2. Other Characteristics
2-1. Temperature Characteristics of Detection Voltage
2-2. Temperature Characteristics of Release Voltage
The shaded area in Figure 19 shows the temperature characteristics of the detection voltage.
The temperature coefficient
The temperature coefficients for the release voltage and the detection voltage have the same sign
consequently.
