Overview
The B82722A2501N020 is a current-compensated ring core double choke from the EPCOS B82722 series. It features a horizontal package with four PC pins and operates at a rated voltage of 250 V AC. The component provides a rated inductance range of 1.2 to 68 mH with a rated current capacity between 0.3 A and 3 A. Designed as a general-purpose power inductor, it utilizes a ferrite core for effective electromagnetic interference suppression in AC power line applications.
Feature Summary
- Current-compensated ring core design for differential mode noise suppression
- Horizontal through-hole mounting configuration with four PC pins
- Ferrite core construction optimized for power line choke applications
Applications
- AC power line filtering
- Electromagnetic interference suppression in power supplies
- General purpose inductor circuits requiring current compensation
Procurement Notes
Verify the specific inductance value within the 1.2 to 68 mH range against project requirements, as this parameter varies across the B82722A2501N series. Confirm that the 250 V AC rated voltage and appropriate rated current meet the target circuit specifications. Ensure the horizontal package style with four PC pins aligns with the printed circuit board layout constraints.
Selection Notes
Select this component when current-compensated common-mode chokes are required for AC power lines up to 250 V. The B82722 series offers various inductance values; choose this specific suffix only if the associated electrical characteristics match the design needs. Consider the physical dimensions and lead spacing for PCB integration during the selection process.
Part Context
This part belongs to the B82722 series of power line chokes manufactured by EPCOS (TDK). The series comprises current-compensated ring core double chokes designed for suppressing electromagnetic interference in AC mains applications. These components are characterized by their robust ferrite core construction and standardized pin configurations suitable for through-hole mounting technologies.
Replacement Considerations
Consult official TDK/EPCOS documentation for verified substitute part numbers within the B82722 family or equivalent product lines. Cross-reference inductance, current rating, and voltage ratings before substitution.
