Overview
The Schaffner RN142-2-02-6M8 is a horizontal through-hole common mode choke from the RN series. It features an inductance of 6.8 mH with a tolerance of -30% to +50%. The component supports a maximum DC current of 2 A and has a maximum DC resistance of 192 mΩ. It operates within a temperature range of -40°C to +100°C and utilizes ferrite core material.
Feature Summary
- Provides effective attenuation of common mode electromagnetic interference signals
- Utilizes a horizontal mounting configuration for compact PCB integration
- Constructed with ferrite core material for stable magnetic performance
Applications
- General-purpose EMI filtering in electronic equipment
- Power supply input stages requiring common mode noise suppression
- Signal lines needing interference reduction in industrial environments
Procurement Notes
Verify the specific manufacturer designation, as TE Connectivity acquired Schaffner EMC. Confirm that the part number RN142-2-02-6M8 corresponds to the required 6.8 mH inductance and 2 A current rating. Ensure compatibility with horizontal PCB mounting requirements and verify RoHS compliance status for your region.
Selection Notes
Select this component when a high inductance value of 6.8 mH is required for low-frequency noise suppression. The 2 A current rating suits moderate power applications. Consider the horizontal package profile for space-constrained boards where vertical height must be minimized compared to standard radial or axial chokes.
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 offers various inductance and current ratings designed for general EMI/RFI suppression in electronic circuits, providing a cost-effective solution for noise filtering applications.
