Overview
The B82724A2402N020 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a ferrite core and radial through-hole mounting. Key electrical parameters include an inductance of 4.7 mH, a rated AC voltage of 250 V, and a maximum DC current of 4 A. The component has a maximum DC resistance of 16 mΩ and operates within a temperature range of -40 °C to +125 °C. It is RoHS compliant and designed for power line filtering applications.
Feature Summary
- Current-compensated design for effective common-mode noise suppression
- Ferrite ring core construction for high saturation performance
- Radial leaded package suitable for through-hole PCB mounting
Applications
- Power line chokes for AC mains filtering
- Common mode noise suppression in electronic equipment
- EMI filtering in industrial control systems
Procurement Notes
Verify the specific suffix N020 against the manufacturer's datasheet to confirm terminal configuration and packaging details. Ensure the selected variant matches the required current rating and inductance tolerance for the target circuit. Cross-reference the part number with official TDK/EPCOS documentation to avoid counterfeit components.
Selection Notes
Select this component when a compact, high-current power line choke is required for 250 V AC applications. The 4.7 mH inductance provides significant impedance for common-mode interference. Consider the physical dimensions and thermal characteristics relative to the enclosure space and ambient operating conditions.
Part Context
This component belongs to the B82724 series of current-compensated ring core double chokes. The series offers various inductance values and current ratings tailored for different power line filtering needs. These chokes are widely used in consumer electronics and industrial machinery to meet electromagnetic compatibility standards.
Replacement Considerations
Compatible substitutes include other B82724 series variants from TDK/EPCOS with matching inductance and current ratings. Verify pinout compatibility and mechanical dimensions before substitution.
