Procurement Notes
Verify the manufacturer part number matches TE Connectivity / Schaffner RN114-1.2-02-10M exactly. Confirm the package type is horizontal with four pins. Ensure the inductance value is 10 mH and rated current is 1.2 A. Check RoHS compliance status if required by your specific application standards. Cross-reference the datasheet for tolerance specifications before finalizing procurement.
Selection Notes
Select this component when horizontal mounting is preferred for low-profile designs. The 1.2 A rating suits moderate current applications requiring significant inductance. Verify that the 195 mOhm resistance fits your power loss constraints. Ensure the operating temperature range meets your environmental requirements. Compare physical dimensions against available PCB real estate to confirm fitment.
Part Context
This component belongs to the Schaffner RN series of EMC/RFI chokes. The series is designed for general-purpose electromagnetic compatibility filtering. These components are widely used in industrial and commercial electronics to suppress conducted emissions. The RN series offers various current ratings and inductance values to suit different circuit requirements.
Replacement Considerations
Check for direct substitutes within the RN series with similar inductance and current ratings. Verify pinout compatibility and physical dimensions before substitution. Ensure the replacement component meets the same thermal and electrical specifications.
FAQ
What is the inductance tolerance for this component?
