Aerospace & Defense

Sometimes there’s no room for error… like when you’re on Mars. QTI thermistors helped NASA’s Mars Rover accomplish its mission.

Quality is essential to QTI’s process. When manufacturing high-cost-of-failure NTC and PTC thermistors to NASA GSFC spec, we take it to the extreme. For our latest Aerospace/Defense catalog, click here.

In addition to our aerospace and spaceflight clients, defense subcontractors have long relied on QTI thermistor components. We maintain one of the largest Qualified Product Listing (QPL) offerings of any supplier.

Testing Capabilities

QTI was the first thermistor manufacturer to work with the Defense Supply Center Columbus to develop a new military specification: M32192. Now, in conjunction with the NASA Goddard Space Flight Center, we have developed a new specification for high-cost-of-failure NTC and PTC thermistor temperature sensors.

QTI’s in-house testing laboratory was designed with aerospace customers in mind. We’re fully qualified to perform all tests specified in MIL-PRF-23648 and MIL-PRF-32192. We can also perform many of the tests specified in:

  • MIL-STD-202
  • MIL-STD-810
  • MIL-STD-883
  • NASA GSFC S-311-P-18
  • NASA GSFC S-311-P-827
  • EEE-INST-002
  • TOR-2006
  • ESA 4006
  • MIL-PRF-38534 Class K and H Element Evaluation
