7116

Overview

The Bourns Inc. 7116 is a through-hole common mode choke designed for attenuating common mode noise in two-line configurations. It features an inductance of 6.8 mH measured at a test frequency of 1 kHz and supports a current rating of 2 A. The component has a maximum DC resistance of 200 mOhms and operates within a temperature range of -55 °C to +105 °C. With a lead pitch of 7.62 mm and a length of 20.32 mm, it provides reliable filtering for data cables and power supply applications.

Feature Summary

• Provides attenuation of common mode noise in two-line circuits
• Designed for use in data cable and power supply applications
• Through-hole construction with UL approval

Applications

• Data cable filtering
• Power supply noise suppression

Procurement Notes

Verify the specific suffix (e.g., RC) as it may indicate packaging or compliance variations not detailed in general specifications. Confirm availability status, as some listings indicate this model may be obsolete. Ensure the required inductance tolerance and current ratings align with the design requirements before ordering.

Selection Notes

Select this component when a 6.8 mH common mode choke is required for two-line signal or power paths. Consider the 2 A current rating and 200 mOhm DCR limits for circuit compatibility. Verify that the through-hole package and 7.62 mm lead pitch fit the PCB layout constraints.

Part Context

This component belongs to the Bourns common mode choke family, which offers various inductance values and current ratings for EMI suppression. The 7116 series is specifically engineered for applications requiring robust noise filtering in industrial and consumer electronics environments.

Replacement Considerations

Check for direct substitutes from Bourns or other manufacturers offering identical 6.8 mH inductance and 2 A current ratings. Ensure pin compatibility and physical dimensions match if space is constrained.
