Impacts of Space Radiation on Interconnect Wire Harnessing by Aerospace Wiring
Low Earth Orbits are increasingly being utilized by satellite networks geared for principal delivery of internet content on a worldwide basis. Low Earth Orbit, or LEO, happens to be relatively free from charged solar particles as it sits below the inner and outer Van Allen belts. Ionizing radiation remains an important factor however, and polar LEO orbits do cross charged particle areas at every pass. 

Space-Based Passive Electronic Components: Products, Markets, Competition and Outlook for 2022-2027 by Dennis Zogbi
Paumanok Industrial Market Research (IMR) estimates that the global core passive component spend for spacecraft and rockets is between $300 and $400 million worldwide for 2022. These include ceramic capacitors, tantalum capacitors, aluminum capacitors, plastic film capacitors; ruthenium, tantalum nitride, tin oxide and nickel chromium resistors; and ferrite cores, ferrite beads, ceramic chip coils and conical inductors.

Passives and the Privatization of Spaceflight by Murray Slovick
Private companies are doing a lot more in space today than they were ten years ago, including ferrying supplies to the International Space Station (ISS), landing and reusing rockets and creating constellations of small communications satellites. This commercialization of the space industry is taking the form of programs driven by a government agency for private (i.e. non-government) entities; low-cost missions (such as CubeSats); or the activities of private space companies focused primarily on the commercial aspects of space exploration.

Capacitors for Spacecraft: Withstanding a Harsh Radiation Environment by Murray Slovick
Dennis Zogbi’s terrific MarketEye column “Space-Based Passive Components: Global Market Update: 2016” prompted me to look into the effects of radiation on passives, and capacitors in particular, intended for use on spacecraft. Passives represent more than 80% of the electronic parts used on spacecraft, so radiation can be a major concern since space applications cannot afford to suffer a performance outage or loss of any function.

Solving High Performance Circuit Protection Needs in Space-constrained, High Density Electronics by Bourns
Bourns has employed a breakthrough flat package and horizontal circuitry design to innovatively meet the more sensitive overvoltage protection requirements of high density and space-restricted applications such as telecommunications and industrial communications equipment, surge protective devices and PCB assemblies.

How to Choose Connectors for Space by Harwin
There are many demanding applications on Earth, and many high-reliability connectors exist that will do a fine job performing in those environments. But space brings a few additional tricky problems, and a little extra planning is needed to make sure these are factored in to the connector choice.

What is Hi-Rel or High-Reliability for Connectors? by Harwin
Harwin high-reliability connectors are robust, able to withstand the utmost in environmental extremes, tested and inspected as the safest choice. High- reliability is the use of features, systems, or procedures to avoid failure in demanding circumstances or applications. In markets such as space, aviation, or defense, high-reliability is dictated when the task or equipment is mission-critical and involves risk to human life.

VITA 78 SpaceVPX Connectors White Paper by TE Connectivity
TE Connectivity's SpaceVPX is a standard for creating plug-in cards (PICs) from its slot profile and module (protocol) profiles. The primary goal of SpaceVPX is to be cost-effective when removing bandwidth as a constraint for future space systems. TE Connectivity connectors are extensively tested to establish suitability for space in satellite systems and other space applications.

Space-Grade Backshells for Micro-D and D-Sub Connectors by TE Connectivity
Select the right TE Connectivity space-grade backshell for applications utilizing D-Sub and Micro-D Connectors. Space-grade backshells seal out environmental irritants and ensure systems are properly grounded. The materials used in backshells for space-rated applications must be resistant to corrosion and able to withstand harsh environments.
