7104

Overview

The Bourns Inc. 7104 is a through-hole common mode choke designed for two-line applications. It features an inductance of 2.55 mH measured at 1 kHz and supports a current rating of 1 A. The component utilizes a core material optimized for common mode noise suppression with a DC resistance (DCR) of 100 mOhm. This device is intended for insertion into printed circuit boards to filter electromagnetic interference in signal or power lines.

Feature Summary

• Provides common mode noise attenuation for dual-line circuits
• Through-hole construction for standard PCB mounting
• Low DC resistance to minimize signal loss

Applications

• Signal line filtering
• Power supply EMI suppression
• General purpose noise reduction in electronic assemblies

Procurement Notes

Verify the specific suffix code against the manufacturer's official documentation to confirm exact electrical tolerances and packaging specifications. Ensure the selected variant matches the required current rating and inductance values for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component based on the requirement for a 2.55 mH inductance at 1 kHz and a 1 A current handling capability. Consider the through-hole package style and the low DCR specification when evaluating compatibility with existing board layouts and thermal management strategies.

Part Context

This component belongs to Bourns' portfolio of passive magnetic components, specifically within the common mode choke category. It serves as a fundamental element for maintaining signal integrity and reducing conducted emissions in various electronic systems requiring reliable noise filtration.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement part matches the 2.55 mH inductance, 1 A current rating, and through-hole form factor to maintain circuit performance.
