B82502WC2

Overview

The B82502WC2 is a common mode choke from the EPCOS B82502W series, designed for power line filtering. It features an I-core construction with through-hole mounting and four PC pins. The component has a rated voltage of 500 V AC / 600 V DC and a rated current range of 0.2 to 2 A. Specific variant B82502WC2 provides an inductance of 82 mH at a rated current of 200 mA. Dimensions are 1.969 inches L x 0.886 inches W (50.00 mm x 22.50 mm).

Feature Summary

• Broadband interference suppression for differential and common-mode signals.
• Low power dissipation design for efficient thermal management.
• Compact physical footprint suitable for space-constrained installations.

Applications

• Attenuation of differential and common-mode interference in electronic circuits.
• High-performance power supply input filtering.
• Industrial equipment power line noise reduction.

Procurement Notes

Verify the specific suffix code against official EPCOS/TDK documentation to confirm exact inductance and current ratings, as the base series covers a wide parameter range. Ensure the ordering part number matches the required 82 mH specification and 200 mA rating. Confirm package type and pin configuration align with PCB layout requirements before finalizing procurement orders.

Selection Notes

Select this component when broadband suppression is required for power lines operating up to 500 V AC. The 82 mH inductance value targets specific noise frequencies while maintaining a 200 mA current handling capability. Consider the through-hole mounting style and compact dimensions for integration into industrial or high-performance power supply designs where low power dissipation is critical.

Part Context

This component belongs to the EPCOS B82502W series of power line chokes utilizing I-core technology. The series offers various inductance values and current ratings to suit different filtering needs. EPCOS, now part of the TDK Group, manufactures these passive components for robust electromagnetic interference suppression in demanding electrical environments.

Replacement Considerations

Consult official cross-reference lists for verified substitutes within the B82502W series or equivalent I-core chokes from other manufacturers. Ensure replacement parts match the 82 mH inductance, 200 mA current rating, and 500 V AC voltage rating. Verify mechanical compatibility including pin spacing and housing dimensions before substitution.
