Overview
The SCM20-161T-RC is a surface-mount common mode choke manufactured by Allied Components International. It is designed for signal line protection in high-speed digital interfaces, specifically supporting USB 2.0 standards. The component features two lines and operates within an ambient temperature range of -40°C to +105°C. It has a current rating of 310mA. The device utilizes a compact surface-mount package suitable for automated assembly processes.
Feature Summary
- Provides common mode noise suppression for differential signal pairs
- Engineered for compatibility with USB 2.0 interface requirements
- Supports operation across extended industrial temperature ranges
Applications
- USB 2.0 data line filtering
- Signal integrity enhancement in high-speed digital circuits
- Noise reduction in portable electronic devices
Procurement Notes
Verify the specific suffix 'T' against the manufacturer's official documentation to confirm tape-and-reel packaging configuration. Ensure the impedance value aligns with the target frequency requirements for the specific application circuit. Cross-reference the current rating with the actual operating conditions to prevent saturation. Confirm the package dimensions match the PCB footprint design.
Selection Notes
Select this component when designing for USB 2.0 compliance where space constraints require a surface-mount solution. Evaluate the 310mA current rating against the maximum expected load current. Consider the operating temperature range if the device will be used in environments exceeding standard commercial limits. Verify that the impedance characteristics meet the EMI suppression needs of the specific signal lines.
Part Context
This part belongs to the SCM20 series of common mode chokes from Allied Components International. The series includes variants with different impedance values and current ratings, such as the SCM20-121M-RC and SCM20-900T-RC. These components are generally intended for protecting high-speed data lines from electromagnetic interference while maintaining signal integrity.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Engineers should consult the manufacturer's official cross-reference tools or datasheets for verified alternatives.
