NTC thermistor application example in medical devices
     NTC thermistor has been widely applied in various monitoring instruments. Monitor for the clinic environment (such as operating rooms, emergency rooms, intensive care wards, intensive care and the patient's family and increasingly common), to monitor and display a variety of major cases the patient's body, including ECG, pulse oximetry, blood pressure , respiration and temperature. Monitor can be stand-alone instrument, it may also be a multi-parameter instruments.
 
1.NTC thermistor Product performance: a) resistance Resistance value: R (25 ℃) = 10 KΩ ± 1%;
   b)NTC thermistor resistance value B: B (25 ℃ / 50 ℃) = 3950K ± 1%;
  c) NTC thermistor resistance voltage test: AC 1200 V / 3S no breakdown or flicker (cut-off current of 1mA);
d) NTC thermistor insulation resistance test: DC 500V greater than 100MΩ (between lead and protective tube);
e) NTC thermistor temperature range: -20 ℃ ~ + 120 ℃.
