Thermistors, thermocouples, and RTDs for thermal management

August 31, 2021 By Jeff Shepard

Thermal management is the ability to control the thermal environment of an electronic system. It is often associated with cooling heat-generating electronics, but it also encompasses generating heat in cold environments to maintain optimal system operation or power wax-based linear motors. As a result of the many uses for thermal management, a wide variety of […]

Fuses, eFuses, thermistors, and fusible resistors — which and when?

August 25, 2021 By Jeff Shepard

Fuses, eFuses, various types of thermistors, and fusible resistors can provide varying levels of circuit protection. Fuses offer only the most basic level of overcurrent and short-circuit protection. Thermistors can be added to provide inrush current control, and a fusible resistor can provide both inrush current control and overcurrent/short-circuit protection. The most comprehensive protection is […]

NTC thermistors sport long-stability for e-mobility temperature sensing apps

June 23, 2020 By Aimee Kalnoskas

B58703M1103A NTC thermistors

TDK Corporation presents the new B58703M1103A temperature sensor − specifically developed for demanding e-mobility applications, which call for significant long-term stability. The NTC sensor is designed for a temperature range of -40°C to +150°C, whereby a temporary load of up to 200°C is permitted. At 25°C, the rated resistance is 10 kΩ with a B25/100 […]

Super-small PTC thermistors target over-current protection tasks in consumer electronics

February 18, 2020 By Aimee Kalnoskas

PTC thermistor

Murata Manufacturing has succeeded in commercializing the world’s smallest PTC thermistor (commonly known as a resettable fuse) in the 0201-inch size (0.6×0.3×0.3mm) for mobile devices, and has recently begun mass production of this device under the part number PRG03BC181QB6RL. As smartphones and mobile devices become increasingly multifunctional and more compact, demand is growing for smaller […]

Tiny linear thermistors offer 50% higher accuracy, high sensitivity, single-point calibration

February 18, 2020 By Aimee Kalnoskas

thermistors

Texas Instruments expanded its temperature sensing portfolio to include linear thermistors that deliver up to 50% higher accuracy than negative temperature coefficient (NTC) thermistors. The higher accuracy of TI’s thermistors enables operation closer to the thermal limits of the other components and the overall system, helping engineers maximize performance while reducing bill-of-materials (BOM) and total […]

Worst-case error analysis and calibration in temperature sensing systems using NTC and PTC thermistors

October 22, 2019 By Aimee Kalnoskas

NTC and PTC thermistors

by Hadi Ebrahimi-Darkhaneh, Texas Instruments For applications that employ temperature monitoring systems, measurement accuracy is a prime concern. Temperature sensors are affected by a variety of factors, including environmental conditions, manufacturing process variations, poor assembly, and nonideal biasing components. External components connected to temperature sensors (such as the power supply, an analog-to-digital converter [ADC] and […]

Error analysis in temperature sensing with NTC and silicon-based PTC thermistors: Comparing the Ratiometric and Absolute methods

October 16, 2019 By Aimee Kalnoskas

thermistors

by Hadi Ebrahimi-Darkhaneh, Texas Instruments A thermistor is a resistive device specifically designed to vary resistance with thermal change, and therefore follows Ohm’s law. According to Ohm’s law, a current passing through a resistive component will produce a voltage drop across that component. This voltage is proportional to the magnitude of the component resistance and […]
