Overview
The Schaffner RN114-0.8-02-27M is a common mode filter choke designed for through-hole PCB mounting. It features a ferrite core and horizontal orientation with four PC pins. The component provides an inductance of 27 mH at a test frequency of 10 kHz, with tolerances of -30% to +50%. It supports a maximum DC current of 800 mA (0.8 A) and has a maximum DC resistance of 500 mOhms. Operating temperatures range from -40°C to +100°C. Physical dimensions are approximately 32.5 mm x 33.1 mm x 19.7 mm.
Feature Summary
- Horizontal through-hole construction with four PC pins for secure PCB integration
- Ferrite core design optimized for common mode noise suppression
- Current compensated choke architecture for efficient signal integrity
Applications
- Electromagnetic compatibility filtering in electronic circuits
- Power supply input stages requiring common mode noise reduction
- Signal line protection against high-frequency interference
Procurement Notes
Verify the specific manufacturer part number RN114-0.8-02-27M against official TE Connectivity/Schaffner documentation to ensure authenticity. Confirm that the horizontal package style and 4-pin configuration match your PCB footprint requirements. Check RoHS compliance status via the official datasheet before procurement.
Selection Notes
Select this component when a 27 mH inductance value is required for common mode applications with an 800 mA current rating. Ensure the board layout accommodates the horizontal form factor and the specified thermal operating range of -40°C to +100°C. Verify that the 500 mOhm DCR meets system power loss constraints.
Part Context
This component belongs to the RN series of common mode chokes manufactured by TE Connectivity under the Schaffner brand. The series offers various inductance and current ratings for different EMC filtering needs. The RN114 variant specifically targets applications requiring moderate current handling with significant noise attenuation capabilities.
Replacement Considerations
Publicly confirmed substitute part numbers for RN114-0.8-02-27M were not found in the provided source material. Consult official distributor databases or manufacturer cross-reference tools for potential alternatives.
