Procurement Notes

Verify the specific ordering suffix to ensure correct inductance and current ratings, as variations exist within the B82733 series. Confirm RoHS compliance status and lead-free characteristics during sourcing. Cross-reference the manufacturer's official datasheet for the exact electrical parameters corresponding to the full part number to avoid selection errors based on generic family data.

Selection Notes

Select this component when a common mode choke with 39 mH inductance and 1.2 A current handling is required. Ensure the application operates within the 250 V AC rated voltage limit. Verify that the through-hole mounting style fits the PCB layout constraints. Check thermal performance requirements against the +40 °C rated current specification.

Part Context

This component belongs to the B82733F/V series of power line chokes from EPCOS, now part of TDK Electronics. These devices are designed for electromagnetic interference suppression in AC power lines. The series utilizes current-compensated frame cores to minimize external magnetic fields while providing effective common mode noise attenuation for sensitive electronic applications.

Replacement Considerations

Direct substitutes include other B82733 series variants with matching 39 mH inductance and 1.2 A current ratings, such as B82733V2122B001 equivalents from authorized distributors. Verify mechanical dimensions and pinout compatibility before substitution.
