Specifications

General

Recommended excitation1: 20 µV (0.05 K to 0.1 K); 63 µV (0.1 K to 1.2 K); 10 mV or less for T > 1 K

Dissipation at recommended excitation: 7.5 × 10–8 W at 4.2 K

Thermal response time: 0.5 s at 4.2 K, 2.5 s at 77 K

Radiation effects: Recommended—Click here for more information

Magnetic field: Not recommended

Reproducibility2: ±15 mK

Soldering standard: J-STD-001 Class 2

1Recommended excitation for T < 1 K based on Lake Shore calibration procedures using an AC resistance bridge—for more information refer to Appendix D and Appendix E
2Short-term reproducibility data is obtained by subjecting sensor to repeated thermal shocks from 305 K to 4.2 K
