Leaded Thermistors
Glass Encapsulated Thermistor
DO-35 Standard Series Glass Encapsulated Thermistors
Description
Littelfuse low cost glass encapsulated thermistors are
manufactured using super stable 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. Their uniform dimensions and axial lead configuration
make them especially suitable for use with automatic insertion
equipment.
