Z0402C221APMST

Overview

The KEMET Z0402C221APMST is a ferrite bead from the Z-PMS series designed for power line noise suppression. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 220 ohms at its rated frequency, supports a maximum current of 800 mA, and exhibits a DC resistance of 0.2 ohms with a tolerance of ±25%.

Feature Summary

• Provides effective high-frequency noise attenuation on power lines through ferrite material properties
• Designed for compact surface-mount integration in space-constrained electronic assemblies
• Engineered to maintain stable performance under specified direct current loads

Applications

• Power line filtering in portable consumer electronics
• Noise suppression in automotive infotainment systems
• Signal integrity management in industrial control modules

Procurement Notes

Verify the specific impedance curve and current rating requirements against the official KEMET datasheet for the Z-PMS series. Confirm that the 0.2 ohm DC resistance aligns with the target circuit's voltage drop constraints. Ensure the 800 mA continuous current capability meets the operational load conditions without thermal degradation.

Selection Notes

Select this component when a low-profile 0402 footprint is required for power rail decoupling. The 220 ohm impedance value targets common switching noise frequencies. Consider the ±25% tolerance for impedance variations during design margin calculations. Evaluate the 0.2 ohm DCR impact on overall power efficiency relative to alternative solutions.

Part Context

This ferrite bead belongs to KEMET’s Z-PMS series, which focuses on power management applications requiring robust noise suppression in small form factors. The Z-PMS line complements other passive components by offering specialized magnetic materials optimized for high-current environments while maintaining strict dimensional standards for automated assembly processes.
