The component has a rated AC voltage of 250 V at 50/60 Hz and an inductance of 82 mH. It supports a rated current of 0.5 A with a DC resistance of 31 mOhm. The operating temperature range spans from -40 °C to +125 °C, with specific rated temperatures available at +40 °C, +45 °C, +50 °C, +60 °C, and +70 °C.

Feature Summary

• Current-compensated design utilizing a ring core structure for power line filtering applications
• Vertical mounting configuration with four pins for secure through-hole integration
• High insulation capability with a test voltage of 1500 V AC between lines

Applications

• Power line chokes for AC mains filtering
• EMI suppression in electronic equipment input stages
• Common mode noise reduction in power supplies

Procurement Notes

Verify the specific rated temperature suffix required for your thermal environment, as the series offers options ranging from +40 °C to +70 °C. Confirm that the vertical package dimensions fit your PCB layout constraints. Ensure the 0.5 A current rating meets your circuit's maximum load requirements before finalizing procurement.

Selection Notes

Select this component when high inductance values are needed for effective common mode noise attenuation in single-phase AC applications. The vertical form factor aids in space-constrained designs where board height allows. Consider the specific rated temperature variant based on the ambient conditions of the installation site to ensure long-term reliability under thermal stress.

Part Context

This part belongs to the B82724A/J series of power line chokes designed for general-purpose electromagnetic interference suppression. The series is characterized by its robust ferrite core technology and compliance with international safety standards. These components are widely used in industrial and consumer electronics to protect circuits from conducted disturbances on the power line.

Replacement Considerations

Direct substitutes within the same series include B82724A2501N001, which shares identical electrical specifications but may differ in mechanical orientation or manufacturing batch variations. Verify pin compatibility and thermal ratings when cross-referencing with other manufacturers' equivalent common mode chokes.
