TDK-EPC is presenting three new sample kits of ceramic PTC thermistors from EPCOS. The components of the sample kit “SMD PTC Thermistors for Limit Temperature Sensing/Superior Series” are designed for use as temperature sensors. The kit contains samples for sizes 0402, 0603 and 0805 across the temperature range between 75 and 145 °C in steps of 10 K. All thermistors are … [Read more...]
Sensor Film Monitors Surface Temperature Variations in Heat Sinks
Thermex® is a thin sensor film that can be used in multiple applications to test and monitor heated contacting surfaces from 200° to 300°F (93° to 149°C). Upon exposure to heat, Thermex® changes color instantaneously and permanently to reveal temperature distribution between any two contacting surfaces. Read more from Sensor Products. … [Read more...]
High-Accuracy 2.25 V Digital Temperature Sensor with Dual Alarm
STMicroelectronics has announced a super-small and power-efficient temperature sensor allowing portable devices to benefit from features such as intelligent thermal protection. ST’s new STTS751 Digital Temperature Sensor (DTS) is mounted on the circuit board to feedback accurate temperature data allowing the system to manage its temperature, for example, by activating a … [Read more...]
±0.5% Tolerance Chip NTC Thermistors
Murata Electronics North America added the ±0.5% tolerance option to its NCP series negative temperature coefficient (NTC) thermistor line. The ultra-tight tolerance thermistor is offered for consumer, industrial and automotive temperature ranges (-40°C to +150°C), and provides a low-cost alternative to integrated circuit (IC) based sensing solutions when high sensing accuracy … [Read more...]
Study: Carbon Nanotubes Could be Used for New Energy Systems
A team of scientists at Massachusetts Institute of Technology have discovered a previously unknown phenomenon that can cause powerful waves of energy to shoot through minuscule wires known as carbon nanotubes. The discovery could lead to a new way of producing electricity, the researchers say. The phenomenon, described as thermopower waves, is such a new discovery that it’s … [Read more...]
