p is the ?lled with lead shape (1: twist, 2: without twist).
ppp is the ?lled with Total-length codes. (25mm, 30 to 150mm interval 10mm, ex. 050=50mm)
Operating Current for Sensor rises Thermistor's temperature by 0.1°C
Rated Electric Power shows the required electric power that causes Thermistor's temperature to rise to 30°C by self heating, at ambient temperature of 25 °C.
Operating Temperature Range: -40°C to +125°C
