7119

Overview

The Bourns Inc. 7119 is a through-hole common mode choke designed for data line filtering applications. It features two lines and provides an inductance of 5 mH with a rated current capacity of 4 A DC. The component exhibits a maximum DC resistance of 0.046 Ω. It operates within a temperature range of -55°C to 105°C and measures 30.48 mm in length, 20.32 mm in width, and 30.48 mm in height.

Feature Summary

• Provides common mode noise suppression for data lines
• Supports high current operation up to 4 A
• Designed for through-hole mounting on printed circuit boards

Applications

• Data line filtering
• EMI suppression in electronic circuits

Procurement Notes

Verify RoHS compliance status carefully as sources indicate conflicting information regarding lead content. Confirm the specific inductance value (4.25 mH vs 5 mH) required for the application against the official datasheet. Ensure the through-hole package dimensions match the PCB layout constraints before ordering.

Selection Notes

Select this component when a 4 A current rating and approximately 5 mH inductance are required for common mode noise reduction. The through-hole construction suits applications where surface mount options are unsuitable. Verify thermal performance requirements against the -55°C to 105°C operating range.
