The main functions of smart wearable devices include heart‑rate monitoring, step counting, body‑temperature measurement, and more. Today, we’ll focus on the body‑temperature‑measurement feature. Body temperature is a critical indicator; changes in it can reveal early signs of many conditions. The temperature‑sensing component is an NTC thermistor. Our company offers an NTC thermistor with exceptionally stable resistance values and minimal temperature‑characteristic drift, delivering high accuracy and rapid response—making it a high‑performance, highly reliable solution for highly sensitive, precision‑grade measurements.
What makes this thermistor special lies in two key aspects:
This product achieves an ultra-high accuracy of 0.05 because its resistance range is only 20 Ω.
The head diameter is 0.8 mm, enabling optimal rapid response to external temperature changes.
Product Specifications:
Dissipation coefficient: Ta = 25 ± 0.5 °C, maximum 1.8 mW/°C, in still air.
Rated power consumption: Ta = 25 ± 0.5°C, maximum 2 mW. 7. Operating temperature: -20°C to 50°C.
Thermal response time: T1 = 25 + (85 − 25) × 63.2% = 62.9°C, with a maximum of 6 seconds in a water bath.
Product appearance: The wire shows no obvious damage, and there is no resin on the surface; the resin exhibits no visible pinholes or bubbles.
Impedance and B‑value: Resistance, R37 = 30.15 kΩ ± 0.15%; B‑value, B25/50 = 3950 K ± 0.5%
