RN232-4-02-3M3

Overview

The Schaffner RN232-4-02-3M3 is a current-compensated common mode choke belonging to the RN series. It features an inductance of 3.3 mH and supports a maximum DC current of 4 A. The component has a maximum DC resistance of 46 mΩ and operates within a temperature range of -40°C to +100°C. Designed for through-hole mounting, it utilizes horizontal pad termination. The physical dimensions are 17.7 mm in length, 17.1 mm in depth, and 12.6 mm in height.

Feature Summary

Provides effective common mode noise suppression for differential signal lines
Current-compensated design minimizes impact on signal integrity
Robust construction suitable for demanding industrial environments

Applications

Industrial communication interfaces such as RS-485 and CAN bus
Data transmission lines requiring EMI protection
Automotive electronic control units

Procurement Notes

Verify the specific pin configuration and mechanical footprint against the official datasheet before integration. Confirm that the operating temperature range meets the environmental requirements of the final assembly. Ensure the maximum DC current rating exceeds the peak operational current of the protected circuit to prevent saturation.

Selection Notes

Select this component when high attenuation is required for low-current differential signals. The horizontal package orientation facilitates specific PCB layout constraints. Compare the 4 A current rating against the application's steady-state and transient loads. Consider the 46 mΩ resistance value regarding potential voltage drop effects in sensitive signal paths.

Part Context

This part belongs to the Schaffner RN series of current-compensated chokes. These components are engineered for electromagnetic compatibility in data and power lines. The RN series offers various inductance values and current ratings to suit different filtering needs across industrial and automotive sectors.

Replacement Considerations

Check for direct substitutes with identical 3.3 mH inductance and 4 A current handling. Verify compatible through-hole mounting styles and similar dimensional constraints. Ensure equivalent performance characteristics for the target frequency range.
