Overview
The KEMET Z0603C330ASMST is a multilayer ferrite chip bead from the Z-SMS series, designed for surface-mount applications. It provides an impedance of 33 Ohms at 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 1.2 A and features a maximum DC resistance of 80 mOhms. It operates within a temperature range of -55°C to +125°C and utilizes a 0603 (1608 metric) package.
Feature Summary
- Multilayer construction for compact signal line filtering
- High current handling capability up to 1.2 A
- Stable performance across extended industrial temperature ranges
Applications
- Signal line noise suppression in electronic circuits
- Electromagnetic interference (EMI) filtering
- Common mode noise reduction in high-speed data lines
Procurement Notes
Verify the specific part number suffix against official KEMET documentation to confirm exact impedance and current ratings. Confirm availability status as distribution channels may vary. Ensure the selected component meets the required thermal and electrical specifications for the target application environment before finalizing procurement.
Selection Notes
Select this component when a 0603 footprint is required for EMI suppression. Compare the 33 Ohm impedance value against the target noise frequency spectrum. Ensure the 1.2 A current rating exceeds the maximum operating current of the circuit to prevent saturation. Verify compatibility with standard SMT reflow processes.
Part Context
This ferrite bead belongs to the Z-SMS series, which offers various impedance values and current ratings in standard metric packages. It serves as a passive component for managing high-frequency noise in dense PCB layouts. The series is characterized by its multilayer technology, allowing for reliable performance in space-constrained designs.
Replacement Considerations
Check for direct substitutes within the Z-SMS series or other KEMET ferrite bead lines that match the 0603 package dimensions. Verify that alternative parts maintain equivalent impedance at 100 MHz and meet or exceed the 1.2 A current carrying capacity. Ensure thermal stability remains consistent across the specified operating temperature range.
