Overview
The KEMET Z0402C330FPMST is a surface-mount ferrite bead designed for high-frequency noise suppression in compact electronic circuits. It features a 33-ohm impedance at 100 MHz and supports a maximum DC current of 400 mA with a typical DC resistance of 300 milliohms. The component utilizes a standard 0402 (1005 metric) package, measuring 1.0 mm by 0.5 mm, ensuring compatibility with automated pick-and-place assembly processes. It operates reliably within a temperature range of -55°C to +125°C and meets RoHS compliance standards for environmental safety.
Feature Summary
- Provides effective attenuation of high-frequency electromagnetic interference signals
- Compact 0402 footprint enables dense circuit board layout optimization
- Low DC resistance minimizes power loss in signal paths
- Thermal stability ensures consistent performance across wide operating temperatures
Applications
- High-speed digital signal line filtering
- Power supply output noise suppression
- RF circuit impedance matching and isolation
Procurement Notes
Verify the specific suffix FPMST against official KEMET documentation to confirm terminal configuration and material composition. Ensure the procurement channel provides valid traceability records. Confirm that the delivered components match the specified RoHS status and packaging format required for your manufacturing process.
Selection Notes
Select this component when space constraints require a 0402 package size while maintaining adequate current handling capabilities. Evaluate the 33-ohm impedance value against the target frequency spectrum to ensure effective noise attenuation. Consider the low DC resistance characteristic to minimize voltage drop in sensitive power or signal lines.
Part Context
This ferrite bead belongs to KEMET's general-purpose chip bead series, engineered for broad commercial and industrial applications. The Z-series design focuses on balancing impedance performance with physical miniaturization. It serves as a critical passive component for maintaining signal integrity in modern high-density electronics.
Replacement Considerations
Consult official KEMET substitution guides for verified alternatives. Cross-reference impedance curves and current ratings when evaluating competitor parts to ensure functional equivalence.
