B82724J8482N040

Overview

The B82724J8482N040 is a current-compensated ring core double choke manufactured by EPCOS, part of the TDK Group. It features a vertical package with four PC pins and operates at a rated voltage of 250 V AC (50/60 Hz) or 800 V DC. The component withstands a test voltage of 2000 V AC for 2 seconds between lines. Designed for a rated temperature of +70 °C, it utilizes a ferrite core construction to provide effective electromagnetic interference suppression in power supply circuits.

Feature Summary

• Current-compensated ring core design for balanced noise suppression
• Vertical mounting configuration with four printed circuit board pins
• High dielectric strength with 2000 V AC line-to-line test voltage capability

Applications

• Electromagnetic interference suppression in power supply units
• Common mode noise filtering in industrial electronics
• Input stage filtering for equipment operating at 250 V AC

Procurement Notes

Verify the specific datasheet version for the B82724J8482N040 to confirm the exact rated current value, as this critical parameter varies within the series. Ensure the application environment does not exceed the +70 °C rated temperature limit. Confirm that the vertical pin spacing matches the target PCB footprint requirements before finalizing procurement.

Selection Notes

Select this component when high common mode rejection is required in a compact vertical form factor. The 800 V DC rating allows suitability for applications involving higher potential differences compared to standard low-voltage chokes. Consider the thermal constraints carefully, as the performance is limited to a maximum operating temperature of +70 °C.

Part Context

This component belongs to the B82724J series of current-compensated ring core double chokes from EPCOS. These components are engineered for robust electromagnetic compatibility in demanding environments. The series is widely utilized in industrial and consumer electronics to mitigate conducted disturbances on power lines.

Replacement Considerations

Check the B82724J8202N040 for alternative inductance values within the same series. Verify mechanical dimensions and pin configurations to ensure direct compatibility with existing PCB layouts without redesign.
