Spectrum Control, an established leader in EMI protection, introduces a dual line common mode panel mount EMI filter that reduces space and weight by 50% compared to two single line filters. The industry’s only dual line EMI filter that integrates a common mode choke in a 0.690-in. diameter package, it occupies less real estate on a power supply panel or chassis than alternative approaches and addresses emerging compact designs in military/aerospace, commercial, and industrial applications. 

The dual line common mode panel mount EMI filter combines a compact package with high performance to meet Size, Weight, Power and Cost (SWaP-C) requirements. Its innovative design employs a common mode choke and Line-Line capacitor to allow noise attenuation from both lines on inputs and outputs of AC or DC systems. It delivers reliable EMI filtering of common mode noise from 30 kHz to 1 GHz and differential mode noise from 30 kHz to 10 MHz. 

Designed to meet MIL-PRF-15733, the EMI filters have standard voltage ratings from 50 V to 200 VDC/130 VAC, 400 Hz. The experienced engineering team at Spectrum Control can also develop custom configurations.

Because of its high-performance and compact package, the dual line common mode panel mount EMI filter provides benefits in a wide range of power supply applications. It is well suited for commercial and military aerospace designs, including antenna arrays, radar, control systems, and navigation systems. The EMI filter can also be used in railway systems, analyzers, flow meters, test instruments, and other industrial applications.
