Overview
The B82721K0152N002 is a current-compensated ring core double choke manufactured by EPCOS (TDK Electronics). It belongs to the B82721 series of power line chokes designed for electromagnetic compatibility applications. The component features a radial termination style and utilizes ferrite core material. Key electrical specifications include an inductance of 1 mH, a maximum DC current rating of 1.5 A, and a rated voltage of 250 V AC. The device operates within a temperature range of -40°C to +125°C.
Feature Summary
- Current-compensated ring core construction for effective common mode noise suppression
- Ferrite core material providing stable magnetic properties across operating temperatures
- Radial through-hole mounting configuration suitable for standard PCB assembly
Applications
- Power line filtering in electronic equipment
- Electromagnetic compatibility (EMC) suppression circuits
- Common mode interference reduction in AC power inputs
Procurement Notes
Verify the complete part number including the suffix N002 to ensure correct packaging and tolerance specifications. Confirm that the 1.5 A current rating and 1 mH inductance align with the specific circuit requirements. Check for RoHS compliance status as indicated in official datasheets before finalizing procurement orders.
Selection Notes
Select this component when designing circuits requiring common mode chokes with a 1 mH inductance and 1.5 A current handling capability. Ensure the radial package fits the available PCB space and that the operating temperature range meets environmental conditions. Compare against other B82721 variants if different inductance or current values are needed.
Part Context
This component is part of the B82721 series of power line chokes from EPCOS (TDK Electronics). The series offers various inductance and current ratings tailored for EMC applications. These chokes are widely used in industrial, automotive, and consumer electronics to mitigate electromagnetic interference on power lines.
Replacement Considerations
Consult official TDK/EPCOS documentation for direct substitutes within the B82721 series. Verify equivalent inductance, current rating, and physical dimensions before considering alternative manufacturers.
