RN143-6-02

Overview

The Schaffner RN143-6-02 is a common mode choke from the RN series, designed for electromagnetic compatibility (EMC) applications. It features an inductance of 1.8 mH and supports a continuous current rating of 6 A. The component operates at a maximum voltage of 300 VDC and utilizes a horizontal through-hole PCB mounting configuration with two leads. It is rated for PD2 pollution degree and meets UL 94V-0 flammability standards.

Feature Summary

• Provides common mode noise suppression for differential signal lines
• Designed for board mount integration via through-hole technology
• Constructed to withstand specific pollution degree environments

Applications

• Power supply input filtering
• Battery charger circuits
• Portable electronic device power stages

Procurement Notes

Verify the exact part number suffix against official Schaffner documentation to ensure correct pinout and mechanical dimensions. Confirm that the 300 VDC rating aligns with your system's peak voltage requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the horizontal package style fits within your PCB layout constraints.

Selection Notes

Select this component when a 1.8 mH inductance is required for common mode noise reduction in low-voltage DC circuits. The 6 A current rating suits moderate power applications. Consider the horizontal lead form factor for specific board assembly orientations. Verify thermal performance under expected load conditions.

Part Context
