EPCOS AG NTC Thermistors B57421V2103J062

The Epcos NTC thermistor, part number 01AC8278, is a surface-mount device (SMD) with a zero power resistance of 10 kOc at 25¬8C. It is designed for temperature measurement and compensation applications. The thermistor features a multilayer construction with inner electrodes and nickel barrier termination, ensuring excellent long-term aging stability in high-temperature environments. This thermistor operates within a temperature range of -55¬8C to 125¬8C and has a maximum power rating of 210 mW at 25¬8C when mounted on a PCB. The resistance tolerance is specified at ¬±3% to ¬±5%, and it has a dissipation factor of approximately 3.5 mW/K. The thermal cooling time constant is around 10 seconds, and the heat capacity is approximately 35 mJ/K. The device is available in a standard case size of 0805 (2012 metric) and is RoHS compliant. It is delivered in blister tape on a 180-mm reel, with a 330-mm reel available upon request. This thermistor is suitable for applications requiring precise temperature sensing and compensation.
