Thermistors Offer Maximum Application Flexibility

A new line of interchangeable NTC thermistors combines precision and performance with application flexibility and convenience. The IN series thermistors deliver a high degree of accuracy with tolerances as tight as ±0.10°C in an operating temperature range of -50°C to +150°C. An exact adherence to resistance-temperature curves makes them interchangeable with any other thermistor of the same specifications without recalibration of instrumentation. These IN series thermistors come in five temperature ranges: -20°C to +50°C; 0°C to 50°C; 0°C to 70°C; 0°C to 100°C; and 20°C to 45°C. Dissipation constant is 2 mW/°C in still air, or 13 mW/°C in stirred oil, with a typical thermal time constant of 0.75 second in stirred oil. Lead types include tinned copper, tinned alloy, nickel, red Teflon alloy and Ag/Cu twisted Kynar with outside diameters of 0.008", 0.010", 0.126", 0.156" or 0.169" in standard 2" and 3" lengths. Other lengths can be specified. Chip coatings include phenolic, epoxy and uncoated. SELCO PRODUCTS COMPANY, Orange, CA. (800) 229-2332.
