8111-RC

Overview

The Bourns 8111-RC is a two-line common mode choke designed for through-hole mounting. It features an inductance of 12 mH at a test frequency of 1 kHz and supports a maximum DC current of 4 A. The component has a maximum DC resistance of 110 mOhms and operates within a temperature range of -55 C to +105 C. Physical dimensions include a length of 1.35 inches, width of 0.80 inches, and height of 0.90 inches, with a lead spacing of 0.60 inches.

Feature Summary

• Provides electromagnetic interference suppression for sensitive components
• Designed for vertical through-hole installation
• Unshielded construction for standard filtering applications

Applications

• LED driver circuits
• Power supply input filtering
• Industrial control systems

Procurement Notes

Verify the specific suffix RC against the manufacturer's latest documentation to confirm compliance status and packaging details. Ensure the selected variant matches the required thermal and electrical ratings for the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a 12 mH inductance and 4 A current rating are required for common mode noise reduction. Verify that the physical footprint and lead spacing fit the PCB layout constraints. Confirm that the unshielded design does not interfere with nearby magnetic-sensitive components in the assembly.

Part Context

This part belongs to the Bourns 8100 series of common mode chokes. These components are engineered for general-purpose EMI filtering in various electronic markets including consumer electronics, industrial equipment, and telecommunications infrastructure.

Replacement Considerations

Check for direct substitutes within the same series or comparable inductance and current ratings from other manufacturers if availability is limited.
