Overview
The SCM20-102T-RC is a surface mount common mode choke manufactured by Allied Components International. It features two lines and operates within a temperature range of -40°C to +105°C. The component has a current rating of 230mA and an impedance of 1k Ohm.
Feature Summary
- Surface mount construction for automated assembly
- Dual-line configuration for common mode noise suppression
Applications
- USB 2.0 interface protection
- Signal line filtering in electronic circuits
Procurement Notes
Verify the specific suffix 'T' against the manufacturer's official documentation to confirm tape-and-reel packaging requirements. Ensure the impedance value of 1k Ohm matches the design specifications, as variations exist within the SCM20 series. Cross-reference the current rating of 230mA with thermal constraints in the final application environment.
Selection Notes
Select this component when a compact surface mount solution is required for dual-line signal integrity. The 1k Ohm impedance at high frequencies targets common mode interference typical in digital data lines. Verify that the 230mA current handling capacity meets the operational load without saturation.
Part Context
This part belongs to the SCM20 series of surface mount common mode chokes from Allied Components International. The series includes variants with different impedance values and current ratings, such as the SCM20-900T-RC and SCM20-121M-RC, designed for various USB and signal filtering applications.
Replacement Considerations
Check for direct substitutes like the SCM20-121M-RC if lower impedance is acceptable. Verify pin compatibility and physical dimensions against other manufacturers' offerings in the same package style.
