Overview
The KEMET Z0402C431ASMST is a ferrite chip bead from the Z-SMS series, designed for surface mount technology in a 0402 (1005 metric) package. It provides an impedance of 430 Ohms with a tolerance of 25%, measured at a test frequency of 100 MHz. The component supports a maximum DC current of 350 mA and exhibits a maximum DC resistance of 450 mOhms. It operates within a temperature range of -55°C to +125°C and features shielded construction.
Feature Summary
- Provides high impedance attenuation for noise suppression in high-frequency circuits
- Shielded design minimizes electromagnetic interference coupling
- Compact 0402 footprint suitable for space-constrained layouts
Applications
- High-speed digital signal line filtering
- Power supply output noise reduction
- RF circuit interference suppression
Procurement Notes
Verify end-of-life status as the manufacturer indicates this model is scheduled for obsolescence. Confirm availability through authorized distributors before finalizing designs. Ensure RoHS compliance documentation is obtained. Check for alternative sourcing options due to potential supply constraints associated with discontinued components.
Selection Notes
Select this component when a 430 Ohm impedance at 100 MHz is required within a 0402 package. Verify that the 350 mA current rating meets the application's DC load requirements. Consider the 450 mOhms DCR impact on voltage drop. Evaluate thermal performance within the specified -55°C to +125°C operating range for environmental suitability.
Part Context
This ferrite bead belongs to KEMET's Z-SMS series, which offers commercial-grade components in standard SMD packages. The series focuses on providing reliable EMI suppression solutions for general electronic applications. The Z0402C431ASMST specifically addresses noise control needs in compact consumer and industrial electronics requiring standardized form factors.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Consult KEMET technical support or authorized distributors for verified cross-reference information regarding equivalent impedance and current ratings.
