Amphenol’s NTC type CR-1 chip thermistors for use in harsh environments are now available in Europe at TTI. The devices incorporate the high performance NK chip thermistors on tin-coated Alloy 52 leads with a high performance acid and moisture resistant coating. The coating offers a combination of properties that can be used in applications where moisture, high temperatures or chemicals can damage other thermistor coatings.

The Thermometrics CR1 coating is one of the most advanced high performance coatings on the market. Originally developed for the automotive industry for harsh environment applications such as exhaust gas recirculation (EGR) systems, air intake manifold (AIM) sensors and temperature and manifold absolute pressure (TMAP) sensors, the coating offers a unique combination of properties that can be used in many applications where moisture, high temperatures or chemicals can damage other thermistor coatings and can cause corrosion at the coating-wire interface.

Amphenol’s NTC type CR-1 chip thermistors operate from -40 to +190˚C with excellent stability and high thermal shock resistance. They have a small body diameter and weigh 0.18g. Insulation resistance is to 1kV DC and they are designed for accurate temperature measurement, control and compensation.

RoHS compliant and AEC Q200 Rev D qualified, the thermistors are available on bandolier to IEC 286-2. Suitable applications for Amphenol’s NTC type CR-1 chip thermistors include automotive, aerospace, marine, military, process control, industrial, white goods and healthcare.
