Overview
The KEMET Z0402C121APMST is a single-line ferrite chip bead designed for noise suppression in surface-mount applications. It features a 0402 (1005 metric) package with dimensions of 1.00mm length and 0.50mm width. The component provides an impedance of 120 Ohms at 100 MHz and supports a maximum DC current of 1A. Its maximum DC resistance is 140 milliohms, with a tolerance of 25%. The device operates within a temperature range of -55°C to +85°C.
Feature Summary
- Provides effective high-frequency noise attenuation for power lines
- Compact 0402 footprint suitable for space-constrained designs
- Capable of handling high continuous DC currents
Applications
- Power line filtering in portable electronics
- Noise suppression in automotive electronic modules
- Signal integrity management in industrial control systems
Procurement Notes
Verify the specific suffix 'PMST' against official KEMET documentation to confirm packaging and material specifications. Confirm end-of-life status and last-time-buy dates prior to design finalization. Ensure compatibility with standard reflow soldering profiles for 0402 components. Validate that the 1A current rating meets the application's peak load requirements without excessive thermal rise.
Selection Notes
Select this component when a compact ferrite bead is required for power rail filtering. The 120 Ohm impedance at 100 MHz targets common EMI frequencies. The 1A current rating distinguishes it from lower-current signal line beads. Consider the 140 milliohm DCR impact on voltage drop for low-voltage circuits. The 0402 size offers a balance between performance and board real estate.
Part Context
This part belongs to the KEMET Z-SMS series of ferrite beads. The series focuses on providing reliable noise suppression solutions for various electronic environments. The Z0402C base indicates the 0402 package and core material characteristics. The suffix defines specific terminal and packaging attributes.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult KEMET technical support or authorized distributors for qualified alternatives if this discontinued part is required.
