Overview
The B82504WA3 is a common mode choke from the EPCOS B82504W series, designed for power line filtering. It features an I-core construction with a rectangular plastic case and resin potting. Key electrical parameters include an inductance of 2 mH and a rated current of 4 A. The DC resistance is 1.5 Ohms. It supports a rated voltage of 500 V AC or 600 V DC. The component utilizes chassis mounting via screw terminals. Operating temperature ranges from -40°C to +125°C. Dimensions are approximately 78.0 mm x 28.0 mm x 37.0 mm.
Feature Summary
- I-core choke design with rectangular plastic housing
- Resin potting for mechanical stability and environmental protection
- Chassis mount configuration with screw termination
- Dual-line common mode filtering capability
Applications
- Power line input filtering for electronic equipment
- EMI suppression in industrial control systems
- Noise reduction in AC/DC power supplies
Procurement Notes
Verify the specific suffix 'A3' against official EPCOS/TDK datasheets to confirm the 2mH/4A specification, as suffixes often denote distinct inductance or current ratings within the B82504W family. Confirm RoHS compliance status if required by your manufacturing standards. Ensure chassis mounting hardware compatibility with the specified screw terminal dimensions before procurement.
Selection Notes
Select this component when high current handling (4A) and moderate inductance (2mH) are required for common mode noise suppression. The chassis mount style is suitable for applications requiring robust mechanical fixation and heat dissipation. Verify that the 500V AC rating meets the system's voltage requirements. Consider the physical dimensions for enclosure space planning.
Part Context
The B82504W series comprises power line chokes manufactured by EPCOS, now part of the TDK Group. These components are engineered for robust performance in demanding environments. The series offers various inductance and current ratings, standardized by I-core construction. This specific model represents one variant within the broader family of power line filters designed for industrial and commercial applications.
Replacement Considerations
Consult official EPCOS/TDK substitution guides for direct replacements. Cross-reference inductance, current rating, and physical dimensions when evaluating alternatives. Ensure any substitute maintains the same mounting style and voltage rating.
