Overview
The B82724B2102N001 is a current-compensated ring core double choke manufactured by EPCOS, now part of TDK Electronics. It features a rated inductance of 33 mH with a tolerance of 30%. The component supports a maximum DC current of 1 A and exhibits a maximum DC resistance of 750 mOhms. Designed for through-hole mounting, it operates within a temperature range of -40°C to 125°C. This common mode choke is classified as an electronic filter component suitable for power line applications.
Feature Summary
- Current-compensated ring core construction for effective noise suppression
- Dual-line configuration supporting common mode interference reduction
- Through-hole mounting design for robust mechanical integration
Applications
- Power line filtering
- Common mode choke applications
- Electronic filter circuits
Procurement Notes
Verify the manufacturer designation carefully, as EPCOS components are now branded under TDK Electronics following corporate restructuring. Confirm that the specific suffix N001 corresponds to the required lead-free and RoHS compliant version. Ensure the 33 mH inductance rating aligns with your circuit's noise suppression requirements before procurement.
Selection Notes
Select this component when a high inductance value of 33 mH is required for common mode noise attenuation in power lines. The 1 A current rating makes it suitable for moderate power applications. Consider the through-hole package if PCB space allows and higher mechanical stability is needed compared to surface mount alternatives.
Part Context
This component belongs to the B82724 series of power line chokes from EPCOS/TDK. These devices utilize current-compensated ring core technology to provide differential mode immunity while suppressing common mode signals. The series offers various inductance values tailored for different power line filtering needs across industrial and consumer electronics.
Replacement Considerations
Check for direct substitutes within the B82724 series offering similar 33 mH inductance and 1 A current ratings. Verify pin compatibility and physical dimensions to ensure interchangeability without PCB redesign.
