B82733F2701B001

Overview

The B82733F2701B001 is a current-compensated frame core double choke from the EPCOS B82733F series. It features a closed magnetic circuit with a ferrite frame construction and PET coil former rated UL94 V-0. The component has a 4-section winding directly on the core, ensuring clearance and creepage distances greater than 3 mm. Rated for 250 V AC, it supports currents from 0.7 A to 2.3 A at +40 °C. This specific part offers an inductance of 100 mH with a maximum DC resistance of 85 Ohms.

Feature Summary

• Current-compensated design utilizing a closed magnetic circuit with a ferrite frame construction
• Direct winding on the core using a 4-section configuration on a UL94 V-0 rated PET former
• High insulation safety with clearance and creepage distances exceeding 3 mm

Applications

• Power line filtering in electronic equipment
• EMI suppression in AC power input stages
• Common mode noise reduction in industrial control systems

Procurement Notes

Verify the complete ordering code against official TDK/EPCOS documentation to ensure correct inductance tolerance and packaging specifications. Confirm that the rated voltage and current parameters align with the target application's electrical requirements. Check for RoHS compliance status as per the latest manufacturer declarations before finalizing procurement orders.

Selection Notes

Select this component when a current-compensated choke is required for differential mode noise suppression in power lines. Ensure the operating temperature range covers the expected self-heating conditions. Verify that the physical dimensions fit the available PCB space and that the through-hole mounting style matches the assembly process.

Part Context

This component belongs to the B82733F series of power line chokes manufactured by EPCOS, now part of TDK Electronics. The series is designed for common mode applications in AC power supplies. These chokes are widely used in consumer electronics and industrial devices to meet electromagnetic compatibility standards by attenuating high-frequency interference on power lines.

Replacement Considerations

Consult official TDK substitution guides for direct equivalents within the B82733F family. Verify pinout compatibility and mechanical footprint before replacing with alternative manufacturers' parts. Ensure any substitute meets the same UL certification and thermal performance criteria.
