Overview
The B82732R2222B030 is a current-compensated D-core double choke manufactured by EPCOS (TDK Electronics). It features a rated inductance of 3.3 mH and a maximum DC current rating of 2.2 A at +40 °C. The component has a maximum DC resistance of 0.11 Ω and operates within a temperature range of -40 °C to 125 °C. Designed for power line applications, it utilizes a vertical through-hole mounting configuration with a rectangular ferrite core construction.
Feature Summary
- Current-compensated design utilizing a D-core structure for effective common mode noise suppression
- Vertical through-hole mounting format suitable for PCB integration
- Robust thermal performance supporting operation up to 125 °C
Applications
- Power line filtering in industrial equipment
- EMI suppression in AC/DC power supplies
- Noise reduction in general-purpose electronic circuits
Procurement Notes
Verify the specific datasheet version when sourcing, as specifications may vary between revisions. Confirm that the 2.2 A current rating aligns with your system's thermal environment, as derating may be required above +40 °C. Ensure the vertical leaded package dimensions fit your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a high-current common mode choke with a compact D-core footprint is required. The 3.3 mH inductance value targets specific frequency attenuation needs. Consider the 0.11 Ω DC resistance impact on voltage drop if efficiency is critical. Verify compatibility with automated insertion processes due to the through-hole form factor.
Part Context
This part belongs to the B82732R series of power line chokes from EPCOS/TDK. The series offers various inductance and current ratings tailored for different power line filtering requirements. These components are widely used in global electronics manufacturing to meet electromagnetic compatibility standards.
Replacement Considerations
Check for direct substitutes within the B82732R series or other TDK D-core chokes with matching 3.3 mH inductance and 2.2 A current ratings. Ensure any replacement maintains the same vertical through-hole pinout and physical envelope to avoid PCB redesign.
