S-1009 Series
3. Other characteristics
3. 1 Temperature characteristics of detection voltage
3. 2 Temperature characteristics of release voltage
3. 3 Temperature characteristics of hysteresis voltage
The shaded area in Figure 16 shows the temperature characteristics of the detection voltage in the operating
temperature range.
The temperature change
The temperature change of the release voltage and the detection voltage has the same sign consequently.
The temperature change of the hysteresis voltage is expressed as
