Procurement Notes

Verify the specific suffix 'R' indicates the correct termination or packaging variant required for your assembly process, as suffixes may denote differences in reel specifications or plating rather than electrical function. Confirm RoHS compliance status with the manufacturer, as historical data suggests variations across product lines. Ensure the 10A current rating aligns with your circuit's peak load requirements to prevent saturation. Cross-reference the exact part number with official Laird documentation to confirm availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when dual-line common mode filtering is required for signals carrying up to 10 A. The 170 Ohm impedance at 100 MHz makes it suitable for suppressing high-frequency noise in sensitive digital and power lines. Consider the physical dimensions and mounting type to ensure compatibility with your PCB layout constraints. Compare the DCR value against voltage drop requirements in your specific application to ensure efficient power transmission without excessive heat generation.

Part Context

This component belongs to Laird-Signal Integrity Products' portfolio of electromagnetic interference filters. Common mode chokes are critical for maintaining signal integrity by attenuating unwanted differential noise that appears simultaneously on both lines. The CM2545X series represents a robust solution for applications demanding high current capacity alongside effective EMI suppression in space-constrained environments.

Replacement Considerations

Direct substitutes include the CM2545X171B-10, which shares similar electrical characteristics but may differ in termination style or packaging format. Verify mechanical fit and pinout compatibility before substitution. Other Laird components with matching 170 Ohm impedance and 10A rating should be evaluated for thermal performance and footprint alignment.
