Littelfuse precision interchangeable thermistors are low cost, highly accurate, stable devices designed specifically for temperature sensing and control applications. They are particularly suited for uses where their precision interchangeability eliminates the necessity for costly individual circuit calibration.

Features:

  • High accuracy
  • Fast thermal response time
  • Low cost
  • Small size
  • Epoxy encapsulated
  • Excellent long-term stability
  • R-T Curve-matched

Options:

  • Special lead materials and lengths
  • Special encapsulants or probe housings
  • Non-standard resistance values and tolerances

Specifications:

  • Interchangeability accuracy of ±1.0°C (0°C to +70°C)
  • Thermal time constant: 1 second max. in a well stirred oil bath, 10 seconds max. in still air
  • Dissipation constant: 1 mw/°C
  • Maximum power rating: 30 mw at 25°C derated to 1 mW at 125°C
  • Operating temperature range: -80°C to +150°C
  • Storage and operation temperatures for best long-term stability: -80° to +120°C
