Overview
The B82722A2252N001 is a current-compensated ring core double choke manufactured by EPCOS (TDK). It features a rated voltage of 250 V AC and a rated inductance of 2.5 mH. The component supports a maximum rated current of 3 A. Physical dimensions include a maximum length of 22.70 mm, width of 22.30 mm, and height of 13.30 mm. It utilizes through-hole mounting technology for integration into electronic circuits.
Feature Summary
- Current-compensated ring core design for effective common-mode noise suppression
- Rated for 250 V AC operation with high current handling capability
- Compact rectangular housing suitable for space-constrained applications
Applications
- Power line filtering in industrial equipment
- Electromagnetic compatibility (EMC) suppression in consumer electronics
- Input stage filtering in power supply units
Procurement Notes
Verify the specific suffix 'N001' against the manufacturer's latest datasheet to confirm compliance with RoHS directives and material composition requirements. Ensure that the rated current and voltage parameters align with the target circuit's operational limits before procurement. Cross-reference the ordering code with official TDK/EPCOS documentation to avoid counterfeit components.
Selection Notes
Select this component when designing circuits requiring common-mode chokes with a 2.5 mH inductance value. The 3 A current rating makes it suitable for moderate-power applications. Consider the physical footprint constraints as the maximum height is 13.30 mm. Ensure the operating environment temperature range is compatible with standard industrial specifications.
Part Context
This part belongs to the B82722 series of power line chokes from EPCOS (now TDK Electronics). The series offers various inductance values ranging from 1.2 mH to 68 mH within a standardized form factor. These components are widely used for EMC filtering in mains-powered devices across automotive, industrial, and consumer sectors.
Replacement Considerations
Compatible substitutes within the same series include B82722A2102N001 and B82722A2602N001, provided their respective inductance and current ratings meet the design requirements. Verify pinout and dimensional compatibility before substitution.
