Engineered for Harsh and Mission-Critical Environments
Ruggedized transformers and inductors for military and aerospace applications must operate in conditions where standard commercial components would fail. Standard hardware cannot withstand the extreme thermal cycling and physical stress found in flight systems. To prevent these failures, MPS Industries develops magnetic components for defense systems that endure:
- Extreme temperature ranges. Our components function reliably from -55 °C to +155 °C. This range allows them to maintain electrical performance even amid rapid temperature fluctuations in aerospace environments.
- High shock and vibration. We engineer components with reinforced construction to withstand sudden impacts and continuous vibration. Every design undergoes testing to MIL-STD-810 specifications to verify resistance to these environmental factors.
- Electromagnetic interference (EMI). Shielded designs and carefully selected core materials minimize susceptibility to EMI. These features also reduce radiated emissions that might otherwise interfere with sensitive avionics.
- Humidity and contamination. Hermetically sealed enclosures protect against moisture ingress and salt fog. This prevents moisture and other environmental contaminants from degrading performance over time.
Design Considerations for Defense Systems
Magnetic components for defense systems require balancing size, weight, and power (SWaP) constraints. Our team works with aerospace and defense OEMs to optimize:
- Power density. We achieve maximum power density within a minimal footprint. This reduces overall system weight, which is a vital factor for airborne and portable applications.
- Thermal management. Our custom winding configurations dissipate heat effectively. These designs work well in sealed enclosures where airflow is often limited.
- Reliability. Our engineering team eliminates single points of failure. We incorporate redundancies to support reliable operation throughout extended missions.
Military-Grade Magnetic Components
MPS Industries manufactures a diverse range of custom Mil-Spec magnetics. Each product undergoes comprehensive testing, including for thermal shock and electrical short circuits, to ensure it meets strict specifications before shipment. Our primary offerings include:
- Power transformers. These units provide power conversion for radar systems and electronic warfare equipment. In particular, our planar transformers provide high power density in a compact footprint while reducing skin effects.
- Current sense transformers. These precision components support motor control and fault detection. They are vital for weapons systems and vehicle electronics that require accurate current measurement.
- Military-grade inductors. We produce custom military-grade inductors for communication systems. These components operate from 10 kHz to several MHz, supporting high-frequency signal processing.
- Common mode chokes. These parts facilitate EMI suppression, meeting MIL-STD-461 requirements for conducted and radiated emissions while maintaining signal integrity.
Meeting MIL-STD and ISO 9001 Requirements
Our ISO 9001:2015-certified quality management system ensures consistent quality with every production run. As an ITAR-registered company, we maintain the documentation and test records required for government contractor sourcing. MPS Industries engineers military and aerospace magnetic components to meet several critical standards:
- MIL-STD-981: Construction standards for inductors, transformers, and other electromagnetic assemblies.
- MIL-STD-461: Requirements for electromagnetic interference control.
- MIL-STD-810: Environmental testing protocols for ruggedized transformers.
- MIL-PRF-27: Reliability specifications for power transformers and power inductors.
