7107

Overview

The Bourns Inc. 7107 is a two-line common mode choke designed for through-hole mounting. It provides an inductance of 850 µH at 1 kHz and supports a maximum current rating of 2A. The component features a low DC resistance (DCR) of 40 mOhm, ensuring minimal power loss in signal lines. This magnetic filter is engineered to suppress electromagnetic interference (EMI) and radio frequency interference (RFI) in electronic circuits.

Feature Summary

• Provides effective common mode noise suppression for differential signal lines
• Utilizes through-hole construction for secure mechanical attachment
• Engineered with low DC resistance to maintain signal integrity

Applications

• Signal line filtering in industrial control systems
