Overview
The B82724J8103N040 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It features a common mode inductance of 500 µH and supports a maximum DC current of 10 A. The component has a low maximum DC resistance of 9 mOhms and operates within a temperature range of -40 °C to +125 °C. Rated for 250 V AC and 800 V DC, it utilizes a through-hole mounting style with a horizontal orientation.
Feature Summary
- Provides effective common mode noise suppression for power lines
- Current-compensated design minimizes magnetic field interference
- Robust construction suitable for high-current industrial applications
Applications
- Power line filtering in industrial machinery
- EMI suppression in AC/DC power supplies
- Noise reduction in automotive electronic systems
Procurement Notes
Verify the complete part number including the suffix N040 to ensure correct packaging and specifications. Confirm that the required operating temperature range aligns with the component's rated limits. Check datasheet details for mechanical dimensions to ensure compatibility with existing board layouts or chassis mounts. Ensure compliance with relevant safety standards for the intended application environment.
Selection Notes
Select this component when high current handling capability is required alongside significant common mode noise attenuation. The low DC resistance helps maintain efficiency in power delivery circuits. Consider the through-hole package type if surface mount options are not feasible for the specific assembly process or mechanical stress requirements.
Part Context
This component belongs to the B82724 series of current-compensated ring core chokes from EPCOS, now part of TDK Electronics. These components are designed for robust performance in demanding environments, offering reliable filtering solutions for power electronics where space and thermal management are critical factors.
Replacement Considerations
Consult official TDK/EPCOS documentation for direct cross-references. Verify inductance, current rating, and physical dimensions before substituting with similar parts from other manufacturers to ensure circuit compatibility.
