8119-RC

Overview

The Bourns 8119-RC is a dual common mode choke designed for through-hole mounting. It features a single-layer wound construction with an optional header and mounting base. The component provides an inductance of 4 mH at 1 kHz and supports a maximum DC current of 14.5 A. Its DC resistance is 12 mOhms, ensuring low power loss. The unit operates within a temperature range of -55°C to +105°C and offers a dielectric strength of 1500 Vrms.

Feature Summary

• Dual line configuration for effective electromagnetic interference suppression
• Single-layer wound design with integrated mounting base
• High current handling capability suitable for demanding applications

Applications

• LED driver circuits
• Current control systems
• Surge protection against electrostatic discharge

Procurement Notes

Verify the specific RoHS compliance status (RoHS3) and confirm the inclusion of the optional header if required by your assembly process. Ensure the through-hole footprint matches your PCB layout constraints. Cross-reference the 14.5A current rating and 12 mOhm DCR with your circuit requirements to guarantee adequate performance margins under thermal conditions.

Selection Notes

Select this component when high current capacity and robust EMI filtering are required in a through-hole format. The 4 mH inductance value is suitable for standard line filtering applications. Consider the physical dimensions and the availability of the optional header for secure mounting. Verify that the operating temperature range meets the environmental demands of the final product.
