RN212-0.8-02-10M

Overview

The RN212-0.8-02-10M is a vertical through-hole common mode choke manufactured by TE Connectivity / Schaffner. It features a ferrite core and operates within a temperature range of -40°C to +100°C. The component provides an inductance of 10 mH with a tolerance of -30% to +50%, tested at 10 kHz. It supports a maximum DC current of 0.8 A and has a maximum DC resistance of 380 mOhms. The physical dimensions are 17.7 mm x 17.1 mm x 12.6 mm, and it is unshielded.

Feature Summary

• Vertical PCB mount design for space-efficient integration
• Current compensated choke construction using ferrite core
• Through-hole termination for secure board attachment

Applications

• Electromagnetic interference suppression in electronic circuits
• Common mode noise filtering in power supply lines
• Signal integrity protection in data transmission interfaces

Procurement Notes

Verify the manufacturer part number against official TE Connectivity or Schaffner documentation to ensure authenticity. Confirm that the specific suffix matches the required electrical parameters, particularly the 10 mH inductance and 0.8 A current rating. Check for any alternate naming conventions such as 815797-SF if referenced in legacy designs. Ensure compliance with relevant RoHS directives before final procurement.

Selection Notes

Select this component when a compact, vertical-mount solution is required for common mode noise reduction. The 0.8 A current rating suits low-to-medium power applications. Verify that the 380 mOhm DC resistance meets the voltage drop requirements of the circuit. Ensure the operating environment stays within the specified -40°C to +100°C temperature range for reliable performance.

Part Context

This component belongs to the RN series of common mode chokes from Schaffner EMC Inc., now part of TE Connectivity. The series offers various inductance and current ratings in a standardized vertical package. These chokes are designed for general-purpose EMI filtering in consumer electronics and industrial equipment where board space is limited.

Replacement Considerations

Check for direct substitutes within the RN series with compatible inductance and current ratings. Verify pin compatibility and mechanical dimensions before substitution. No specific public substitute part numbers are confirmed for this exact model.
