SC03H471NB25

Overview

The SC03H471NB25 is a single-phase common mode choke manufactured by Vishay Sfernice, designed for mains filtering applications. It features an inductance of 47 mH and supports a rated current of 0.3 A at 250 V. The component utilizes copper winding on a ferrite toroid encapsulated in epoxy, providing effective suppression of asymmetrical noise. It operates within a temperature range of -40 °C to +125 °C and measures 18.0 mm x 18.0 mm x 12.5 mm.

Feature Summary

Phase opposition winding design effectively filters asymmetrical common mode noise
Copper winding on ferrite toroid encapsulated in durable epoxy case
Supports integration with Y-capacitors and X-capacitors to enhance EMC filter efficiency

Applications

Single-phase mains EMI filtering
Electromagnetic interference suppression in power lines
Noise reduction for 50 Hz AC circuits

Procurement Notes

Verify the specific suffix NB25 against official Vishay documentation to confirm exact electrical tolerances and mechanical dimensions. Ensure compatibility with required voltage ratings and thermal operating limits before integration into final assemblies.

Selection Notes

Select this component for applications requiring robust common mode noise suppression in single-phase environments. Consider the 47 mH inductance value and 0.3 A current rating to ensure adequate performance for the target circuit's electromagnetic interference requirements.
