Z0603C182DSMST

Overview

The KEMET Z0603C182DSMST is a ferrite chip bead in the Z-SMS series, designed for surface mount technology. It features a 0603 (1608 metric) package with dimensions of 1.6 mm length and 0.8 mm width. The component provides an impedance of 1800 ohms at 100 MHz with a tolerance of 25%. It supports a maximum DC current rating of 0.2 A and has a maximum DC resistance of 0.85 ohms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high impedance filtering for noise suppression in compact designs
• Supports surface mount assembly for automated manufacturing processes
• Maintains stable performance across a wide industrial temperature range

Applications

• High-frequency signal line noise suppression
• Power supply output filtering
• EMI/RFI attenuation in compact electronic modules

Procurement Notes

Verify the specific suffix SMST against official KEMET documentation to confirm packaging and material specifications. Ensure the selected variant matches the required impedance and current ratings for the target circuit design. Cross-reference the manufacturer part number with authorized distributors to confirm availability and authenticity before procurement.

Selection Notes

Select this component when high impedance at 100 MHz is required within a 0603 footprint. Evaluate the 0.2 A current rating to ensure it meets the circuit's operational demands without saturation. Consider the low DC resistance of 0.85 ohms for minimal voltage drop in power lines. Confirm compatibility with standard SMT reflow processes.

Part Context

This ferrite bead belongs to KEMET's Z-SMS series of passive components. It is categorized under ferrite chip beads used for electromagnetic interference suppression. The 0603 case size allows for dense PCB layouts. It serves as a critical element for maintaining signal integrity in high-speed digital and RF applications by attenuating unwanted high-frequency noise.

Replacement Considerations
