Common Mode Chokes Feature Summary

• Provides high-current suppression for single-phase applications
• Utilizes radial through-hole termination for printed circuit board integration
• Constructed as an unshielded compensation choke

Common Mode Chokes Applications

• Single-phase power supply input filtering
• Electromagnetic interference suppression in industrial equipment
• Common mode noise reduction in AC power lines

Common Mode Chokes Procurement Notes

Verify the specific suffix codes against official Schurter documentation to ensure correct tolerance and lead configuration. Confirm that the 7.2 mH inductance and 32 A current rating align with the target circuit requirements. Check for RoHS compliance status and manufacturing origin details prior to finalizing procurement orders.

Common Mode Chokes Selection Notes

Select this component when designing single-phase systems requiring significant common mode attenuation at lower frequencies. The 32 A current capacity suits heavy-duty industrial loads. Ensure the PCB layout accommodates the 53 mm diameter footprint and 31 mm height clearance. Verify thermal management strategies given the 2.3 mOhm DC resistance under full load conditions.
