‘Resistance Measurement’
An Electronicstalk guide
Start with the news release Outdoor cooler uses bi-polar thermostatic control from Laird Technologies, which we summarised at the time by saying "Laird Technologies has announced the release of its outdoor thermoelectric cooler series with bi-polar thermostatic control. ". Several months prior to that, we featured the news release Monitoring system features Nordic transceivers from Nordic Semiconductor: "Nordic Semiconductor has announced that Spantec has developed a fully comprehensive ANT+ telemedical remote monitoring system using Nordic nRF24AP2 eight-channel 2.4GHz ANT transceivers.".
In December 2010, we covered the news from International Rectifier - take a look at International Rectifier offers automotive MOSFETs which says: "International Rectifier has expanded its offering of 40 to 100V automotive-qualified MOSFETs, including a range of logic level devices. ".
Take a look also at the news release from RDP Electronics, Transducers suited to shock and vibration tests, as well as Compact linear regulator with thermal resistance from Linear Technology, and System host board for energy and medical sectors from Kontron.
