A common mode choke is an electrical filter that blocks high frequency noise common to two or more data or power lines while allowing the desired DC or low-frequency signal to pass.
While the trend of increasing semiconductor content has been evident for the past 30 years, the big jump in 2017 and 2018 was primarily due to the huge surge in DRAM and NAND flash
Space standards (such as ESCC and MIL standards) have helped throughout the years to develop the industry and to achieve de mission goals. Standards improve the competitiveness, efficiency and knowledge transfer within space business. However, standards are not frozen documents, but rather they must change and adapt to the current requirements of the industry and the new developments and knowledge gathered during all the years of space missions.
Knowing the relative strengths of electrolytic and film capacitors for power-conversion applications can help designers make the right choices for optimum overall size, weight, and BOM cost
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
