B82733F2901B001

Overview

The B82733F2901B001 is a current-compensated frame core double choke manufactured by EPCOS (TDK Electronics). It features a closed magnetic circuit with a ferrite frame construction and a PET coil former rated UL94 V-0. The component utilizes a 4-section winding directly on the core to achieve high inductance with low resistance. It is designed for power line applications with a rated voltage of 250 V AC and supports rated currents ranging from 0.7 A to 2.3 A at +40 °C. The rated inductance spans 10 mH to 100 mH, ensuring effective interference suppression.

Feature Summary

• Current-compensated frame core design providing a closed magnetic circuit for efficient operation
• High pulse-handling capability suitable for demanding power line environments
• Approximately 2% stray inductance enabling symmetrical interference suppression

Applications

• Power line chokes
• EMI suppression in AC circuits
• Industrial electronic equipment filtering

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 mounting configuration aligns with your PCB layout requirements. Ensure the thermal environment does not exceed the specified operating limits for the rated current. Check for any updated documentation regarding the transition from EPCOS to TDK branding to ensure accurate sourcing.

Selection Notes

Select this component when symmetrical interference suppression is critical due to its low stray inductance characteristics. The current-compensated design makes it ideal for applications requiring high inductance with minimal DC resistance. Consider the physical dimensions and the requirement for direct winding on the core if space constraints are a factor. Evaluate the rated current against the maximum expected load to ensure reliable performance under thermal stress.
