Overview
The Schaffner RN214-1.2-02-10M is a current compensated common mode choke designed for printed circuit board mounting. It features a ferrite core and vertical through-hole termination style. The component provides an inductance of 10 mH per path with a maximum DC current rating of 1.2 A. Its maximum DC resistance is specified at 300 milliohms, and it operates within a temperature range of -40°C to +100°C. The physical dimensions are approximately 18 mm x 12.5 mm x 20 mm.
Feature Summary
- Provides effective attenuation of common mode electromagnetic interference signals in electronic circuits.
- Utilizes a current compensated design to maintain performance under varying load conditions.
- Constructed with a ferrite core material for efficient magnetic flux handling.
Applications
- Power supply input filtering stages
- EMI suppression in AC/DC converter modules
- Signal integrity protection in industrial control systems
Procurement Notes
Verify the specific part number against official TE Connectivity or Schaffner documentation to confirm electrical ratings and mechanical footprint compatibility. Ensure that the sourcing channel provides genuine components with traceable manufacturing data. Cross-reference the datasheet for precise thermal derating curves and safety certifications required for your specific end-use application.
Selection Notes
Select this component when a 10 mH common mode inductance is required for 1.2 A applications. Consider the vertical PCB mount form factor for space-constrained designs. Evaluate the 300 milliohm DC resistance impact on system efficiency. Confirm that the operating temperature range meets the environmental requirements of the target installation site.
Part Context
This component belongs to the RN series of common mode chokes manufactured by Schaffner EMC Inc., now part of TE Connectivity. The series is engineered for general-purpose EMI filtering in power electronics. The RN214 variant specifically targets applications requiring robust common mode noise suppression with moderate current handling capabilities.
Replacement Considerations
Consult official manufacturer substitution guides for verified equivalents. Ensure any replacement matches the 10 mH inductance, 1.2 A current rating, and vertical through-hole package dimensions. Verify compatibility with existing PCB footprints and regulatory approvals before implementation.
