B82721K2202N001

Overview

The B82721K2202N001 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a ferrite core and radial leads, designed for power line applications with a rated voltage of 250 V AC. The component has a nominal inductance of 1 mH per winding, a maximum DC current rating of 2 A, and a maximum DC resistance of 0.06 Ω. It operates within a temperature range of -40 °C to +125 °C and complies with RoHS standards.

Feature Summary

• Current-compensated design utilizing a ring core structure for effective common mode noise suppression
• Radial leaded construction suitable for through-hole mounting on printed circuit boards
• High thermal stability allowing operation up to +125 °C

Applications

• Power line filtering in electronic equipment
• Common mode interference suppression in AC mains circuits
• EMI reduction in general purpose power supplies

Procurement Notes

Verify the specific suffix N001 against official TDK documentation to confirm lead finish and packaging details. Ensure the selected variant matches the required 2 A current rating and 1 mH inductance specifications for your circuit design. Cross-reference the manufacturer part number with the latest datasheet to avoid discrepancies in electrical parameters or compliance status.

Selection Notes

Select this component when a high-current common mode choke is required for 250 V AC lines. The 2 A rating supports substantial load currents while maintaining low insertion loss. Consider the physical dimensions of 18.2 mm length and 20.3 mm height for board layout constraints. Verify that the radial lead pitch fits the target PCB footprint before finalizing the design.

Part Context

This component belongs to the B82721 series of power line chokes from EPCOS (TDK). The series offers various inductance values and current ratings tailored for different power line filtering needs. These chokes are widely used in industrial and consumer electronics to meet electromagnetic compatibility requirements.

Replacement Considerations

Consult the official B82721 series replacement guide for compatible alternatives. Ensure substitute parts match the 1 mH inductance, 2 A current rating, and 250 V AC voltage rating. Verify dimensional compatibility for through-hole mounting.
