Passive Components > Quality Thermistor
Manufactures through hole and SMD NTC and PTC thermistors, thermistor beads and probes, temperature probes and thermistor probes. Quality Thermistor, Inc. (QTI) was founded in 1977 to meet the increasing demand for high quality electronic components for the aerospace industry. Since then, QTI has exceeded the requirements of some of the most stringent high cost of failure applications, changing the landscape of the supply chain for the entire industry.Today, QTI continues to maintain its leadership position for mission-critical applications as well as for medical and industrial applications by supplying the world’s top companies with innovative products and services. In fact, QTI developed the highest standard for surface mount thermistors with the introduction of qualified surface mount parts to MIL-PRF-32192; supplying design engineers with fully qualified DSCC options for two PTC and three NTC surface mount package styles. Additionally, QTI has partnered with the NASA Goddard Space Flight Center for surface mount thermistors qualified to S311-P827, an industry first!
6001 Series
The 6001 Boilers and Water Heating Series is QTI’s industrial sensor line designed for a wide range of liquid immersion applications. These robust temperature sensors are engineered for demanding environments and are ideal for threading into industrial boilers to monitor or control water temperature. They can also serve as a safety device to shut down the heater in critical situations. The series is fully customizable to meet OEM specifications, including probe length, housing material, sensor type, and connector type.
