Overview
The SMB40-RC is a surface mount ferrite bead manufactured by Allied Components International. It features a 2-SMD J-Lead package designed for high-current applications. The component exhibits an impedance of 90 Ohms at 100 MHz and a maximum DC resistance of 900 milliohms. It supports a current rating of 8 Amperes, providing effective electromagnetic interference suppression in compact circuit layouts.
Feature Summary
- Provides electromagnetic interference filtering through high-frequency impedance characteristics
- Supports high continuous current operation suitable for power line applications
- Utilizes a compact surface mount J-Lead package for automated assembly
Applications
- Power supply output filtering
- High-speed data line noise suppression
- General-purpose EMI suppression in consumer electronics
Procurement Notes
Verify the manufacturer designation as Allied Components International to ensure component authenticity. Confirm that the specific suffix RC aligns with your project requirements regarding material composition or tolerance specifications. Cross-reference the 90 Ohm impedance value against your target frequency range to validate performance suitability before finalizing procurement orders.
Selection Notes
Select this component when an 8 Ampere current capacity is required alongside significant attenuation at 100 MHz. The low DC resistance minimizes voltage drop across the component in power paths. Ensure the PCB footprint accommodates the 2-SMD J-Lead configuration to maintain proper mechanical stability and electrical connectivity during operation.
Part Context
This ferrite bead belongs to the SMB series from Allied Components International, which offers various impedance values for different noise profiles. The SMB40-RC specifically targets applications requiring robust current handling capabilities while maintaining effective high-frequency signal integrity. It serves as a passive filter element within broader electronic systems.
Replacement Considerations
Consult official distributor databases for direct substitutes with identical 90 Ohm impedance and 8A current ratings. Verify that any alternative part maintains the same 2-SMD J-Lead package dimensions to ensure compatibility with existing board layouts without redesign.
