PSB-S9 Thermistor

A micro-miniature thermistor with a super-fast response

With an external size of φ0.43mm, the PSB-S9 is the most compact glass-encapsulated thermistor in the world that can be mass produced. Compared to the PSB-S7, the PSB-S9 has 50% the volume and two times faster in response. It was developed for sensors requiring a very fast response, microsize and high reliability. The PSB-S9 is used for office equipment such as printers and copying machines that require a fast response. It is also used in non-contact sensors and further, such as medical equipment, where micro-miniature sensors are required.
