B82722J2202N001

Overview

The B82722J2202N001 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a ferrite core and radial leads for through-hole mounting. The component has a nominal inductance of 2200 µH, a maximum DC resistance of 0.13 Ω, and a rated AC voltage of 250 V. It supports a maximum current of 2 A and operates within a temperature range of -40 °C to +125 °C. The physical dimensions are 23.3 mm in length, 16.1 mm in width, and 25.4 mm in height.

Feature Summary

• Current-compensated ring core design for effective common mode noise suppression
• Dual-element construction with four terminals for power line filtering
• Compliant with UL and ENEC (VDE) safety standards

Applications

• Power supply input filtering
• Battery charger circuits
• Portable device power stages
• Voltage regulation modules

Procurement Notes

Verify the specific suffix N001 against the manufacturer's latest datasheet to confirm lead type and compliance status. Ensure the selected variant matches the required 2200 µH inductance and 2 A current rating for the target application. Cross-reference safety approvals such as UL and ENEC if regulatory certification is mandatory for the end product.

Selection Notes

Select this component when high common mode rejection is required in compact power electronics. The radial leaded package facilitates automated insertion or manual assembly on standard PCBs. Consider the 25.4 mm height constraint during mechanical layout planning. The ferrite core material provides stable performance across the specified wide operating temperature range.

Part Context

This part belongs to the B82722 series of power line chokes designed for EMC mitigation in AC mains applications. The series offers various inductance values tailored for different current ratings. As a TDK/EPCOS product, it integrates into broader electromagnetic compatibility solutions for consumer and industrial electronic equipment.

Replacement Considerations

Check for direct substitutes within the B82722 series that match the 2200 µH inductance and 2 A rating. Verify dimensional compatibility before substitution. Ensure any alternative maintains equivalent UL and ENEC certifications for regulatory compliance.
