Overview
The SCM10-102M-RC is a surface-mount common mode choke manufactured by Allied Components International. It is designed for USB 2.0 applications, providing electromagnetic interference suppression on differential data lines. The component features a horizontal package with four PC pads for secure mounting. Key electrical specifications include an impedance of 1000 Ohms at 100 MHz and a DC resistance (DCR) of 300 milliohms. These characteristics ensure effective noise filtering while maintaining signal integrity in high-speed digital interfaces.
Feature Summary
- Designed specifically for USB 2.0 interface protection
- Provides common mode noise suppression on differential pairs
- Utilizes a compact horizontal surface-mount package
Applications
- USB 2.0 port filtering
- Data line EMI suppression
- Portable electronic device input stages
Procurement Notes
Verify the specific impedance value and DC resistance against the official datasheet before integration. Confirm that the horizontal package dimensions match the target PCB footprint. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability. Check for any recent revisions to the part number suffix that may indicate packaging or material changes.
Selection Notes
Select this component when designing circuits requiring robust common mode rejection for USB 2.0 signals. The low DC resistance minimizes voltage drop across the data lines. The specified impedance at 100 MHz aligns with standard USB 2.0 frequency requirements. Consider thermal management if multiple units are placed in close proximity on the board.
Part Context
This part belongs to the SCM10 series of common mode chokes from Allied Components International. Similar models in the series, such as the SCM10-670M-RC and SCM10-300M-RC, offer different impedance values for varying noise profiles. The series is characterized by its suitability for high-density PCB layouts and compliance with common electromagnetic compatibility standards for consumer electronics.
Replacement Considerations
Direct substitutes within the same series include the SCM10-670M-RC and SCM10-501M-RC, which share similar physical footprints but differ in impedance ratings. Verify that alternative components meet the same DCR and current handling requirements to maintain circuit performance.
