8114

Overview

The Bourns 8114 is a common mode choke belonging to the 8100 series, manufactured under the J.W. Miller trademark. It features a minimum inductance of 2.5 mH at 1 kHz and supports a current rating of 12.5 A with a DC resistance of 11 mOhm. The component utilizes a through-hole vertical package configuration with four terminals. This product is currently classified as obsolete or end-of-life.

Feature Summary

• Provides common mode noise suppression for dual-line circuits
• Vertical through-hole mounting configuration
• High current handling capability

Applications

• Power supply input filtering
• Industrial equipment EMI suppression
• Telecommunications line protection

Procurement Notes

This component is officially discontinued by the manufacturer. Availability is restricted to surplus stock only. Verify RoHS compliance status carefully, as legacy parts may not meet current environmental standards. Confirm terminal compatibility and physical dimensions before integration into new designs due to obsolescence.

Selection Notes

Engineers should evaluate alternative components from the same family or newer generations due to the discontinuation status. Ensure replacement parts match the required 2.5 mH inductance and 12.5 A current specifications. Verify that substitute chokes maintain similar physical footprint constraints for existing PCB layouts.

Part Context

Part of the Bourns 8100 series of common mode chokes. Manufactured under the J.W. Miller brand identity within the Bourns portfolio. Categorized under Inductors, Chokes & Coils. Designed for robust electromagnetic interference reduction in power and signal lines.

Replacement Considerations

Consult official Bourns documentation for direct cross-reference part numbers. Verify electrical equivalence including inductance tolerance and saturation current. Physical pinout compatibility must be confirmed for drop-in replacements.
