Procurement Notes

Verify the specific part number against official EPCOS/TDK documentation to confirm exact electrical parameters such as inductance and current ratings, as these vary within the B82721 series. Ensure compatibility with wave soldering requirements if applicable. Confirm that UL and VDE approvals are required for the target market and application safety standards before procurement.

Selection Notes

Select this component for applications requiring current-compensated ring core chokes with low stray inductance. Consider the B82721 series specifications regarding rated voltage (250 V AC) and current capabilities when designing switch-mode power supplies or electronic ballasts. Verify thermal performance and mounting constraints relative to the specific variant's physical dimensions and operating temperature range.

Part Context

This component belongs to the B82721 series of power line chokes manufactured by EPCOS, now part of TDK Electronics. These components are engineered as current-compensated ring core double chokes intended for suppressing common-mode interference in compact switch-mode power supplies and converters.
