B82733V2701B001

Overview

The B82733V2701B001 is a current-compensated frame core double choke designed for power line applications. It features a closed magnetic circuit with a ferrite frame construction and PET coil former rated UL94 V-0. The component supports through-hole mounting and operates within an ambient temperature range of -40°C to +125°C. Key electrical specifications include a rated AC voltage of 250 V, a rated current of 0.7 A at +40°C, and a rated inductance of 100 mH measured at 10 kHz. The maximum DC resistance is specified as 1.81 Ohms.

Feature Summary

• Current-compensated design utilizing a closed magnetic circuit with frame construction made of ferrite
• PET coil former construction meeting UL94 V-0 flammability rating
• Four-section winding technique applied directly on the core structure
• Clearance and creepage distances exceeding 3 mm for enhanced safety isolation

Applications

• Power line filtering in industrial equipment
• EMI suppression in consumer electronics
• Noise reduction in automotive electronic systems
• Filtering in renewable energy inverters

Procurement Notes

Verify the specific suffix code against official EPCOS/TDK documentation to confirm exact electrical tolerances and material certifications. Ensure the procurement channel provides original manufacturer traceability. Confirm that the delivered components match the RoHS compliance status indicated in the latest datasheet revision. Cross-reference the manufacturing date code to ensure storage conditions have not compromised the integrity of the PET former or ferrite core properties prior to installation.

Selection Notes

Select this component when a high-inductance common mode choke is required for low-current AC line filtering. The 100 mH value at 10 kHz makes it suitable for suppressing higher frequency noise. The through-hole package facilitates robust mechanical attachment in environments subject to vibration. Consider the 0.7 A current rating to ensure the operating load does not exceed thermal limits, particularly in enclosed spaces where heat dissipation may be restricted compared to open-air conditions.

Part Context

This part belongs to the B82733 series of power line chokes manufactured by EPCOS, now integrated into TDK Electronics. The series utilizes current-compensated frame core technology to minimize external magnetic fields while providing effective differential mode attenuation. These components are widely used in mains-powered devices requiring compliance with electromagnetic compatibility standards. The integration of EPCOS into TDK has expanded the availability of these passive components across global supply chains.

Replacement Considerations

Direct substitutes must match the 100 mH inductance, 0.7 A current rating, and 250 V AC voltage specification. Verify that alternative parts maintain the same through-hole footprint and height constraints. Ensure replacement components offer comparable DC resistance and operate within the -40°C to +125°C temperature range. Check for identical clearance and creepage distances if safety isolation is critical.
