Procurement Notes
Verify the specific ordering suffix and package details against the official Bourns datasheet to ensure compatibility with your design requirements. Confirm that the 1.1 A current rating and 250 V voltage rating meet your system's operational limits. Check for RoHS compliance status if required by your manufacturing standards. Ensure the through-hole pitch matches your PCB layout specifications before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring common mode chokes for power lines. Consider the 5 mH inductance value for the target noise frequencies. Evaluate the 1.1 A current handling capability against peak load conditions. Verify the 280 mOhm DCR impact on power loss. Ensure the through-hole form factor fits the assembly process.
Part Context
This part belongs to Bourns' common mode inductor and EMI filter series. It is engineered for general-purpose noise suppression in power supply inputs. The product line focuses on providing reliable filtering solutions for various electronic equipment. Bourns manufactures these components to meet industry standards for electromagnetic interference reduction.
Replacement Considerations
Consult the official Bourns replacement guide or distributor cross-reference lists for verified substitute part numbers. Do not assume functional equivalence based solely on similar electrical parameters. Verify pinout, inductance tolerance, and current ratings before substituting.
