• High Sensitivity: in the
  2.0K to 40K range.
• Interchangeability: Conforms to standard curve.
• Magnetic Field dependence: Extremely low.
• Low susceptibility to ionizing radiation.
• Compact 0.2" x 0.095" canister package.
• High resistance at
  4.2K allows use with simple DC current excitation.
