Procurement Notes
Verify the specific part number against official Bourns documentation to confirm electrical ratings and physical dimensions. Ensure the procurement specification matches the required inductance and current handling capabilities for the target application. Confirm RoHS compliance status if environmental regulations apply to the end product assembly process.
Selection Notes
Select this component when a radial leaded form factor is required for high-current common mode filtering. The 2 A rating suits moderate power applications where through-hole mounting provides mechanical stability. Consider the 850 µH value for standard EMI frequencies. Verify board space constraints against the specified footprint dimensions before finalizing the design.
Part Context
This component belongs to the Bourns 7100 series of common mode chokes. The series offers various inductance values and current ratings in a radial leaded package. The 7107-RC variant specifically targets applications requiring 850 µH inductance at 2 A. It serves as a passive filter element for electromagnetic interference reduction in electronic circuits.
Replacement Considerations
Cross-reference with other Bourns 71xx-RC series parts for alternative inductance or current ratings. Verify pin compatibility and thermal characteristics when substituting with components from different manufacturers.
