RN212-1.5-02

Overview

The Schaffner RN212-1.5-02 is a two-line common mode choke designed for through-hole PCB mounting. It features a ferrite core and operates within a temperature range of -40°C to +100°C. Key electrical parameters include an inductance of 3.3 mH at 1 kHz, a maximum DC current rating of 1.5 A, and a typical DC resistance of 135 mOhms. The component has a vertical orientation with dimensions of approximately 18 mm x 12.5 mm x 20 mm.

Feature Summary

• Provides common mode noise suppression for differential signal lines
• Utilizes a ferrite core for effective electromagnetic interference filtering
• Designed for vertical through-hole printed circuit board integration

Applications

• Power supply input filtering
• Signal line noise reduction in electronic equipment
• EMI suppression in industrial control systems

Procurement Notes

Verify the specific suffix designation (e.g., -3M3) required for your assembly, as the base part number may refer to a legacy or obsolete configuration. Confirm that the 1.5 A current rating and 3.3 mH inductance meet your circuit's operational requirements. Ensure the vertical through-hole package fits your PCB footprint constraints. Check for RoHS compliance status if mandated by your project specifications.

Selection Notes

Select this component when a 1.5 A rated common mode choke with 3.3 mH inductance is needed for vertical PCB mounting. Compare the 135 mOhm DC resistance against your voltage drop limitations. Consider the -40°C to +100°C operating range for environmental suitability. Evaluate alternative RN212 series variants if different current or inductance values are required.

Part Context

This component belongs to the Schaffner RN series of common mode chokes, manufactured under TE Connectivity / Schaffner. The RN212 series offers various current and inductance combinations for EMI filtering applications. This specific model represents a standard vertical through-hole option within that family, distinct from horizontal variants like the RN112 series.

Replacement Considerations

Public sources indicate that the RN212-1.5-02 is obsolete and no longer manufactured. Substitutes such as the RN212-1.5-02-3M3 may be available. Verify pin compatibility and electrical equivalence before replacing.
