7113

Overview

The Bourns Inc. 7113 is a through-hole common mode choke designed for EMI suppression in electronic circuits. It features a maximum current rating of 2A and a DC resistance (DCR) of 75mOhm. The component operates within a temperature range of -55°C to 105°C. Its physical dimensions are 0.800 inches, providing a robust form factor for industrial applications requiring high impedance at low frequencies and dielectric strength of 3750 Vrms.

Feature Summary

• Reduces conductive EMI emissions
• High current capacity
• High impedance at low frequency

Applications

• Industrial circuit protection
• Power supply input filtering
• Data line noise suppression

Procurement Notes

Verify the specific suffix (e.g., RC) against the required packaging type, as bulk or tube options may exist. Confirm that the 2A current rating and 75mOhm DCR meet the design requirements. Ensure the operating temperature range of -55°C to 105°C is sufficient for the target environment. Check for AEC-Q200 compliance if automotive use is intended, though standard 7113 may not carry this certification.

Selection Notes

Select this component when high current handling and low DC resistance are critical for minimizing power loss in common mode noise reduction. The through-hole mounting style suits prototyping or high-reliability assemblies where mechanical stress resistance is prioritized over board space. Evaluate the 3750 Vrms dielectric strength for isolation requirements in mains-connected equipment.

Part Context

The 7113 belongs to Bourns' common mode choke lineup, focusing on electromagnetic interference suppression. Unlike resistor networks like the 4116R-1-361, this part is an inductive component. It complements Bourns' broader portfolio of signal conditioning and protection devices used in industrial and consumer electronics.
