NTC thermistor chip optimized for direct embedding in power modules
TDK Corporation presents the new L860 NTC thermistor chip which can be directly embedded into power modules and used within sintering and AI-heavy wire bonding. Its characteristics correspond to the common MELF-R/T curve with R100 of 493 Ω. The lead-free chip with ordering code B57860L0522J500 is designed for a wide temperature range of -55 °C […]
Thermistors, thermocouples, and RTDs for thermal management
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?
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
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
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
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
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
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 […]
