B82722A2202N002

Overview

The B82722A2202N002 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a rated voltage of 250 V AC and a rated inductance of 3.3 mH per line. The component supports a rated current of 2 A and operates within a temperature range of -40 °C to +125 °C. It utilizes a ferrite core with a cylindrical package and offers high insulation strength, verified by a test voltage of 1500 V AC for 2 seconds between lines.

Feature Summary

• Current-compensated design for effective common-mode noise suppression
• High thermal stability suitable for demanding environments
• Robust insulation performance for safety compliance

Applications

• Power line filtering in electronic equipment
• EMI suppression in AC power inputs
• Industrial control systems requiring robust chokes

Procurement Notes

Verify the specific rated temperature variant (+40 °C or +60 °C) required for your application, as this affects the maximum operating current. Confirm that the 250 V AC rating aligns with your local mains voltage standards. Ensure mechanical fitment checks are performed against the cylindrical package dimensions before integration into the final assembly.

Selection Notes

Select this component when a dual-line choke with current compensation is needed for 250 V AC applications. The 3.3 mH inductance provides significant impedance to common-mode interference. Consider the 2 A current rating to ensure it exceeds the peak load current of the circuit. The wide temperature range allows for use in both cold and hot operational environments without derating issues.

Part Context

This part belongs to the B82722A/J series of power line chokes from EPCOS. These components are designed for general-purpose EMI filtering in AC power circuits. The series is known for its compact cylindrical construction and reliable performance in industrial and consumer electronics. TDK Electronics continues to produce these under the EPCOS brand legacy.

Replacement Considerations

Direct substitutes include other B82722A series variants with matching 3.3 mH inductance and 2 A current ratings. Verify pinout compatibility and physical dimensions when considering alternative manufacturers. Ensure any replacement meets the same 1500 V AC insulation test requirements.
