                                                                                                  103JG1K is a DO-35 standard series leaded, glass encapsulated thermistor. It is using super stable NTC chips which are hermetically sealed in a glass (DO-35 diode style) package. The result is a device which exhibits excellent long term reliability and stability even when subjected to severe environmental or thermal conditions. This uniform dimensions and axial lead configuration make them especially suitable for use with automatic insertion equipment.
