B82724J2482N020

Overview

The B82724J2482N020 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It is designed for power line filtering applications with a rated voltage of 250 V AC at 50/60 Hz. The component features an inductance of 49 mH measured at 10 kHz and supports a maximum DC current of 2 A. It utilizes a ferrite core material and is housed in a horizontal through-hole package measuring 33.20 mm in height, 33.10 mm in length, and 32.50 mm in width. The device operates within a temperature range of -40 °C to +125 °C and undergoes a test voltage of 1500 V AC for 2 seconds between lines.

Feature Summary

• Provides common mode noise suppression for power lines using a current-compensated ring core design.
• Ensures stable operation in high-voltage environments with a 250 V AC rated voltage.
• Supports robust thermal performance across a wide operating temperature range.

Applications

• Power line filtering in industrial equipment
• Electromagnetic interference suppression in automotive electronics
• Noise reduction in consumer appliance power supplies

Procurement Notes

Verify the specific suffix N020 against official TDK datasheets to confirm pin configuration and tolerance. Ensure the required inductance value matches the application's frequency response needs. Confirm that the through-hole mounting dimensions fit the target PCB layout. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when high inductance values are required for effective low-frequency noise attenuation. The current-compensated design minimizes saturation effects under load. Consider the physical size constraints as the horizontal package occupies significant board area. Evaluate the thermal management requirements given the 125 °C maximum operating temperature limit.

Part Context

This part belongs to the B82724 series of power line chokes from EPCOS, now part of TDK Electronics. The series is characterized by its ring core construction and suitability for general-purpose power line filtering. These components are widely used in industries requiring reliable electromagnetic compatibility and stable power delivery.

Replacement Considerations

Consult official TDK documentation for direct substitutes within the B82724 family. Verify that alternative parts match the 49 mH inductance and 2 A current rating. Ensure mechanical compatibility with the existing through-hole footprint before substitution.
