The component has an inductance of 68 mH with a tolerance of -30% to +50%. It supports a maximum DC current of 0.35 A and exhibits a maximum DC resistance of 4.4 Ohms. Rated for 250 V AC, the unit measures 21.5 mm in width, 13.5 mm in height, and 21.1 mm in length.

Feature Summary

• Current-compensated E-core double choke design for power line filtering
• Radial leaded termination for through-hole PCB mounting
• Ferrite core construction ensuring stable magnetic performance

Applications

• Power line chokes in electronic equipment
• Common mode noise suppression in industrial systems
• EMI filtering in automotive electronics

Procurement Notes

Verify the specific suffix 'A020' against the manufacturer's latest datasheet to confirm exact electrical tolerances and packaging details. Ensure the ordering part number matches the required inductance value of 68 mH and current rating of 0.35 A for your circuit design. Cross-reference RoHS compliance status if environmental regulations apply to your manufacturing process.

Selection Notes

Select this component when designing circuits requiring common mode rejection at low frequencies. The 68 mH inductance and 0.35 A current rating define its operational limits. Consider the radial package dimensions (21.5 x 13.5 mm) for PCB layout constraints. Verify that the 4.4 Ohm DC resistance aligns with your voltage drop requirements.

Part Context

This component belongs to the B82731T series of fixed inductors from EPCOS, now part of TDK Electronics. The series covers a range of inductances from 3.3 mH to 100 mH with varying current ratings up to 1.8 A. These chokes are designed for AC power line applications, offering compact E-core geometry suitable for space-constrained designs in consumer and industrial electronics.

Replacement Considerations

Check for direct substitutes within the B82731T family with matching 68 mH inductance. Verify that alternative parts maintain the same radial pin configuration and physical footprint to ensure compatibility with existing PCB layouts without mechanical modification.
