Overview
The B82724A2222N020 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It features a ferrite core and radial leaded construction designed for power line applications. The component has a nominal inductance of 15 mH per winding, rated for a maximum DC current of 2.2 A. It operates within a temperature range of -40 °C to +125 °C and withstands a test voltage of 1500 V AC between lines.
Feature Summary
- Current-compensated ring core design for effective common mode noise suppression
- Radial leaded through-hole mounting for robust mechanical integration
- High insulation strength with 1500 V AC line-to-line test voltage capability
Applications
- Power line filtering in industrial equipment
- EMI suppression in AC power input stages
- Common mode noise reduction in general purpose electronic circuits
Procurement Notes
Verify the specific suffix N020 against the latest TDK product availability lists, as brand transitions may affect part numbering conventions. Confirm that the 15 mH inductance and 2.2 A current rating align with the target circuit requirements before finalizing procurement orders.
Selection Notes
Select this component when high common mode attenuation is required in space-constrained through-hole designs. Ensure the operating environment stays within the specified -40 °C to +125 °C range. Verify that the 2.2 A saturation current meets the peak load demands of the application without causing excessive inductance drop.
Part Context
This component belongs to the B82724A/J series of power line chokes from EPCOS, now integrated into TDK Electronics' passive component portfolio. The series utilizes current-compensated ring core technology to minimize electromagnetic interference while maintaining low differential mode impedance.
Replacement Considerations
Check for direct equivalents within the B82724A series with matching inductance and current ratings. Consider TDK-branded replacements if EPCOS branding is no longer supported in the supply chain.
