As defense systems become more connected, powerful, and electronically complex, military OEMs face growing challenges related to power quality, EMI compliance, ruggedization, and cybersecurity. The ability to power and protect these systems has become just as critical as the systems themselves.
The defense electronics market continues to expand as governments invest in modernization programs across land, sea, air, and space domains.
Key military applications include:
With military electronics representing a substantial and growing global market, manufacturers must deliver solutions that meet strict reliability and compliance requirements while supporting increasing power demands.
Military systems operate in some of the harshest electromagnetic environments imaginable. Failure to control conducted and radiated emissions can impact mission-critical communications, navigation, surveillance, and weapon systems.
MIL-STD-461 establishes extensive emissions and susceptibility requirements for military equipment.
The standard includes testing such as:
Every subsystem connected to military power infrastructure must demonstrate compliance to ensure overall platform performance and survivability.
While MIL-STD-461 focuses on electromagnetic compatibility, TEMPEST requirements address information security.
TEMPEST standards are designed to prevent compromising electromagnetic emanations that could reveal classified information. Applications include:
Compliance often requires:
EMI filters serve as the first line of defense against conducted noise entering or leaving military equipment.
Proper filtering helps military systems comply with:
Military applications often require more than standard commercial filtering. Shipboard systems, airborne platforms, and secure communication equipment frequently demand specialized designs with unique leakage current, connector, and attenuation requirements.
Astrodyne TDI supports a broad portfolio of military and TEMPEST-qualified EMI filtering solutions.

Many military applications require modifications beyond commercial off-the-shelf (COTS) products.
Common customizations include:
These modifications allow OEMs to accelerate qualification while minimizing development risk.
Defense platforms demand power systems capable of surviving environments that would quickly destroy conventional commercial electronics.
Military power solutions must support:
In addition, modern defense systems are driving demand for:
Available solutions include:
Military OEMs require more than products—they need long-term engineering and manufacturing partners.
Key differentiators include:
As military platforms become more connected, autonomous, and power-hungry, the importance of reliable power conversion and EMI/EMC protection continues to grow.
Whether supporting radar systems, electronic warfare platforms, secure communications, or next-generation autonomous vehicles, defense OEMs require partners that understand military compliance, rugged design, and long-term program support.
By combining proven EMI filter technologies, rugged power supplies, military UPS systems, and custom engineering expertise, manufacturers can accelerate deployment, reduce qualification risk, and ensure mission success in the world's most demanding environments.
