157E

Overview

The Hammond Manufacturing 157E is a common mode choke belonging to the industrial-grade component series. It is designed for signal integrity and noise suppression in electronic circuits. The device features an unshielded construction, which allows for flexible mounting orientations without magnetic interference concerns from adjacent components. As a passive electromagnetic filter, it provides differential mode attenuation while maintaining high impedance to common mode noise currents. This component is suitable for applications requiring reliable filtering performance in controlled environments.

Feature Summary

• Common mode noise suppression capability
