11/07/2017 // Dennis M. Zogbi. This MarketEYE article describes the structure of the defense and aerospace electronics sector as an end-use market segment for electronic components such as capacitors, resistors and inductors. The market has been stagnant from 2012 to 2014 due to government imposed sequestering in the United States, but in 2015, 2016 and 2017 this market has shown signs of a substantial recovery driven largely through demand for commercial aircraft and space electronics.
Global Spending on Defense and Aerospace Electronics: 2005-2017
Revenues generated by the top global manufacturers of defense electronics between 2005 and 2012 were substantial, but they leveled off and then declined with the government imposed sequester in the United States until 2015, and then experienced an overall market increase in 2016 and stable environment in 2017.

Passive Component Consumption in Defense Electronics: 2012-2017
The passive component segment for defense electronics includes capacitors, resistors and inductors. Within those sub-categories, ceramic capacitors are the most preferred product line, followed by tantalum capacitors, although plastic film capacitors and aluminum electrolytic capacitors are also consumed in the defense and aerospace sector as well. IN resistors, the defense and aerospace segment consumes a myriad of ruthenium based chip resistors and networks, as well as nichrome metal film, tin-oxide and bulk metal foil resistor products; and wirewound resistors for power. In discrete inductors, consumption of molded chip and wirewound axial and radial leaded inductors is noted in defense and aerospace electronics. Capacitors are consumed for bypass, filtering and decoupling applications, but are also consumed in pulse discharge applications for radar circuits, munitions and railguns. Resistors are consumed in almost all defense platforms, and the segment prefers the use of nickel chromium in film, wire and foil formats because of its operational reliability and resistance to moisture. In discrete inductors for defense, the majority of products are consumed for noise abatement in communications and navigational equipment only.
Passive electronic component consumption value for applications in defense and aerospace electronics experienced a different pattern of consumption in electronic subassemblies in the sector since 2012. In fact, market data derived from the financial reports and statements of the key passive component vendors to the defense and aerospace sector- including such vendors as KEMET, AVX, and Vishay, who break out the defense and aerospace sector in a measureable way in their annual report and 10-K statement for each company respectively and we have determined that consumption of defense and aerospace capacitors, resistors and inductors declined from 2012 to 2016 and has only experienced a turnaround in 2017.
Fastest Growing Companies In Defense Electronic Sub-Assemblies & Platforms: 2012-2017
The world’s top manufacturers of commercial and defense aircraft drive demand for defense and aerospace electronics. Companies such as Raytheon and Rockwell Collins build products that are passive component intensive and are in turn consumed by other defense manufacturers such as The Boeing Company, Airbus and Lockheed Martin.
Boeing and Airbus are the largest manufacturers on the defense and aerospace manufacturers list and both companies account for about 39% of the defense electronics spend for the world for 2017 combined. Other major platform manufacturers such as Lockheed Martin, General Dynamics, BAE Systems, Northrop Grumman and Raytheon are also key customers for electronic components.
Customers in the sector that are showing the fastest growth rates for 2015, 2016 and 2017 include Lockheed Martin, BAE Systems, Northrop Grumman, Thales, L-3 Technologies, Rockwell Collins and Orbital Sciences Corp.

Summary and Conclusion
The defense and aerospace electronics sector represents a significant part of the value added and application specific segment of the passive electronic component supply chain. Because of its small size (i.e <$500 MM US Dollars in capacitor, resistor and inductor sales to defense worldwide), this segment of the market undergoes limited scrutiny and yet it requires capacitors, resistors and inductors that can operate at high temperature, high frequency and/or high voltage applications in multiple fragmented subassemblies primarily in avionics, communications, munitions and computing. This article attempts to shed light on the fragmented nature of this mission critical supply chain.
