The Impact of Military EMI Filters on Military Operations

Military electromagnetic interference (EMI) filters are crucial in aerospace and military applications. These specialized electronic components ensure all equipment adheres to strict emission requirements, filtering out electrical interference or noise that could disrupt the functionality of critical electronic systems. Keep reading to learn about the impact of military EMI filters on military operations, including their applications and performance capabilities.

Military Uses for EMI Filters 

Military operations use EMI filters for several key reasons, from protecting signal integrity to shielding devices in various operating environments.

Keeping Communication Channels Open

EMI shielding helps keep communication lines open and secure in military operations. Higher frequencies are common in today’s military devices, leading to an increased opportunity for interference. EMI shielding tackles this challenge by keeping military networks isolated from other civilian and foreign military networks. Keeping the networks apart protects the integrity of the signal while eliminating unwanted recipients from the communications.

EMI filters allow military personnel to trust incoming intel, speeding up the communication process by removing jammed signals to prevent enemies from leveraging confidential information.

Maintain Proper Functioning of Complex Electronics

EMI shielding maintains functionality of military devices outside of the typical communicative uses. While large vehicles and tanks may seem indestructible, EMI can at times disrupt internal components, impeding overall functionality. Drones and other smaller devices are also susceptible to EMI interference.

In addition to interfering with the performance of military vehicles and sensitive systems, EMI has the potential to negatively impact large-scale power grids in industrial setting. It is vital to create a barrier for both the input and output power using EMI Filtering to meet the demands of military usage. This type of EMI shielding can help prevent malfunction and miscommunication, protecting soldiers and civilians alike.

Captor Corporation EMI Filters for Military Use

Captor Corporation manufactures several types of COTS MIL-STD-461 EMI filtering solutions to withstand extreme environments frequently seen in military applications. These can mitigate conducted emissions ranging between 10 KHz and 10 MHz while staying at or below the maximum capacitance for 50Hz – 400Hz input power frequencies to meet various demands.:

• Single-phase EMI filters. Our new line of COTS EMI filters is specifically engineered for use with single-phase power lines in AC and DC applications. They can alleviate conducted emissions in line with MIL-STD-461 CE102 standards, industry standards, and key electrical requirements.
• Three-phase Wye EMI filters. Our three-phase Wye EMI filters are designed to mitigate conducted emissions in accordance with MIL-STD-461 CE102 standards, making them suitable for a range of ground, air, and sea applications. These filter assemblies integrate line-to-ground feed-through capacitors, with additional shielding effectively isolating the output and input compartments.
• Three-phase Delta EMI filters. Captor Corporation offers three-phase EMI filters for use with Delta 120/208 VAC power lines, mitigating conducted emissions in alignment with MIL-STD-461 CE102 requirements. For 254/440 VAC power lines, we recommend COTS MIL-STD-461 three-phase Delta EMI filters.

Specific design configurations are available depending on the application and filter type. Our custom EMI filters can include various components like metal oxide varistors and circuit breakers, along with military connectors for input/output connections when requested.
