B82724J2252N020

Overview

The B82724J2252N020 is a current-compensated ring core double choke from the EPCOS B82724A/J series. It features a horizontal mounting configuration with four pins for through-hole installation. The component provides an inductance of 10 mH at 10 kHz and supports a maximum current rating of 2.5 A. Its typical DC resistance is 140 mOhm, and it operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides common mode noise suppression for power lines using a current-compensated ring core design.
• Offers high inductance values suitable for filtering applications in AC power circuits.
• Constructed for robust performance across wide operating temperature ranges.

Applications

• Power line filtering in industrial equipment
• Noise suppression in consumer data processing units
• EMI reduction in AC power input stages

Procurement Notes

Verify the specific rated temperature class (TR) required for your application, as the B82724A/J series offers multiple thermal ratings including +40°C, +45°C, +50°C, +60°C, and +70°C. Ensure the selected variant meets the environmental conditions of the final assembly. Confirm that the horizontal package dimensions align with the PCB layout constraints.

Selection Notes

Select this component when a 10 mH inductance at 2.5 A is required for two-line power filtering. Consider the 140 mOhm DCR impact on voltage drop. Verify the test voltage requirement of 1500 V AC between lines against insulation standards. Compare physical dimensions against available board space for horizontal mounting.

Part Context

This part belongs to the B82724A/J series of power line chokes manufactured by EPCOS, now part of TDK Electronics. These components are designed for 250 V AC applications and utilize a current-compensated ring core structure. The series covers a broad range of inductances and current ratings for various power line filtering needs.

Replacement Considerations

Check for other variants within the B82724A/J series that may offer different thermal ratings or slight inductance tolerances. Ensure any substitute maintains the 10 mH nominal value and 2.5 A current handling capability while fitting the same horizontal footprint.
