DO-35
Glass Encapsulated Thermistors
U.S. Sensor’s low cost glass encapsulated thermistors are manufactured
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. 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)
