RN143-1-02-47M

Overview

The Schaffner RN143-1-02-47M is a current-compensated common mode choke from the RN series, designed for PCB mounting via through-hole termination. It features a single channel with an inductance of 47 mH and a maximum DC resistance of 890 mOhms. The component supports a maximum DC current of 1 A and operates within a temperature range of -40°C to +100°C. Constructed with a ferrite core, it provides effective electromagnetic interference suppression in AC power line applications.

Feature Summary

Provides current-compensated inductance using two windings on a toroidal ferrite core for common mode noise reduction
Designed for series connection with AC power phase or neutral lines to suppress asymmetric emissions
Utilizes a horizontal through-hole mounting style for direct printed circuit board integration

Applications

AC power input filtering for electronic equipment
Suppression of common mode noise in single-phase power lines
Electromagnetic compatibility enhancement in consumer and industrial electronics

Procurement Notes

Verify the specific part number suffix against official TE Connectivity/Schaffner documentation to ensure correct inductance and tolerance specifications. Confirm that the through-hole footprint dimensions match the target PCB layout. Check RoHS compliance status in the latest datasheet before procurement.

Selection Notes

Select this component when a high inductance value of 47 mH is required for significant common mode attenuation at low frequencies. Ensure the application current does not exceed the 1 A rating to prevent saturation. Verify that the horizontal form factor fits within the available enclosure space compared to radial alternatives.

Part Context

This component belongs to the Schaffner RN series of current-compensated chokes. These devices are engineered to minimize electromagnetic interference by canceling differential mode currents while presenting high impedance to common mode noise. The series offers various inductance values tailored for different power line filtering requirements.

Replacement Considerations

Consult official substitution guides for equivalent RN series parts with adjusted inductance or current ratings. Verify mechanical compatibility and electrical performance parameters before replacing with generic common mode chokes.
