Z0402C121BPMST

Overview

The KEMET Z0402C121BPMST is a single-line ferrite bead chip designed for noise suppression in surface-mount applications. It features a 0402 (1005 metric) package with an impedance of 120 Ohms at 100 MHz and a maximum DC resistance of 120 milliohms. The component supports a maximum DC current of 1.1 Amperes and operates within a temperature range of -55°C to +125°C. It carries a tolerance of 25% and complies with RoHS standards.

Feature Summary

• Provides effective high-frequency noise attenuation for signal and power lines
• Compact 0402 footprint enables dense circuit board layouts
• Low DC resistance minimizes voltage drop and power loss
• Robust thermal stability across extended industrial temperature ranges

Applications

• High-speed data line filtering
• Power supply noise suppression
• RF interference mitigation in compact electronics

Procurement Notes

Verify the specific suffix BPMST against official KEMET documentation to confirm the exact electrical ratings, particularly the 1.1A current rating and 120mOhm DCR. Ensure the intended application environment aligns with the specified operating temperature limits. Confirm availability status as manufacturing lifecycles may change without notice.

Selection Notes

Select this component when space constraints require a 0402 package size while maintaining significant current handling capabilities. The low DC resistance makes it suitable for power rails where efficiency is critical. Verify that the 120 Ohm impedance profile matches the target noise frequency spectrum of the design.
