7103

Overview

The Bourns Inc. 7103 is a through-hole common mode choke designed for electromagnetic interference (EMI) filtering in two-line circuits. It provides a nominal inductance of 1.7 mH at 1 kHz and supports a current rating of 1 A with a DC resistance of 70 mOhm. The component effectively suppresses noise to ensure signal integrity.

Feature Summary

• Filters electromagnetic interference (EMI) to maintain clean signal matching between lines
• Suppresses noise for reliable operation in sensitive electronic designs

Applications

• General EMI filtering in electronic systems
• Noise suppression in two-line signal circuits

Procurement Notes

Verify the specific suffix code against official documentation, as variations may exist within the product line. Confirm that the required inductance and current ratings align with your circuit design before procurement. Ensure compliance with relevant environmental standards such as RoHS if applicable to your project requirements.

Selection Notes

Select this component when a through-hole solution is required for common mode noise reduction. Evaluate the 1.7 mH inductance and 1 A current capacity against your specific signal line requirements. Consider the physical dimensions and mounting style for compatibility with your printed circuit board layout constraints.

Part Context

This component belongs to Bourns' range of magnetic products, specifically common mode chokes used for circuit protection and signal integrity. These devices are engineered to attenuate unwanted high-frequency noise while allowing desired signals to pass, supporting various industrial and consumer applications.

Replacement Considerations

Consult official cross-reference data for verified substitutes. Ensure any replacement matches the 1.7 mH inductance, 1 A current rating, and through-hole package type to maintain circuit performance.
