B82724J8612N040

Overview

The B82724J8612N040 is a current-compensated ring core double choke manufactured by EPCOS, now part of TDK Electronics. Designed for power line filtering, this component features a common mode inductance of 1.5 mH and supports a rated current of 6.1 A. It utilizes a through-hole mounting configuration suitable for horizontal installation. The device operates within a temperature range of -40°C to +125°C and withstands a test voltage of 2000 V AC between lines for two seconds. Rated for 250 V AC at 50/60 Hz or 800 V DC, it provides robust electromagnetic interference suppression for electronic circuits requiring reliable noise reduction.

Feature Summary

• Current-compensated design ensures minimal differential mode impedance while maintaining high common mode rejection.
• Ring core construction provides stable magnetic properties and compact form factor for efficient circuit board integration.
• High insulation capability with verified test voltage rating ensures safety in high-voltage power applications.

Applications

• Power supply input filtering for industrial equipment
• Electromagnetic interference suppression in consumer electronics
• Noise reduction in automotive electronic control units

Procurement Notes

Verify the specific ordering suffix against the official EPCOS/TDK datasheet to confirm mechanical dimensions and pinout compatibility. Ensure that the requested quantity aligns with standard packaging formats defined by the manufacturer. Confirm that the component meets the required environmental certifications for the target application region. Cross-reference the manufacturing date code if long-term availability is critical for the production schedule.

Selection Notes

Select this component when high current handling up to 6.1 A is required alongside significant common mode noise attenuation. The 1.5 mH inductance value is suitable for lower frequency interference suppression compared to higher inductance variants. Consider the through-hole package constraints regarding PCB layout space and thermal management requirements during the initial design phase.

Part Context

This component belongs to the B82724 series of current-compensated ring core double chokes. The series is engineered for general-purpose power line filtering across various electronic industries. EPCOS, acquired by TDK Electronics, maintains this product line to support global demand for reliable passive components in power conversion and signal integrity applications.

Replacement Considerations

Consult the official EPCOS/TDK replacement guide for direct equivalents within the B82724 family. Verify that any substitute part matches the 1.5 mH inductance, 6.1 A current rating, and 250 V AC voltage specifications. Mechanical footprint compatibility must be confirmed before substitution to ensure proper mounting on existing printed circuit boards.
