Overview
The B82721J2202N001 is a current-compensated ring core power choke from the EPCOS B82721 series, designed for suppressing common-mode interference in compact switch-mode power supplies. It features a ferrite core with an inductance of 1 mH and a rated DC current of 2 A. The component has a typical DC resistance of 80 mOhm and operates within a temperature range of -40 °C to +125 °C. It utilizes a through-hole mounting style with four terminals.
Feature Summary
- Suppresses common-mode interference in switch-mode power supplies
- Current-compensated ring core design for balanced line filtering
- Suitable for compact converter applications
Applications
- Compact switch-mode power supplies
- Power converters
- Common-mode noise suppression circuits
Procurement Notes
Verify the specific suffix 'J' against official EPCOS/TDK documentation to confirm pinout orientation or tolerance specifications, as ordering suffixes may alter physical or electrical characteristics. Ensure the requested quantity matches distributor availability and that the component meets RoHS compliance requirements for your target market.
Selection Notes
Select this component when designing power lines requiring 1 mH inductance at 2 A DC current. Consider the 80 mOhm DC resistance for efficiency calculations. Verify that the through-hole package dimensions fit the PCB layout constraints and that the operating temperature range covers the application environment.
Part Context
This part belongs to the B82721 series of current-compensated ring core double chokes by EPCOS (TDK). These components are engineered for AC voltage ratings up to 250 V and offer inductance values ranging from 0.2 to 39 mH across the series, targeting general-purpose power line filtering needs.
Replacement Considerations
Check for direct substitutes within the B82721 series with matching inductance and current ratings. Verify equivalent parts from other manufacturers only if they meet the same 1 mH, 2 A, and through-hole form factor specifications documented for this series.
