DO-35
Glass Encapsulated Thermistors
U.S. Sensor’s low cost interchangeable glass encapsulated thermistors
are manufactured using super stable, precision 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. Their
uniform dimensions and axial lead configuration make them especially
suitable for use with automatic insertion equipment.
Features
• High temperature capability to 300˚C
• Hermetically sealed glass package
• Low cost
• High stability
• High voltage insulation
• Tinned CCS lead wires are solderable or weldable
Options
• Special Lead Forms
• Non-standard resistance values and tolerances
• Point matched at specified temperatures
• Tape and reel packaging
Specifications
• Thermal time constant: 5 seconds (still air)
• Thermal time constant: 0.5 seconds (stirred liquid)
• Dissipation constant: 2 mW/˚C (still air)
