Quality Reliability Efficiency
The high precision NTC thermistor MF51E is for extremely accurate temperature measurement. It is specially designed for use in electronic thermometers which require better than average accuracy. The extremely small size allows the thermistor to respond very quickly to tiny changes in temperature. The MF51E can be supplied un-calibrated with standard tolerances or calibrated and grouped according to R at 37°C±0.01% for extreme interchangeability so as to eliminate the need for other calibrations.
• Small size, fast response and light weight
• Available tolerances: ±0.5%, ±1%, ±2%, ±3% and ±5%
• B Value tolerances: ±0.5%, ±1.0%
• Resistance calibration available at 37°C ±0.01% (see table for details of grouping)
• Long-term stability and reliability
• Excellent tolerance and interchangeability
• Available in all popular resistance values
• Dissipation constant ≥0.7mW/°C
• Time constant of ≤2.8 seconds
• Rated Power: 3.5mW
• Operating Temperature Range -40°C to 100°C
