Selco Products has added the Surface-Mount Chip Negative Temperature Coefficient (NTC) Thermistors Series to its extensive line of thermal control products. Designed with surface-mount capability for space saving economies, these cost-effective NTC thermistors provide high-sensitivity response for a variety of temperature measurement and compensation, security and monitoring applications. They are offered in multiple curve and tolerance combinations to meet exact user specifications covering a wide range of resistance values and temperature coefficients.

Performance characteristics include resistance values of 25°C at 100,000 Ω with standard tolerances of ±1%, ±3% and ±5%. Dissipation constant is 0.9mW/°C in still air, with a maximum power rating of 4 mW to 6 mW at 25°C. Other features include an operating temperature range of -40°C to 125°C, fast response time due to PCB surface mounting and low capacitance.

The Surface Mount Chip NTC thermistors measure just 0.8 mm x 1 mm (Type 0603), allowing high-density placement on the board. Uniform shape and size enables pick and place assembly for faster installation. Excellent long-term stability characteristics make them suitable for critical applications in industries such as medical, military, aerospace, industrial telecommunications, computer peripherals and science.
