Z0201C121ASMST

Overview

The KEMET Z0201C121ASMST is a single-line ferrite bead in the Z-SMS series, housed in a compact 0201 (0603 metric) surface-mount package. It provides an impedance of 120 Ohms at 100 MHz with a maximum DC resistance of 500 milliohms and a rated current of 200 mA. The component operates within a temperature range of -55°C to +125°C and complies with RoHS 3 standards.

Feature Summary

• Provides high-frequency noise suppression for signal lines
• Compact 0201 footprint for space-constrained designs
• Low DC resistance minimizes power loss

Applications

• High-speed digital signal line filtering
• RF circuit noise attenuation
• Portable electronic device power integrity management

Procurement Notes

Verify the specific suffix ASMST against the manufacturer's latest datasheet to confirm material composition and compliance status. Confirm availability as this part may be subject to end-of-life notices or discontinuation. Ensure the selected distributor provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a small form factor is required for high-frequency noise suppression. The 200 mA current rating suits low-power signal lines rather than high-current power rails. Compare the 120 Ohm impedance profile against target noise frequencies to ensure effective attenuation without excessive signal degradation.

Part Context

This ferrite bead belongs to the KEMET Z-SMS series, designed for general-purpose noise suppression in compact electronics. It complements other passive components by managing electromagnetic interference in dense printed circuit board layouts.

Replacement Considerations
