Procurement Notes
Verify the specific manufacturer part number against official TE Connectivity or Schaffner documentation to confirm compatibility. Ensure that the required inductance value and current ratings align with your circuit design specifications before procurement. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.
Selection Notes
Select this component when a 15 mH inductance is required for common mode noise attenuation at low frequencies. The 0.5 A current rating suits applications with moderate power consumption. Consider the physical footprint of 18 mm by 12.5 mm for PCB layout constraints. Verify thermal performance within the specified operating temperature range.
Part Context
This component belongs to the RN series of common mode chokes from Schaffner EMC Inc., now part of TE Connectivity. The series offers various inductance and current combinations for different filtering needs. These components are engineered for reliable performance in demanding electronic environments.
Replacement Considerations
Check for direct substitutes within the RN series with similar inductance and current ratings. Verify pinout compatibility and physical dimensions to ensure seamless integration into existing designs without PCB modifications.
