B82721J2262N001

Overview

The B82721J2262N001 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 400 µH and a rated DC current of 2.6 A. The component has a maximum DC resistance of 0.175 Ω and operates within a temperature range of -40 °C to +125 °C. It utilizes a through-hole mounting style with four terminals and measures 23.3 mm in length, 16.1 mm in width, and 25.4 mm in height.

Feature Summary

• Suppresses common-mode interference in switch-mode power supplies
• Current-compensated ring core design for balanced line filtering
• High thermal stability suitable for demanding environments

Applications

• Compact switch-mode power supplies
• Power converters of various types
• Industrial electronics equipment

Procurement Notes

Verify the specific suffix J against official datasheets to confirm tolerance and material specifications. Ensure the ordering code matches the required inductance and current ratings for your circuit design. Confirm RoHS compliance status as per the latest manufacturer documentation before finalizing procurement orders.

Selection Notes

Select this component when common-mode noise suppression is required in space-constrained power supply designs. The 2.6 A current rating and low DC resistance make it suitable for moderate power applications. Verify that the physical dimensions fit the available PCB real estate and that the operating temperature range meets system requirements.

Part Context

This part belongs to the B82721 series of current-compensated ring core chokes by EPCOS (TDK). These components are engineered for AC voltages up to 250 V and offer inductance values ranging from 0.2 to 39 mH with currents between 0.4 and 6.0 A. The series is widely used for EMI suppression in general-purpose power electronics.

Replacement Considerations

Check for direct substitutes within the B82721 series with matching inductance and current ratings. Cross-reference with other EPCOS power choke families if form factor constraints differ. Ensure any replacement maintains the same common-mode rejection characteristics and thermal performance.
