Feature Summary

• Provides current compensated inductance for effective common mode noise suppression
• Designed for series connection with AC power phase or neutral lines
• Utilizes a toroidal ferrite core structure for magnetic performance

Applications

• AC power line filtering
• Electromagnetic interference (EMI) suppression
• Common mode noise reduction in electronic equipment

Procurement Notes

Verify the specific part number RN142-6-02-1M8 against official TE Connectivity / Schaffner documentation to confirm current availability and specifications. Ensure that the ordering suffix corresponds to the required functional parameters as defined in the manufacturer's datasheet. Cross-reference technical details with authorized distributors to prevent procurement errors related to variant differences.

Selection Notes

Select this component for applications requiring horizontal PCB mounting and high current handling up to 6 A. The 1.8 mH inductance at 10 kHz test frequency suits standard EMI filtering needs. Consider the 20 mOhm DCR for efficiency requirements and verify that the 33.1 mm footprint fits the design constraints. The unshielded construction requires appropriate layout considerations for magnetic coupling.

Part Context

This component belongs to the Schaffner RN series, which consists of wound inductors on toroidal ferrite cores. These chokes are designed to be connected in series with AC power lines to attenuate common mode or asymmetrical noise. The RN series offers various current ratings and inductance values to accommodate different power supply filtering requirements across industrial and commercial electronics.

Replacement Considerations

The part number alias 816530-SF may serve as a direct substitute. Verify compatibility with other RN series variants such as RN143-6-02-1M8 by comparing inductance, current rating, and physical dimensions before implementation.
