B82724B2402N030

Overview

The B82724B2402N030 is a current-compensated ring core double choke manufactured by EPCOS, now part of TDK Electronics. It features a nominal inductance of 7 mH per line with a maximum rated current of 4 A. The component has a DC resistance of 1.1 Ohm and operates within a temperature range of -40°C to +125°C. Designed for horizontal through-hole mounting, it utilizes a ferrite core and is RoHS compliant.

Feature Summary

• Current-compensated design for effective common mode noise suppression
• Ring core construction for high inductance density
• Horizontal through-hole mounting configuration

Applications

• Power line filtering in electronic equipment
• Electromagnetic compatibility (EMC) improvement
• Common mode interference suppression in AC/DC power supplies

Procurement Notes

Verify the manufacturer designation as EPCOS or TDK Electronics on official documentation. Confirm the specific suffix N030 corresponds to the 7 mH / 4 A specification. Ensure compliance with RoHS directives if required for your assembly process. Cross-reference the datasheet for exact mechanical dimensions and thermal ratings before integration.

Selection Notes

Select this component when a 7 mH inductance at 4 A is required for common mode filtering. The horizontal package suits PCB layouts requiring low profile or specific pin spacing. Consider the 1.1 Ohm DC resistance for voltage drop calculations. Verify that the operating temperature range meets the environmental requirements of the target application.

Part Context

This component belongs to the B82724 series of power line chokes from EPCOS/TDK. These are designed for filtering electromagnetic interference in power lines. The series offers various inductance and current ratings to suit different power supply designs. EPCOS components are widely used in industrial, automotive, and consumer electronics for EMC compliance.

Replacement Considerations

Check for direct substitutes within the B82724 series with matching inductance and current ratings. Verify mechanical compatibility for through-hole mounting. Ensure electrical parameters such as DC resistance and saturation current meet or exceed original requirements.
