Overview
The B82724B2132N020 is a current-compensated ring core double choke manufactured by TDK Electronics (EPCOS). It is designed for power line filtering applications with a rated voltage of 250 V AC. The component features an inductance of 2x13 mH and supports a maximum current of 1.3 A. It utilizes a D-core ferrite construction and is available in a through-hole horizontal package.
Feature Summary
- Current-compensated design for effective common mode noise suppression
- D-core ferrite construction for stable magnetic performance
- Horizontal mounting configuration for space-efficient PCB integration
Applications
- Power line filtering in electronic equipment
- Electromagnetic compatibility (EMC) circuits
- Industrial control systems
Procurement Notes
Verify the complete part number including suffixes to ensure correct packaging and tolerance specifications. Confirm that the 250 V AC rating and 1.3 A current capacity align with your circuit requirements. Check for RoHS compliance status if required by your manufacturing standards. Ensure the horizontal lead spacing matches your board layout constraints.
Selection Notes
Select this component when high inductance values are required for low-frequency noise attenuation in single-phase AC lines. The current-compensated nature makes it suitable for applications where differential mode interference is minimal compared to common mode noise. Consider the physical dimensions and mounting orientation during the mechanical design phase.
Part Context
This component belongs to the B82724 series of common mode chokes from EPCOS, now part of TDK Electronics. The series offers various inductance and current ratings tailored for different power line filtering needs. These components are widely used in consumer electronics, industrial machinery, and IT equipment to meet stringent EMC regulations.
Replacement Considerations
Consult official TDK/EPCOS documentation for direct cross-references. Verify that any substitute maintains the 2x13 mH inductance, 1.3 A current rating, and 250 V AC voltage rating. Ensure the replacement has compatible physical dimensions and mounting style.
