B82733F2122B001

Overview

The B82733F2122B001 is a current-compensated frame core double choke manufactured by EPCOS (TDK). It is designed for power line applications with a rated voltage of 250 V AC and a rated inductance range of 10 mH to 100 mH. The component supports rated currents from 0.7 A to 2.3 A at +40 °C. Construction features include a closed magnetic circuit with a ferrite frame, a PET coil former rated UL94 V-0, and sector winding with direct winding on the core. Clearance and creepage distances exceed 3 mm.

Feature Summary

• High inductance with low resistance characteristics
• Approximately 2% stray inductance for symmetrical interference suppression
• High pulse-handling capability
• Low profile design suitable for wave soldering

Applications

• Suppression of common-mode and differential-mode interferences
• Electronic ballasts for lamps
• High power switch-mode power supplies for consumer electronics

Procurement Notes

Verify the specific inductance value within the 10 mH to 100 mH range required for your application, as this series covers multiple variants. Confirm that the 250 V AC rating aligns with your system's voltage requirements. Ensure compliance with EN 60938-2 and UL 1283 standards is necessary for your target market. Check RoHS compatibility status if restricted substances are a concern. Validate thermal performance at the expected operating temperature.

Selection Notes

Select this component when symmetrical interference suppression is critical due to its low stray inductance. The frame core construction offers high pulse-handling capability suitable for demanding power environments. Consider the low height specification if vertical space is limited. Ensure the rated current meets the peak load requirements of the electronic ballast or power supply circuit.

Part Context

This part belongs to the B82733F series of current-compensated frame core double chokes. These components are engineered for electromagnetic compatibility in power line applications. The series utilizes ferrite materials for efficient magnetic coupling while maintaining electrical isolation through PET formers. They are widely used in consumer electronics and lighting systems requiring robust noise filtering.

Replacement Considerations

Cross-reference with other B82733F series parts for different inductance values. Verify pinout and mechanical dimensions match existing board layouts. Ensure equivalent approval ratings such as ENEC and UL are maintained for regulatory compliance.
