NTC Type TH dimensions
• The tolerance of resistance is ±5% for standard device.
• The tolerance of B constant is ±2% for standard device.
The constant is determined by the equation:
B = 3853.9 In (R25/R50)
R25 and R50 represent the thermistor resistance
at 77°F and 122°F (25°C and 50°C) respectively.
• Others: For non-standard devices, consult GE.
