Only tantalum capacitors with established reliability are recommended for the space application. Commercial parts can vary materials and processes, increasing risk of failure in space application.
New Space is a business that has come pushing hard on the past years. With the development of mega-constellations as Iridium or OneWeb and the entrance of new companies from industry on Space business related to telecommunications, a relaxation on the classical requirements for space parts has come to this market.
New space missions include more extreme requirements of storage, operational temperatures, and vacuum conditions, and all this testing can be done in our laboratories at Alter Technology.
Two microcontrollers for space, the ATSAMV71Q21RT from Microchip Technology Nantes (formerly Atmel) and the UT32M0R500 from Cobham Microelectronic Solutions (formerly Aeroflex), are compared in this post
