Procurement Notes
Verify the exact part number against manufacturer documentation to ensure compatibility with specific circuit requirements. Confirm that the 6 A current rating and 3.9 mH inductance align with design specifications. Check for RoHS compliance status if required by project standards. Ensure proper thermal management is considered given the operating temperature limits.
Selection Notes
Select this component when high current capacity and significant inductance are required for EMI filtering in through-hole designs. Consider the physical footprint constraints due to its larger size compared to surface-mount alternatives. Evaluate the 42 mΩ DC resistance impact on overall system efficiency. Verify that the 10 kHz test frequency meets the application's noise spectrum needs.
Part Context
This component belongs to the Schaffner RN series of common mode chokes, which are widely used in EMC/RFI suppression applications. The RN series is known for providing reliable noise filtering in various electronic equipment. This specific model represents a higher current variant within the series, distinguished by its 3.9 mH inductance and 6 A rating.
Replacement Considerations
Direct substitutes may include other Schaffner RN series models with similar electrical characteristics. Verify pinout compatibility and physical dimensions before substitution. Cross-reference with TE Connectivity datasheets as they manufacture the Schaffner brand components.
