Littelfuse's 102PS1J glass encapsulated thermistors are manufactured using super stable NTC chips hermetically sealed in a glass (DO-35 diode style) package. This construction results in a device exhibiting excellent long-term reliability and stability, even when subjected to severe environmental or thermal conditions. The uniform dimensions and axial lead configuration make them especially suitable for use with automatic insertion equipment. These thermistors are ideal for applications requiring precise temperature sensing and control across a wide range of environments.
