According to a survey by the German electronic component distributors’ association FBDi, sales in Germany fell by two percent in the sec- ond quarter of 2019, while European semiconductor dis- tribution market analyst DMASS reported a one percent Editorial decline in the same period. In both cases, however, trends in the individual elec- tronics sectors were quite inconsistent: sensor sales, for example, grew 22 percent in Germany. Among the losers were electromechanics and power supply, while Ingo Kuss, Editor-in- the large-volume semiconductor and passive component Chief product segments remained at the previous year’s level. of Markt& Across Europe, analog products and sensors achieved Technik growth, for example, whereas optoelectronics and LEDs performed worse. All in all, this does not yet represent grounds for panic, but it is a scenario in which the choice in favor of a par- ticular distributor is considered more carefully than it would be in times of unchecked growth.

The situation faced by distributors is no different. In this interview, Rutronik CEO Thomas Rudel talks about overall societal challenges and a tough twelve months for the industry, but nevertheless looks to the future with optimism.

At the same time, I believe that the CO2 debate and the way that it is focused solely on passenger cars is disingenuous: what about cruise ships, for example? And how will phas- ing out coal help us when we simultaneously subsidize coal-fired power plants elsewhere around the world? By confining the problem to “those evil passenger cars,” all we are do- ing is damaging our automotive industry – and putting jobs at risk in the process. But why shouldn’t Germany set a good example when it comes to protecting the Rutronik CEO climate? Thomas Rudel Naturally, Germany should lead the way as an innovative country. But CO2 is not the only problem, it is merely one of many problems. The priority for us is to see Pollution of the environment in general must a rapid resolution of the trade be addressed – collectively by all nations.
