JT Thermistor (high accuracy, film type)

The JT series thermistor features a thickness of less than 500 μm and can be installed in spaces as thin as a credit card. The JT thermistors also have excellent electrical insulation and can be safely used in environments where they might come in contact with electrodes. The JT-W series thermistor  is a very small thin-film temperature sensor  with a minimum length of 11.5 mm and a max. thickness of 600 μm. SEMITEC’S JT thermistors are fully compliant with RoHS DIRECTIVE2011/65/EU.
