Z0402C221BPMST

Overview

The KEMET Z0402C221BPMST is a ferrite chip bead from the Z-PMS series, designed for noise suppression in surface-mount applications. It features a 0402 (1005 metric) package with standard SMD/SMT termination. The component provides an impedance of 22 ohms at a maximum DC current rating of 600 mA. Its maximum DC resistance is specified as 180 milliohms. The device operates within a temperature range of -55°C to +125°C and carries a tolerance of 25%.

Feature Summary

Provides effective high-frequency noise suppression through ferrite material properties
Compact 0402 footprint suitable for space-constrained surface-mount designs
Low DC resistance minimizes voltage drop and power loss in signal paths

Applications

High-speed data line filtering
Clock signal noise attenuation
General-purpose EMI suppression in compact electronics

Procurement Notes

Verify the specific impedance value against official datasheets, as conflicting public records exist regarding whether this part number corresponds to 22 ohms or 180 ohms. Confirm the manufacturer's current production status, as similar Z-series parts have been marked obsolete in some distributor databases. Ensure the selected variant matches the required DC current rating for the target circuit application.

Selection Notes

Select this component when low profile and minimal insertion loss are critical requirements. The 0402 size allows for dense PCB layouts. Evaluate the impedance frequency characteristics to ensure adequate attenuation at the specific noise frequencies encountered. Compare the 180 milliohm DCR against allowable voltage drop limits in the design.

Part Context

This part belongs to KEMET's Z-PMS ferrite bead family, which focuses on noise suppression for portable and industrial devices. The Z-series utilizes specialized ferrite materials optimized for broadband attenuation. The 0402 form factor represents a standard industry size for general-purpose filtering components.
