Overview
The B82506WA7 is a common mode choke from the EPCOS B82506W series, designed for power line filtering. It features an I-core construction with a rectangular plastic case and resin potting. The component has a rated voltage of 500 V AC / 600 V DC and supports a rated current up to 40 A. Key electrical parameters include an inductance of 200 µH and a maximum DC resistance of 0.01 Ω. It operates within a temperature range of -40 °C to +125 °C.
Feature Summary
- I-core choke construction with rectangular plastic housing
- Resin potting for mechanical stability and environmental protection
- High current handling capability suitable for power line applications
Applications
- Power line filtering in industrial equipment
- EMI suppression in high-current AC/DC power supplies

Procurement Notes
Verify the complete part number against official EPCOS/TDK documentation to ensure correct inductance and current ratings. Confirm RoHS compliance status and lead times through authorized distributors. Check for specific ordering suffixes that may affect packaging or terminal configuration. Ensure the procurement source provides valid traceability documents.
Selection Notes
Select this component when high current capacity and robust mechanical construction are required for common mode noise suppression. The 200 µH inductance and 40 A rating make it suitable for heavy-duty power applications. Consider the chassis mounting style and physical dimensions during PCB or panel layout design to ensure adequate clearance and thermal management.
Part Context
The B82506WA7 belongs to the B82506W series of power line chokes manufactured by EPCOS (TDK). This series is characterized by I-core technology and resin-potted rectangular cases, offering high reliability for demanding industrial environments. These components are engineered to meet stringent electromagnetic compatibility standards in power electronics systems.
Replacement Considerations
Cross-reference with other B82506W variants for different inductance values. Verify pinout and mounting hole patterns match existing designs. Consult official substitution lists for equivalent performance in terms of saturation current and impedance characteristics.
