B82504WA2

Overview

The B82504WA2 is a power line choke from the EPCOS B82504W series, designed for chassis mounting. It features an I-core construction with a rectangular plastic case and resin potting. The component provides common mode filtering for two lines in power applications. Key electrical parameters include an inductance of 7.5 mH and a rated current of 2 A. The DC resistance is specified at 0.1 Ohm. It operates within a temperature range of -40°C to +125°C and supports rated voltages of 500 V AC or 600 V DC.

Feature Summary

• I-core choke construction with rectangular plastic housing
• Resin potting for mechanical stability and environmental protection
• Chassis mounting design for secure installation
• Common mode filtering capability for dual-line power circuits

Applications

• Power line noise suppression in industrial equipment
• EMI filtering for AC/DC power supplies
• Electromagnetic compatibility enhancement in automotive electronics
• Signal integrity improvement in communication infrastructure

Procurement Notes

Verify the specific suffix 'A2' against official TDK-EPCOS documentation to confirm the exact inductance value of 7.5 mH and current rating of 2 A. Ensure the chassis mounting style matches the enclosure design. Confirm RoHS compliance status if required by the target application regulations. Cross-reference the datasheet revision date to ensure parameter accuracy.

Selection Notes

Select this component when high common mode attenuation is required for 500 V AC systems. The 7.5 mH inductance offers effective filtering for lower frequency interference compared to smaller values. The 2 A current rating suits moderate power applications. Consider the chassis mount form factor for space-constrained enclosures requiring robust mechanical fixation.

Part Context

This part belongs to the B82504W series of I-core chokes manufactured by EPCOS, now part of TDK Electronics. The series covers various inductance and current ratings for power line filtering. These components are engineered for reliability in demanding environments, utilizing ferrite cores and resin potting to withstand thermal and mechanical stress during operation.

Replacement Considerations

Check for direct substitutes within the B82504W series with matching 7.5 mH inductance and 2 A rating. Verify that alternative parts maintain the same chassis mounting dimensions and terminal configuration. Ensure equivalent voltage ratings and temperature performance characteristics before substitution.
