	Resistor Stability Put to the Test (Demo Video) In this video, our host Richard Zuratt puts the stability of the three major resistor technologies — foil, thin, and thick film — to the test. Each resistor type is subjected to an overload pulse and its change in resistance value is recorded. Due to the homogeneous nature of the VPG Bulk Metal® Foil resistor, it is the only of the three to experience no change from the high power pulse. This demonstrated performance makes foil resistors the technology of choice for critical applications where long-term stability and survivability are paramount.

NTC Thermistor Overview in 60 Seconds In this overview of NTC thermistors, Ametherm look at the different kinds and application uses for temperature sensing and how NTC thermistors accurately measure and compensate for temperature. This video will start by looking at the different types of NTC thermistors, such as probe assembly thermistors, disc and chip thermistors, and customizable thermistors. The different thermistor attributes will be examined, including voltage/current and resistance versus temperature.
