Thermistor Element

PL Series PL3

High precision in a wide temperature range

A thermistor chip with low B constant is sealed in glass while keeping the features of PSB-S thermistors. A PL thermistor can cover a wider temperature control range from -50 to +300℃ which requires switching more than one conventional thermistor.
PL thermistors are available in three different sizes, PSB-S1, -S2 and -S3.
