‘Thermal Conductivity’
An Electronicstalk guide
Start with the news release Self-protected MOSFETs for automotive applications from Diodes Incorporated, which we summarised at the time by saying "Suiting automotive and industrial applications, Diodes Incorporated's new self-protected MOSFETs are suitable for switching inductive loads, such as motors, relays and lamps at low frequencies. ". Several months prior to that, we featured the news release Compact linear regulator with thermal resistance from Linear Technology: "Linear Technology has produced a wider-temperature-range version of the LT3010, a high-voltage, micropower linear regulator for avionics, military, industrial, automotive, RF and telecom applications.".
In December 2010, we covered the news from Rogers - take a look at Rugged flame-retardent laminates for military PCBs which says: "Rogers has introduced XT/duroid high-performance thermoplastic laminate materials, suitable for high-frequency multilayer circuits in military, aerospace and deep-space applications.".
Take a look also at the news release from Allegro Microsystems, Sensor IC withstands harsh automotive environments, as well as Globtek offers desktop-style power supplies from Globtek, and HTC material for low loss in high-power circuits from Rogers.
