Cryogenic Thermistor The DC95/EC95 NTC thermistors are manufactured using proven materials and techniques, making it possible to obtain close tolerances and resistance-temperature curve tracking at a low cost. The result is a rugged, stable, easy to handle device. All DC95/EC95 thermistors are epoxy coated for stability and have a maximum diameter of 0.095". Each unit tracks a specified curve to within 0.1C or 0.2C over the temperature range of 0C to 70C. The DC95/EC95 thermistors have higher dissipation constants than glass-coated beads or probe-style thermistors and therefore can be used in circuits of moderate power levels. The thermal time constant of chip-style thermistors is comparable to that of large glass probes. This series chip thermistor is especially suitable for disposable and permanent medical product usage, as well as energy management systems, appliances, industrial equipment and automotive applications. Maximum Power Level: 0.075 watt at 25C (derating to zero watt at 100C). Dissipation Constant In Still Air: 1 mW/C. Thermal Time Constant In Still Air: 10 sec. Although suitable for applications in the temperature range of 80C to +150C, best stability is achieved at temperatures not exceeding 105C. Additional temperature ranges are available as special order items. Narrower temperature ranges may be specified for effective cost savings or to accomplish even tighter curve tracking tolerances as special order items. They are available in a large variety of sensor configurations, housings, enclosures and mountings as special order items. Quantity price breaks are available.

In this application, the thermistor is slightly self-heated by passing a small current through the unit. The heat generated in the unit is more easily dissipated when the thermistor is immersed in cryogenic fluid than when the fluid level falls below the thermistor. The resulting change in thermistor temperature is easily detected by the change in resistance. Miniature Sensors 1C Accuracy EACH 1-99 100 30.43 27.05 PTC Resettable Fuses Minimum Limit Current: The minimum amount of current required by the PTC to guarantee switching at the minimum ambient temperature. Maximum Limit Current: The maximum amount of current the PTC must be able to pass without switching at the maximum ambient temperature. In addition to the PTF resettable fuse products, a series of UL recognized PTC resettable fuses are also available as special order items. They are recognized under UL file E82830, category XGPU2 (thermistor type devices), the PTU series resettable fuse allows the design engineer to start product design with a UL recognized component.
