Overview
The KEMET Z0402C241BSMST is a surface-mount ferrite bead designed for noise suppression in electronic circuits. It features a 0402 (1005 metric) package with an impedance of 240 ohms at 100 MHz and a maximum DC current rating of 300 mA. The component has a maximum DC resistance of 360 milliohms and a tolerance of 25%. It operates within a temperature range of -55°C to +125°C.
Feature Summary
- Provides electromagnetic interference suppression through high-impedance characteristics at target frequencies.
- Utilizes a compact 0402 footprint suitable for space-constrained printed circuit board layouts.
- Maintains low direct current resistance to minimize signal attenuation and power loss.
Applications
- High-speed data line filtering
- Power supply output decoupling
- Clock signal noise reduction
Procurement Notes
Verify the specific manufacturer part number against official KEMET documentation to ensure authenticity. Confirm that the component meets required RoHS compliance standards for the intended market. Check for any end-of-life notices or obsolescence warnings associated with this specific batch or revision before finalizing procurement plans.
Selection Notes
Select this component when a small form factor is required for EMI suppression on lines carrying currents up to 300 mA. Ensure the operating frequency aligns with the peak impedance point of the ferrite material. Verify that the low DC resistance meets the voltage drop requirements of the specific circuit design.
Part Context
This ferrite bead belongs to the Z-SMS series from KEMET, which focuses on general-purpose noise suppression solutions. The series offers various impedance values and current ratings within standard industrial packages to support diverse electronic design needs across consumer and industrial sectors.
Replacement Considerations
Consult official KEMET substitution guides for verified alternatives. Cross-reference impedance curves and current ratings to ensure functional equivalence. Do not assume compatibility based solely on package size or nominal impedance values without verifying detailed electrical specifications.
