Littelfuse UL Recognized 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:

  • Temperature rating = -40 to +150°C
  • Hermetically sealed glass package
  • Excellent long-term stability
  • Tinned CCS lead wires are solderable or weldable

Specifications:

  • Resistance temperature curve = "J"
  • Dissipation constant = 2mW/°C nominal (still air)
  • Maximum power rating = 20 mW
  • UL File Number E232830 (UL Category XGPU2)
