Procurement Notes
Verify the manufacturer designation, as some listings identify Qnity while others cite Laird-Signal Integrity Products. Confirm the specific package type and lead times directly with suppliers, as availability data varies across distributors. Ensure the component meets RoHS compliance requirements for your specific project needs before finalizing procurement.
Selection Notes
Select this component when a through-hole solution is required for high-current power lines. The 130 Ohm impedance at 100 MHz targets specific noise frequencies. Verify that the 10 A current rating and 10 mOhm DCR align with the circuit's electrical demands and thermal management capabilities.
Part Context
This part belongs to the Laird CM series of common mode chokes. The series is characterized by small form factors and high performance, offering economical solutions for common mode filtering. It serves as a specialized passive component within the broader category of inductors, chokes, and coils used for signal integrity and power conditioning.
Replacement Considerations
The CM4545Z131R-10 is a related variant within the same series. Differences may exist in physical dimensions or lead configuration. Verify compatibility with existing footprints and electrical specifications before substitution.
