Thermistor SPECTRUM Sensors Controls

Our Advanced Thermal Products Operation provides a broad range of both NTC and PTC components. NTC thermistors are metal oxide semiconductors that decrease in resistance at temperature increases and are normally used as temperature sensing elements in a wide range of applications. NTC thermistors have a well defined resistance versus temperature characteristic and are very sensitive to even the smallest temperature change.

NTC Ceramic Component Features

• Trimable to very close tolerances; better than ±0.1°C over a 70°C temperature span
• Configurations include discs, epoxy coated chips, radial and axial glass encapsulated and others
• Low cost
• Ideal for high volume OEM applications

PTC thermistors are ceramic semiconductors with a switching characteristic; a very steep resistance versus temperature characteristic near their switch temperature. Spectrum Sensors can provide a custom solution to a range of applications at a low cost with an extremely reliable product by adjusting a range of the electrical and mechanical parameters of the ceramic element.

PTC Ceramic Component Features

• Applications include: heating elements to overcurrent protection, liquid level/air flow and many more
• Adjustable characteristics include switch temperature from approximately 50°C to approximately 170°C, R25 and tolerance, voltage rating, mechanical configuration and many more.
