B82724A2272N020

Overview

The B82724A2272N020 is a current-compensated ring core double choke manufactured by EPCOS, now part of TDK Electronics. It belongs to the B82724A/J series and is designed for power line applications with a rated voltage of 250 V AC at 50/60 Hz. The component features an inductance of 1.8 mH and supports a maximum DC current of 6 A. It utilizes a horizontal through-hole mounting style with dimensions of 33.10 mm length, 32.50 mm width, and a maximum height of 19.70 mm. The device operates within a temperature range of -40°C to +125°C and includes a test voltage rating of 1500 V AC for 2 seconds between lines.

Feature Summary

• Current-compensated design utilizing a ring core structure for effective noise suppression
• Horizontal through-hole packaging suitable for robust power line integration
• High thermal stability supporting operation up to 125°C

Applications

• Power line filtering in industrial equipment
• Electromagnetic interference suppression in automotive systems
• Common mode choke applications in general electronics

Procurement Notes

Verify the specific ordering suffix N020 against official TDK documentation to ensure correct tolerance and packaging specifications. Confirm that the horizontal package dimensions align with your PCB layout constraints. Check for any recent brand transition notices from EPCOS to TDK regarding passive components to ensure supply chain continuity and accurate part identification during procurement.

Selection Notes

Select this component when a high-current capacity of 6 A is required alongside significant inductance for power line filtering. The horizontal form factor is advantageous for space-constrained boards where vertical clearance is limited but footprint area is available. Ensure the operating environment does not exceed the 125°C thermal limit and that the 250 V AC rating matches the system's electrical requirements.

Part Context

This component is part of the B82724A/J series of common mode chokes, which are widely used for electromagnetic compatibility (EMC) improvements. As a product of EPCOS, now integrated into TDK Electronics, it represents a standard solution for filtering noise on power lines in various electronic devices. The series is known for its reliability in both industrial and automotive environments.

Replacement Considerations

Consult official TDK documentation for direct substitutes within the B82724A/J series or equivalent current-compensated ring core chokes. Verify that any replacement maintains the 1.8 mH inductance, 6 A current rating, and 250 V AC voltage specification to ensure functional compatibility without redesigning the circuit.
