B82721K2362N001

Overview

The B82721K2362N001 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It is designed for power line filtering applications with a rated voltage of 250 V AC. The component features an inductance of 0.4 mH and supports a maximum DC current of 3.6 A. Its maximum DC resistance is specified at 35 milliohms. The device utilizes a ferrite core material and employs radial termination for through-hole mounting. It operates within a temperature range of -40 °C to +125 °C and holds ENEC and UR approvals.

Feature Summary

• Current-compensated design effectively filters common mode noise on two lines while maintaining low impedance for differential signals.
• Constructed with a ring core ferrite structure to provide high efficiency in electromagnetic interference suppression.
• Supports through-hole vertical mounting with radial pins for secure integration into printed circuit boards.

Applications

• Power supply input filtering for electronic equipment
• Electromagnetic interference suppression in AC mains circuits
• Common mode noise reduction in industrial control systems

Procurement Notes

Verify the specific suffix N001 against official TDK documentation to confirm package dimensions and approval status. Ensure the selected variant matches the required 250 V AC rating and 3.6 A current capacity for the target application. Cross-reference the datasheet revision date to guarantee compliance with current safety standards and manufacturing specifications.

Selection Notes

Select this component when designing circuits requiring common mode chokes with high current handling capabilities up to 3.6 A. The low DC resistance minimizes power loss in the signal path. Consider the physical dimensions of 18.2 mm by 13.2 mm for board layout constraints. Verify thermal performance requirements against the specified operating temperature range of -40 °C to +125 °C.

Part Context

This part belongs to the B82721 series of current-compensated ring core double chokes from EPCOS. The series covers a wide range of inductance values and current ratings for power line applications. The K designation typically indicates specific mechanical or tolerance characteristics within the product family, distinguishing it from other variants like the A or J series.

Replacement Considerations

Consult official TDK substitution guides for direct equivalents. Verify that any alternative maintains the same 0.4 mH inductance, 3.6 A current rating, and 250 V AC voltage rating. Ensure mechanical compatibility regarding pin spacing and height for existing PCB footprints.
