, 0.5 mm in width, and 0.5 mm in height. It is classified as a commercial grade, shielded single-channel device tested at 100 MHz.

Feature Summary

• Provides electromagnetic interference suppression through high-frequency impedance characteristics
• Features a compact surface-mount design suitable for space-constrained PCB layouts
• Includes shielding to contain magnetic fields and reduce external coupling

Applications

• High-speed digital signal line filtering
• Power supply noise attenuation in portable electronics
• EMI suppression on data bus interfaces

Procurement Notes

Verify end-of-life status before finalizing designs, as this component may be obsolete or subject to discontinuation by the manufacturer. Confirm that the specific ordering suffix matches the required impedance and current ratings for your application. Ensure compatibility with standard reflow soldering profiles for 0402 packages. Check for RoHS compliance documentation if required by your regional regulations. Validate availability through authorized distributors due to potential supply constraints associated with legacy parts.

Selection Notes

Select this component when a 60-ohm impedance at 100 MHz is required for EMI suppression in small form factors. The 700 mA current rating supports moderate power lines without significant saturation. Consider the 100 mOhm DCR for minimal voltage drop applications. The commercial grade classification limits use to non-critical environments compared to automotive or industrial grades. Evaluate thermal performance within the specified -55°C to +125°C operating range.
