Overview
The B82724J4402N1 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It features a ferrite core and radial leads, designed for power line applications. The component has a nominal inductance of 3.3 mH per winding with a maximum DC resistance of 40 milliohms. It supports a rated AC voltage of 250 V at 50/60 Hz and withstands a test voltage of 1500 V AC for two seconds. The device operates within a temperature range of -40 °C to +125 °C and carries RoHS compliance.
Feature Summary
- Current-compensated ring core design for efficient magnetic flux cancellation
- High thermal stability due to specialized encapsulation technology
- Radial leaded construction for through-hole PCB mounting
- RoHS compliant manufacturing process
Applications
- Common mode interference suppression in power lines
- Switching mode power supply input filtering
- DC-link applications in frequency converters
- High voltage circuit protection
Procurement Notes
Verify the specific suffix N1 against the official TDK ordering code list to confirm the exact inductance tolerance and packaging format. Ensure the selected variant matches the required rated temperature class (+40°C to +70°C) for the target application environment. Cross-reference the datasheet parameters for DC resistance and saturation current to validate compatibility with the system's electrical load requirements before finalizing procurement.
Selection Notes
Select this component when high common mode rejection is required in compact power line designs. The current-compensated architecture minimizes size while maintaining performance under varying load conditions. Consider the operating temperature range and encapsulation benefits for environments requiring enhanced thermal stability and pollution resistance compared to standard unencapsulated chokes.
Part Context
This part belongs to the B82724 series of power line chokes from EPCOS/TDK. The series utilizes current-compensated ring core technology to achieve high inductance values in a small footprint. These components are engineered for robust performance in demanding industrial and consumer electronics applications involving mains power filtering and noise suppression.
Replacement Considerations
Consult the official TDK replacement guide for direct equivalents within the B82724 family. Verify that substitute parts maintain identical inductance, current ratings, and physical dimensions to ensure board compatibility without redesign.
