Overview
The B82720S2152N040 is a current-compensated ring core choke manufactured by EPCOS (TDK Electronics). It features a surface mount design with four terminals and an inductance of 1.6 mH at 10 kHz. The component has a typical DC resistance of 110 mOhm and supports a rated current of 1.5 A. It operates within a temperature range of -40°C to +125°C.
Feature Summary
- Current-compensated ring core construction for effective common mode noise suppression
- Surface mount packaging for automated assembly integration
- Four-terminal configuration supporting dual-line filtering applications
Applications
- Power line filtering in industrial electronics
- EMI suppression in AC/DC power supplies
- Noise reduction in computer peripheral interfaces
Procurement Notes
Verify the manufacturer designation, as the component is produced under both EPCOS and TDK Electronics branding. Confirm the specific suffix matches the required 1.6 mH inductance and 1.5 A current rating. Ensure the surface mount package dimensions align with the target PCB footprint before finalizing procurement orders.
Selection Notes
Select this component for applications requiring compact common mode chokes with high current handling capabilities. The 1.6 mH inductance provides effective attenuation for standard power line frequencies. Consider the 110 mOhm DC resistance for efficiency calculations in low-voltage circuits where voltage drop must be minimized.
Part Context
This part belongs to the B82720 series of current-compensated ring core chokes. These components are designed for power line applications, offering robust electromagnetic interference filtering. The series utilizes ferrite materials to achieve stable performance across varying environmental conditions and load currents.
Replacement Considerations
Check for direct substitutes within the B82720 series that share identical inductance and current ratings. Verify pin compatibility and mechanical dimensions when considering alternative manufacturers. Ensure any replacement maintains the same operating temperature range and RoHS compliance status.
